Can you freeze dry marijuana? What about hemp?

Freeze drying isn’t just for removing water from fruits and vegetables! Freeze-drying is an excellent way to preserve cannabis and hemp at the peak of freshness.

However, not every cannabis freeze drying method does the job right. Other freeze dryers and techniques render the flower dry, with a loss of valuable terpenes. Cryo Cure is the best freeze drying method on the market for producing a flavorful and potent flower with cannabinoids preserved, terpenes enhanced, and trichomes intact.

Should you freeze dry cannabis or hemp? Why?

Yes! Freeze drying cannabis is a sought-after cannabis drying and curing method. Promoted by master breeder Ed Rosenthal, hobbyists and commercial producers alike have long explored how freeze drying can improve shelf life and reduce damage-causing moisture. Additionally, it’s a preferred process tool for extraction artists preparing flower and biomass for all types of extraction. Higher yields and superior quality, stabilized.

Can you use a regular freeze-drying machine for cannabis?

While it is not uncommon for cannabis consumers to use a freeze-drying machine at home, these devices are not designed or programmed to preserve cannabis or hemp. (However, Cryo Cure machines can also be used to freeze-dry flowers and food.)

Do you have to rehydrate the cannabis after freeze drying it for smokable flower?

NO. It’s never a good practice to rehydrate your flower after any drying and curing method. It defeats the purpose of Cryo Curing.

What is the main difference between Cryo Cure machines and a regular freeze-drying machine?

Cryo Cure machines utilize a patented process fine-tuned specifically for cannabis and hemp, resulting in a final product that we call “Cryo Cured” cannabis. The machine dials in the right combination of time and temperature to preserve the delicate trichomes that contain phytocannabinoids and terpenes. Regular freeze-dring machines have no such settings.

About the Cryo Cure Process

How is the Cryo Cure process different than regular freeze drying?

Cryo Curing is a patent-pending process that applies to a specific range of time, temperatures and pressure, tested and proven to perfectly preserve cannabis and hemp in its “live resin” state. Traditional freeze-drying methods pull out valuable cannabinoids and terpenes. Cryo Cure is designed to preserve trichomes, terpenes, and cannabinoids, resulting in more potent and flavorful cannabis or smokable hemp flower.

How long is the CryoCure cannabis drying process from start to finish?

The drying process takes only 12 to 14 hours. The final curing time lasts approximately 6 hours depending on the cultivar. Then, it’s ready for packaging.

Who has endorsed Cryo Cure?

Cryo Cure is proudly endorsed by Danny Danko, Senior Cultivation Editor, High Times Magazine; “Ganja Guru” Ed Rosenthal, co-founder of High Times Magazine and a longtime cannabis author, cultivator, and activist; world-renown cannabis breeder and advocate Rick Naya; pure cannabis terpenes expert Tony Verzura of Blue River Terpenes, and more. You can watch endorsements on the Testimonials page.

How long does Cryo Cured flower last?

When stored properly in an airtight container, at stable temperatures, and away from direct sunlight, Cryo Cure can be stored for at least one year and for up to two years.


How long is the freezing process?

The freezing process is a minimum of 2 hours at -20°F.

Can you pre-freeze the flower before Cryo Curing?

Yes, you can pre-freeze your flower for at least 2 hours at -20°F before going into the Cryo Cure machine. This shortens the time flower spends Cryo Curing to 12 to 14 hours, plus one “burp,” to even out the desired moisture.

Does cannabis need to be wet trimmed before Cryo Curing?

Cryo Cure can be wet trimmed or dry trimmed before Cryo Curing. You may prefer wet trimming during large runs because sugar leaves tend to act like hook and loop closures, which can make it more difficult to separate stacked buds. If you keep the sugar leaves on, arrange the cannabis in a uniform, single layer.

What is the average moisture content of Cryo Cured flower?

Cryo Cured flower falls between 8 percent and 12 percent moisture content.

What is the final active water content of Cryo Cured flower?

Smokable flower is at .50aW and .60aW.

Are there different settings for different cultivars?

Cryo Cure machines are not preprogrammed for specific cultivars. However, you may find that certain time settings may work better for some cultivars (strains). You can save your preferred times as presets on the machine.

Can you Cryo Cure multiple cultivars (strains) at one time?

Yes! There’s no need to separate cultivars to Cryo Cure your flower. However, you may find that you prefer how some cultivars turn out when different settings are applied.

Does every Cryo Cure machine have a built-in freezer?

Freezing is required before using Cryo Cure. To that end, the CC240 and CC350 models have built-in freezers. The CC720 has an option to add a freezer. You can also purchase a walk-in freezer from Cryo Cure; we have 10×10 and 20×20 options available. Our freezers are manufactured in the United States.

How big are Cryo Cure machines?

  • Model CC260 is 48” by 29” by 37”.
  • Model CC360, 78” length by 62” width by 96” height. Dry and cure between 66 and 132 pounds of wet weigh-in cannabis or hemp per cycle.
  • Model CC720, 72″ by 96″ product chamber, 625 square feet of shelf space, 8.5′ tall by 15′ long by 6′ diameter, 600 lbs. to 1200 lbs. wet weigh-in, depending on whether the material has been pre-frozen.

What if I have more product than the machine holds?

No problem! Your flower can be frozen independently from our machines in a separate deep freezer or a walk-in freezer that reaches -20°F to -30°F. In this case, the drying cycle time is approximately 12-14 hours, which can double the amount of product Cryo Cured in a 24-hour period.

Do you lose total crop weight when using a Cryo Cure cannabis freeze dry machine versus traditional cure?

No. Our patent-pending process leaves your flower with a perfect moisture content of 8 to 12%. Though the cannabis looks larger than the stated scale amount, remember that there is no shrinkage to the flower. This means 1 gram in weight is double the size it would be if traditionally cured.

How are Cryo Cure machines serviced?

Cryo Cure machines are serviced on site by your local HVAC service provider or electrician. These professionals can replace parts or perform service on Cryo Cure machines. That’s what makes Cryo Cure great – there’s no specialty, pricey maintenance involved.

Can you make cannabis or hemp CBD products out of Cryo Cured flower?

Where can I get Cryo Cure?

The number of dispensaries carrying Cryo Cure is growing each day. Currently, Cryo Cure cannabis can be found through official dispensary partners in Colorado, California, and Michigan.

Describe the Cryo Cure consumption experience. What’s it like?

The Cryo Cure process preserves THC-A and results in little to no Delta-9 THC and CBN. These cannabinoids can cause a heavy-feeling high. Without their presence in a Cryo Cure product, consumers can expect a more energetic and uplifting experience.

Does Cryo Curing cannabis preserve terpenes and trichomes?

Yes! In fact, Cryo Curing cannabis preserves the “live resin” flower in its natural state, with little to no Delta 9 THC or CBN.

What does the traditional freeze drying process do to cannabis and hemp trichomes? How is Cryo Cure different?

Traditional freeze drying can make tiny trichomes too brittle to stay on the flower. As these trichomes fall off, flower loses its potency, both for cannabinoids and terpenes. Cryo Cure’s process does not damage the terpenes, so they are as vibrant and fresh as they were the day the flower was picked from the plant.

Can a consumer tell the difference when they try Cryo Cured cannabis?

The difference is immediate! First and foremost, there’s no shrinkage, so buds look bigger and more beautiful. Cryo Cured cannabis also boasts a longer shelf life if properly stored in light-blocking, air-tight containers. Best of all, the smoking experience is unparalleled: inhalation is smooth, the experience is uplifting, and the product tastes and smells exceptional, thanks to Cryo Cure’s terpene preservation.

Does Cryo Cured flower have a chlorophyll taste?

No! Our global patent-pending process removes the chemical called cic-3-hexanol (C6H120) that is responsible for the “green smell and taste” otherwise known as “leaf alcohol.”

How will I know that I’m purchasing a Certified Cryo Cure product?

All Cryo Cure products have the certified “Cryo Cured” branded seal. The Cryo Cure name is globally trademarked, and our logo is only authorized for use on officially licensed products in the states in which we sell Cryo Cure.
