Yes. We believe making the highest quality rosin has more to do with finesse than brute forceEach of our rosin presses, whether it be manual or automatic, provides anywhere from 3 tons (6,000 lbf) to 8 tons (16,000 lbf) of pressure. Our Helix manual series, which includes the Helix 3-ton and the Helix Pro 5-ton rosin presses, are perfect for artisanal, small batch rosin production. Our manual presses are built with a custom-engineered, easy to twist lead screw that provides unparalleled control during your press. The Helix offers up to 3 tons of force (6,000 lbf) and the Helix Pro offers up to 5 tons of force (10,000 lbf).Our Longs Peak and Pikes Peak V2 automated presses are designed with custom US fabricated oil-less, maintenance-free pneumatic cylinders that offer the perfect amount of force for pressing rosin. Not only that but when used with clean, dry compressed air their lifespans are measured in the millions of presses. The Pikes Peak V2 offers 5 tons of pressure, or approx. 10,000 lbf @ 120 PSI. The Longs Peak offers 8 tons of pressure, or 15,300 lbf @ 140 PSI.All of our rosin presses offer incredible reliability AND even pressure distribution. Even better, with our integrated LCD Pressware technology, the pressure at the bag is calculated for you! Through extensive testing we have discovered that extremely high pressure does not equate to significantly higher yields, and furthermore, excess pressure only serves to push undesirable material (such as lipids and inert organic particles) into your rosin, thus reducing its quality.

All PurePressure rosin presses were engineered with safety as a key priority and offer industry-leading safety features not found with other rosin machines. The primary safety feature is that our rosin presses require two-handed operation to engage rosin pressing, ensuring that nothing is accidentally caught between the plates, ever. In order to begin squishing, a user must depress two buttons on opposite sides of the front of the machine for 5 seconds, by which time both heat plates have come into contact.There is also a prominent emergency stop button located on the left face of each Pikes Peak V2 and Longs Peak rosin press, which immediately retracts the heat plates and restarts the software on the press, turning off the plate heaters in the process.Finally, you can retract the heat plates at any time during a press by pushing "A"on the command panel.
Yes. PurePressure's custom designed, 100% aluminum heat plates qualify for food-grade manufacturing and processing when used with adequate parchment paper, such as our 35lb premium vegetable parchment.
We machine our plates out of aluminum in-house, as opposed to stainless steel, for better heat distribution. Stainless steel distributes heat unevenly, which can use discrepancies in your rosin when pressing. We do offer stainless steel plates if requested at a small additional fee.
The Longs Peak rosin press offers 60% more force than the Pikes Peak rosin press and is capable of processing twice as much material per day, approximately. It features all of the same incredible technology, including our Pressware touchscreen interface, with an 8 ton pneumatic cylinder. For ROI and processing information, click here.
All four of our rosin presses proudly feature our Pressware LCD touchscreen technology, which offers a level of control that no other rosin press on the market even comes close to. PurePressure's Pressware is delivered from our completely custom hardware (no Arduino or Raspberry PI here!) and our fully proprietary software. Here are just some of the things you can do!
Crystal Clear Full Color Touchscreen
PurePressure's LCD touch screens are in a class of their own when it comes to rosin presses. With a beautiful full color display you have more insight than ever before, including at-the-bag pressure readings with pre-set bag sizes.
Control Every Variable
From temperature and time to multiple pressure stages and more, controlling every aspect of your rosin press is better than ever. You can even change your settings from Imperial to Metric. Tap, save, press.
Save Up To 30 Recipes
Once you dial in how you want to press your flower, kief, or hash, repeat those results 100% consistently every time. Name, store, and save up to 30 per-determined instructions which can be as simple or as granular with your settings as you can dream of.
Navigating and using the Pressware system is extremely simple. Everything is right in front of you, so no digging around to find your last run data, quick press, or to load your favorite recipes. Perfecting your pressing process has never been easier.
The automated pressure control kit allows processors to replace their Dual Pressure regulator system with a fully digital pressure control unit, thereby dramatically increasing material throughput and ease of use, even with the most difficult to press materials. This upgrade kit is available for all PurePressure rosin presses as a one time, plug-and-play upgrade, which runs on our Pressware™ system.
The Dual Pressure Upgrade Kit is extremely helpful for pressing kief, dry sift, hash, and bubble hash to avoid bag blowouts completely. Our upgrade kit enables you to ramp up from a lower set pressure to a higher pressure, at your command.
This upgrade kit is highly recommended for anyone who intends to press kief or bubble hash.
When you're squishing hard to press material, such as greasy bubble hash or kief, the amount of rosin oil trying to escape the bag is much higher than when you are pressing flower, trim, or shake. If you apply too much force too quickly, it can rip your bag open and you have to start over. With the Dual Pressure Upgrade Kit, you never have to worry about that again. By starting your press at a very low pressure, you can let the heat liquefy the oil properly and start escaping, and then increase the pressure slowly to ensure you get the maximum yield.
The Dual Pressure upgrade works by allowing you to start at one set pressure, and then ramp up to a second set pressure with the toggle switch. This is especially helpful when making rosin with hard to press material, such as kief, dry sift, hash, and bubble hash.
There are three positions the toggle switch operates in: left, middle, and right. The left orientation always will use the left regulator's pressure, the middle orientation is neutral and will hold whatever pressure you have set, and the right orientation will increase pressure with the right regulator up to the maximum it is set at.
Start by setting your desired pressures on both regulators, with your starting (lower) pressure on the left regulator, and your maximum (higher) pressure on the right regulator.
Before pressing, ensure that the toggle switch is set to the left so that it starts at your initial pressure.
Once you've engaged your rosin press, the LCD will readout your initial pressure. To increase pressure, change the toggle from the left position to the right position, which will increase your pressure to the desired amount.
This is completely up to you, the user. We frequently use the vertical orientation with the Pikes Peak V2andLongs Peak rosin presses but many of our press owners use the Pikes Peak V2 or Longs Peak horizontally to take advantage of directional flow rosin pressing and gravity-assisted dripping.It is extremely easy to switch the orientation of our rosin press, so we encourage users to try squishing both ways to see which they prefer!
The Helix and Helix Pro manual rosin presses do not require an air compressor. Our automatic presses have the following compressed air requirements: Pikes Peak V2: CFM: 1.7 or greater Tank size: 30 gallons or more recommended, 10 gallons minimum PSI: 130 or greater Longs Peak: CFM: 2.2 or greater Tank size: 30 gallons or more recommended, 10 gallons minimum PSI: 150 or greater Visit here to see our full air compressor document.
You can either buy a top notch air compressor from usdirectly, or you can go to your local hardware store to pick one up, such as Home Depot or Lowe's. Recommended Requirements Your Air Compressor Should Meet: Pikes Peak V2
CFM: 1.7 or greater
Tank size: 30 gallons or more recommended, 10 gallons minimum
Tank size: 30 gallons or more recommended, 10 gallons minimum
PSI: 150 or greater
When we're advising customers on which air compressor to purchase, we usually ask them the following questions:1) Are you just planning to use it for your Pikes Peak V2 or Longs Peak rosin press, or do you have other equipment to use, too?2) What is your tolerance for noise?3) What is your budget?Consider your own answers to those questions, which should help make the decision much easier. Unless you're on a tight budget, we always recommend making the investment in a high quality compressor, such as the USA manufactured ones that we sell from Quincy and Chicago Pneumatics. They will last much longer and consistently provide clean, dry air which is critical to the operation of your press. If the higher tier air compressors are out of your price range, don't fret - the Pikes Peak V2 rosin press works perfectly fine with smaller compressors, and to mitigate noise, you can always route the hosing through a wall or put the compressor in a closed-in area.
Ideal actuating speed on the Pikes Peak V2 or Longs Peak rosin press depends on if you are pressing kief or ice water hash versus flower. For kief, dry sift, and ice water hash, you will want to slow down your actuating speed as much as possible, which means 1-3 full rotations out. For flower, trim, or shake, you will want to increase your actuating speed so that your plates make contact quickly, which means between 4-6 full rotations out. Your Helix or Helix Pro rosin press is capable of unparalleled precision with the twist handle. See section 5.2 in the user manual for tips on effectively avoiding bag blowouts and getting the maximum yield, every time.
Virtually none!All PurePressure rosin presses were engineered specifically to not require regular servicing, although there are some things to keep in mind to ensure that your press always is running smoothly. Helix and Helix Pro (Manual):★Do not lubricate the left or right Internal Guide Rods. ★Do lubricate the screw threads using food-safe grease by PurePressure. ★Use an adequately grounded power outlet or a surge protector.★Do not exceed your press’s force limit by more than 1,000 lbf.★Use your press indoors in a clean, low-dust room. ★Remove power, then use denatured alcohol or rubbing alcohol to quickly clean your heat plates when they are at room temperature.★Every 2,000 presses or so, fully retract your plates and put a light coating of the included Screw Juice (food grade screw grease lubricant) on your lead screw. Pikes Peak V2 and Longs Peak (Automated):★ Ensure that you are only using clean, dry compressed air when operating the press. This will increase the life of the air regulator and the internal air transfer components. The pneumatic cylinder is oil-less and maintenance-free.★Use your press indoors in a clean, low-dust room.★ Use parchment paper every time you press to keep your heat plates free of oils and debris. If you do get oil on your heat plates, they can easily be cleaned with denatured alcohol. We recommend that you clean your heat plates when they are not hot to avoid any burns.★ Do not operate the Pikes Peak V2 press at over 120 psi, or the Longs Peak press at over 140 psi. The internal components are rated up to 150 psi, however using air pressure over the maximum rating with any frequency taxes the components above and beyond what they are rated for.
Our four presses all offer a narrow premium 6061 aluminum heat plate assembly design and are designed to allow the rosin to escape the heat quickly, thus preserving the maximum amount of terpenes. The heat plate sizes for each of our rosin presses are listed below: Helix:2.5" x 4.5" Helix Pro: 2.5" x 7" Pikes Peak:2.5" x 10"Longs Peak: 3" x 10"Each heat plate kit on our presses feature 4 total premium quality
heating rods, with both top and bottom plates utilizing their own
thermocouple for perfectly accurate temperature readings.
Yields range significantly and depends largely on the quality of the materials used. Great material in = terrific rosin.
Trim: 3% - 8%
Shake: 8% - 15%
Flower: 15% - 30%
Kief / Dry Sift: 30% - 60%+
Bubble Hash / Hash: 30% - 70%+
Note: Adequate application of pressure is important to achieve optimal yields and these figures are based on averages we have tested using properly packed rosin bags. Results may vary and depend heavily on your material as well as the skill of the rosin press operator.
Currently we are in the process of obtaining official UL certification for our rosin presses.
Every electrical component in our press is UL listed however, so rest assured that we've carefully selected every component to be as safe and functional as possible.
Fire department officials we have spoken with in a number of states have told us that UL certification is not currently a requirement for rosin press use, but we are working to get ahead of the curve on this important issue. If you think this might be a concern, we recommend checking with your local regulators to get a clear answer.
All four of the rosin presses we manufacture do not require any regular cleaning. As long as you are pressing your rosin between high quality parchment paper, such as our 35lb Ultra Bake premium parchment, your heat plates will remain clean.
If you do end up accidentally getting some rosin on the press itself or just want to remove any fingerprints, simply use some rubbing alcohol or a similar denatured alcohol product with a rag or paper towel.
Yes. Our artisanal rosin press series includes the Helix 3 ton and the Helix Pro 5 ton manual presses. Both are designed with a custom-engineered, easy to twist lead screw for pressure application. Neither of which require an air compressor and can even be used on your kitchen counter!
The Pikes Peak V2 and the Longs Peak rosin presses are available in both 120v and 240v electrical versions as (operating voltages are set at the factory, not by the user, so please contact us for more information). Both utilize a standard USA 120 or 240 volt outlet and draws approximately 8 amps while heating up for 10-12 minutes, and then passively draws 2 amps during normal operation. The Helix rosin press runs on 120/240v with 3 amps required at startup and 2 amps continuously used during operation. The Helix Pro also runs on 120/240v with 4 amps required at startup and 2 amps continuously used during operation. In any given full 8 hour day of using our presses, it will only consume around 1 kilowatt of energy total with near-constant use, thus making it extremely energy efficient.
No, an infrared heat gun will not give you an accurate temperature reading. Even extremely expensive ones do not have the ability to accurately read temperatures on reflective surfaces.
PurePressure's Pikes Peak rosin press utilizes two separate heat plate assemblies, each with two heating rods and a thermocouple. For this reason, we're extremely confident in the accuracy of the temperature readings as well as the heat output. The thermocouples require no calibration and we verify that they are within spec long before we they are installed in our presses. The discrepancy in temperature when using a heat or temperature reading gun actually comes from how the infrared thermometers operate. The reflectivity of a surface has a dramatic effect on the temperature reading when using infrared and a shiny surface (like our heat plates) is the worst case scenario. Ideally you need to have a matte black surface for an accurate reading. The only way to accurately spot check the temperature would be with another thermocouple, thermal paste (to ensure good thermal transfer), and a controller to amplify and filter the thermocouple signal.
Simply put, the cost of our rosin press is directly a reflection of the craftsmanship and quality of its components. With us, you're making an investment for the future - not just a purchase that won't go the distance. You truly get what you pay for with us at PurePressure, and that means a professionally-engineered piece of cannabis extraction equipment with an incredible team to support you. Check out our Why Our Press page to learn more about the incredible technology we've put in our equipment.
Many of our competitor's presses are made in China with low quality components and weren't even manufactured specifically for rosin in the first place. If you're curious, take a peek on Alibaba.com to see how few of the rosin presses you may have seen are actually assembled in the USA!
Finally, the original prototype pre-production Pikes Peak rosin press is still the one we use today for demos and at our shop, which is a testament to its durability. Come see it for yourself and contact us today to set up a live demo at our warehouse in Denver, Colorado!

Yes, unlike Brute trash cans or other non-food grade plastic vessels, the Bruteless series is made from 100% durable, sanitary stainless steel. This ensures that no micro-plastics are left behind in the wash process, due to the vessel you are using.
We strongly recommend deep cleaning your Bruteless stainless steel vessel, fittings, and paddle at the end of each day’s washing. This will help ensure that your system stays contaminant free, which is crucial. RO water can be extremely corrosive; surface rust can appear even on stainless steel because of rogue particulate in standing water on the metal. We have two different cleaning recommendations depending on if you are cleaning your lines or the stainless steel surfaces of your system.
The Bruteless insulation jacket is composed of a shell and a core. The shell is neoprene and can be wiped clean with isopropyl alcohol if needed. The core is a moisture resistant closed cell foam and should not absorb liquid.
The goal when using a hand paddle is to create turbulence in the wash, which is what separates the trichome head from the stalk and plant material. When the paddle moves through the water, it creates vortices on the edges of the paddle. The solid paddle will create a vortex that curves and follows the paddles edge. The solid one may be a little more gentle on your material turbulence wise but it is a little harder to move through the wash. The paddle with holes will have a vortex on the edges of paddle as well as the edges of each hole, creating a bit more turbulence. The paddle with holes offers quite a bit less resistance than the solid one. That means less fatigue on a person hand washing, which can definitely create more consistent results.
PurePressure's Axis trichome separator is our take on an automated hash washing machine. It offers unparalleled control,
machine utilization, and scalability for solventless processors. The unique design separates the washing vessels from the source of agitation,
which enables extractors to wash in one vessel while the next one is
being filled, pre-soaked, or filtered. This creates massive efficiencies
both in terms of batch processing throughput and labor cost savings.
Built in the USA, the Axis' wash down rated stainless steel housing
allows for easy cleaning and sanitation. It also features a joystick
that's coupled with a touch screen control panel to mimic hand-paddle
agitation. Begin washing like a pro from the start with preset and
custom recipes, further increasing your ability to produce challenging
SKUs like full melt or six star hash with ease and consistency.
The Axis trichome separator works with the 30, 44, and 65 gallon Bruteless vessels. Depending on the size of your vessel you can wash, filter, and collect up to 132 lb (60,000 grams) or more of fresh frozen material per 9 hour shift.
Listed below are the capacities of fresh frozen flower (grams) that the Axis can wash with each size of Bruteless vessel at one time:
Our 220μm open wash liners were designed to help increase efficiency of your ice water hash washing process. They are the perfect solution to maximize
your Bruteless washing system’s volume while making it much easier to remove your waste flower once you have completed the wash. Plus, the 44
gallon version also fits any modified 32 gallon Brute® trash can or similar vessel. Sewn in Colorado, they're made with premium FDA compliant materials intended for food contact to ensure your bubble hash retains quality.They are not required for washing but highly recommended.
Typically, full melt hash contains trichomes that fall in the range of 90µm-120µm, but each strain and even each plant is different. The full micron spectrum range for most hash washing filter bag sets ranges from 25µm-220µm. Full melt is also achievable in some instances with very high quality dry sift, but is less common than with ice water hash.
PurePressure's Pneumatic Hash Pump is a stainless steel fluid management system that eliminates gravity draining and feeding during hash washing. It is perfect for connecting multiple/separate wash systems together in your lab.
This hash-safe pump has a gentle, low shear flow that protects delicate trichomes from being damaged. It includes an integrated control stand that allows the operator to adjust pressure and speed of the pump on the fly.
Selecting which rosin bag you will use is heavily dependent on the type and quantity of your starting material as well as the size of the heat plates on your rosin press. For ice water hash, dry sift, and kief we recommend keeping your filtration size at or under 72µm. When pressing flower, filtration between 90µm and 160µm is typically best (if using filter bags).Check out the guide below to see how much starting material you can use with each size of rosin bag. Scroll further to see more details about the uses of each micron (µm) size.
Typically you will always want to press using a rosin bag for a couple reasons, namely that they provide crucial filtration in order to achieve the highest quality rosin possible. With kief and hash rosin specifically, there is virtually no other way to do it since due to the granularity of those starting materials, simply pressing them without a bag will result in a mess of liquefied trichome heads and organic detritus.
When you use a rosin bag, it helps filter out the organic material that does not contain any cannabinoids, thus purifying your rosin and making it higher quality. You can however press flowers as-is in small quantities without a bag to get an unfiltered product, which often has small bits of plant matter in it.
Yes, absolutely. We sell rosin bags in multiple sizes and micron mesh variants to ensure that our bags are usable in all set ups. All bags we sell are sewn in Denver, Colorado with premium grade 100% polyester monofilament and are color coded for ease of micron recognition.
For example, if you're using a hair straightener, we recommend purchasing the 2" x 3" bags for ease of use. For any other heated rosin press, select the bag that closest resembles your heat plate size. We sell the following sizes:
Our rosin bags are manufactured of 100% from ultra-durable nylon monofilament mesh and hand stitched with premium polyester thread. All raw materials are FDA approved for food contact and have undergone thorough testing; see our declaration of compliance for more information.
PurePressure's premium rosin bags are made with 100% nylon monofilament mesh and are intended to be single use only. The reason for this is that after a rosin bag is placed under heat and pressure, removing the spent material and re-filling them almost always results in degradation to the stitching and integrity of the mesh itself, thus weakening it. For optimal results, use your rosin bags once, then you can take the intact bags and do a second press at a higher temperature to get the rest of the oil out. When you are done pressing, you can repurpose your spent rosin bags to make edibles if you'd like!
Yes. Along with our 25µm stainless steel mesh we also sell 5µm nylon mesh sheets that are perfect for mechanical fractioning.These sheets are designed to be used inside of our 25 Micron Stainless Steel mesh to further clean up high quality bubble hash and dry sift when doing mechanical separations. The nylon does all of the filtering while the stainless steel provides the structural reinforcement to help prevent a blowout. This combination is perfect for producing rare solventless hash products by filtering out many more fats, lipids, and very fine organic debris than is possible with a single filter.
Utilizing one of our pre-press molds will help increase your rosin yields with any material and helps to prevent bag blowouts, especially with kief, dry sift, hash, and bubble hash. This is achieved by applying pressure to your material inside the bag so that it's more evenly packed and distributed to the seams for easier oil extraction. Our molds can also be used to pre-press material outside of a rosin bag
as well. Each mold is magnetized and machined in-house out of 100%
aluminum for maximum durability!
See the video below to watch Eric Simpson use the PurePressure pre-press mold to form an even hash patty.
Our food grade 35lb parchment paper is ultra durable, non-stick, and perfect for pressing rosin or working with concentrates. Manufactured with minimal permeability, these bleached sheets significantly reduce essential oils bleeding through your parchment and onto the heat plates. Step up from cheaper grocery store parchment to the best. To top it off, it's 100% USA made! We also sell premium freeze dryer tray parchment paper to protect your hash during freeze drying.
The food grade 35lb parchment paper sheets are ultra durable, non-stick, and perfect for pressing rosin or working with concentrates.The multi-use PTFE sheets are food grade and can be especially useful for terpene separations. Collecting your rosin is typically easier with PTFE than it is with parchment paper as the surface is non-porous and non-stick.
The main differences between the two are the capacities (each Harvest Right Pharmaceutical model is about double in capacity compared to their Home models) and that the Home model is designed for food purposes. Because foods tend to contain more moisture, the Home model dries at a higher temperature which can be harmful to your ice water hash. Ice water hash is generally processed in Harvest Right's Pharmaceutical line of freeze dryers.If you plan to freeze dry your ice water hash, go with a Harvest Right Pharmaceutical model from us at PurePressure - you will receive free professionally tested freeze dryer usage instructions, and we'll beat anyone's price!
Key Differences:- The Pharmaceutical model comes with a standard vacuum pump while the Scientific model includes a 7CFM Harvest Right Oil Free Scroll Freeze Dryer Vacuum Pump. You can always purchase the oil free pump and use it with the Pharmaceutical models however, which we strongly suggest if your budget allows for it.- The Pharmaceutical models have more trays and thus a higher capacity (Small Pharmaceutical - 5 trays, Medium Pharmaceutical - 7 trays, Large Pharmaceutical - 8 trays) compared to the Scientific models (Scientific - 4 trays, Large Scientific - 5 trays)- The Pharmaceutical model is the ideal plug and play freeze dryer. The Scientific model gives users more customizations allowing multiple thermal and drying steps. It also allows the user to set their vacuum pressure making it a great option if you're looking to experiment and perfect your cycles.- The Scientific model has shelf heaters that are completely adjustable and an internal sensor that tells you when your material is dry.Ready to buy your freeze dryer? Click here to see all the options.
Aside from price point, the differences between Labconco and Harvest Right freeze dryers come down to a few things. If you'd like to learn more about what freeze dryer option might be best for your operation, contact us today.- The Labconco FDry-8L is a pharmaceutical grade freeze dryer that is geared towards professional labs and large scale labs looking to increase efficiency. While the Harvest Right models take anywhere from 18-24 hours to complete the freeze drying cycle, a Labconco can complete the cycle in around 6-8 hours. - The Labconco FDry-8L freeze dryers come with a Leybold SOGEVAC NEO D 16 Vacuum Pump that only requires an oil change every 3 years. For Harvest Right freeze dryers, unless you are using a Harvest Right Oil Free Scroll Freeze Dryer Vacuum Pump, you will be changing the oil every other use (with the standard pump) or every 20 uses (with the Harvest Right Premier Freeze Dryer Vacuum Pump).- Lastly, the Labconco FDry-8L freeze dryer offers significantly more options for professionals looking to make the very best ice water hash possible, but do require more tinkering to get the recipes perfect. We sell an SOP for them as well as each Harvest Right freeze dryer model, so no matter what you pick, we can help you run it perfectly.
Key Differences:- The Labconco FDry-8L freeze drying cycles are about 6-8 hours compared to the 18-24 hour cycles of a Harvest Right. - The Labconco also has multiple independent sensors that constantly monitor shelf temperature, product temperature, collector temperature, and vacuum level of your material to ensure consistent results every single cycle. - Labconco's built in vacuum pump protection ensures your hash is never compromised in the event of a power failure or vacuum pump error, meaning you can rest easy with every run. It also features active variable monitoring throughout the entire freeze drying process, with remote notification of alerts or run parameters so that you can be notified if there is a power outage, abnormal variables, or to simply check your run conditions from home.We offer SOPs both Harvest Right and Labconco freeze dryers, so if you aren't sure which is best for your lab, talk to us today.
The Pharmaceutical Harvest Right models can be used for food purposes. However, we recommend purchasing the Home freeze dryer shelving insert if you are using your Pharmaceutical model to freeze dry food. If you would like to purchase this, contact us. Making some freeze dried bananas or other goodies between hash batches is always fun!
Since we do not manufacture Harvest Right freeze dryers, we suggest that you contact Harvest Right directly to be best assisted with your support needs. If you purchased your Harvest Right freeze dryer from us, we'd be happy to go to bat for you with Harvest Right since they sometimes are not the fastest to respond. If you didn't purchase your freeze dryer from us, unfortunately we do not offer direct end user support.
We typically see freeze dryers run between 45°F and 55°F to best preserve the terpenes, but shelf temperatures will affect your drying times considerably. For more freeze drying tips and tricks, read this article. We also sell SOPs for Harvest Right and Labconco freeze dryers if you really want to perfect your drying cycles.
Frequently Asked Questions About Rosin and Extraction
The shelf life of rosin is similar to BHO or other concentrates in that it will last a very long time on the shelf if kept in properly sealed containers.
Your rosin's consistency depends entirely on how it's produced and stored, however rosin generally tends to automatically develop a budder-like texture if left out at room temperature. You can refrigerate your rosin like any other extract product to prolong its shelf life and preserve its original consistency for longer periods of time.
The following 3 factors heavily influence the color or clarity of your rosin:
Quality of your material
Age of your material
Temperature at which your material is pressed at
To get the best, brightest rosin, we recommend pressing your flower, kief, or bubble hash as soon as possible after it has been dried, cured, and processed from the original harvest. Quality in = quality out, and pressing too hot (typically above 250 degrees Fahrenheit) may darken your rosin as well as potentially harm the terpene profile, especially with flower rosin. Bubble hash and kief seem to be somewhat more heat resistant when pressing rosin in our experience, however.
Generally, the higher the quality of your input pressing material, the better the clarity will be, and vice versa. Same goes for age, which is another critical factor - old material tends to come out darker, although that doesn't necessarily equate to a poorer quality product.
Rosin and BHO (butane hash oil) are both cannabis concentrates, but are extracted differently. Both rosin and BHO offer comparable potencies that can range from 60-80%+ in active cannabinoids. Rosin can be manipulated into popular consistencies, such as shatter, budder, wax, sugar, and so on, contrary to popular belief that shatter is only BHO.
Rosin is the result of an extraction method that squeezes cannabinoids (THC, CBD, and their sub variants) out of cannabis material using only heat and pressure, making it solventless.
BHO on the other hand is extracted by using butane, a harsh solvent, which strips cannabinoids from the cannabis material. The resulting oil requires extensive purging in vacuum oven chambers to remove the butane so that it is consumable
Rosin and BHO both have equally comparable THC percentages and potency.
The amount of active cannabinoids in rosin or BHO mainly depends on how high quality the starting material was. Typically, this percentage range for concentrates is 60% - 90%, whereas cannabis flower by itself tests anywhere from 10% to 30% or slightly over at the most.
In the world of cannabis concentrates, a term you may hear often is "full melt" or "six-star" hash. When talking about ice water hash or "bubble hash" specifically, this is a reference to the quality of the product. Full melt means that the products entirely melts on your banger with little to no residue or debris left after.
For a thorough explanation of full melt and six star bubble hash, check out this blog article!
No. If you are pressing flower, it must be freshly dried and cured. If you attempt to press fresh frozen cannabis it will sizzle and ruin the fresh frozen material. There is far too much water in fresh frozen cannabis to apply direct heat and pressure.
Washing fresh frozen cannabis with ice water, shears off the trichomes via turbulence and agitation. When the plant material is frozen, it creates a more brittle surface that can snap off much easier than if it was not frozen.
Test washing is sometimes done in a sealable glass jar with about 12-24 grams of fresh frozen flower, ice, and water. These jar sized batches are typically not dried and processed, therefore you won't get a weight or any numbers from this. However, this works great as a visual testing method for comparing strains side by side. More experienced processors will use this method because they know what to look for.
For beginners looking to see how their starting flower will yield, your best bet is to wash at least a few hundred grams in a bigger vessel. Eric Simpson (Instagram: @simpsonsolventless) recommends washing 1,000 grams (fresh frozen weight) in a 20 or 32 gallon vessel. This way you will be able to collect the hash, weigh it, and gather proper data from your test wash to further calculate yields on your starting material.
The lower the temperature in your wash room, the better. An ideal wash/ extraction room will be around 60°F or lower. Hash is much easier to work with when it is kept cold, when it is heated it becomes tacky and starts to stick to everything it touches.
Yes. Reverse osmosis water is necessary in the hash washing process. RO water is filtered and stripped of all minerals, microbes, and potential contaminants. This is extremely important as non-RO water such as tap water will leave minerals (or other microscopic elements) behind in your hash after the freeze drying process.
Ice water hash can be stored in an air tight container or glass jar in the freezer for months. It is important to keep the ice water hash cold and preserved so it doesn't begin to lose terpenes and "grease up" before it is time to consume it or press it into rosin.
