Cannatrol Cool Cure

Retain more terpenes, potency and increase yields on every harvest

When drying, curing and storing your harvest, an unstable environment and uncontrolled moisture are the enemy.

After putting so much care into the grow process – you’re only half way there. It is critical to assure flowers are dried, cured and stored in a clean, controlled environment. We take the guess work, the myths and the ‘broscience’ out of the post harvest process. The Cool Cure is designed to consistently deliver the perfect drying, curing and storage conditions for your harvest. Vaportrol® Technology creates an environmental equilibrium that protects and preserves terpenes and potency. Buds will remain sticky, supple and tasty for months and months. No shake, no overdrying – and no burping jars.

Our patented Vaportrol® Technology controls the process with gentle water removal using the power of vapor pressure. Program the conditions you prefer and the length of time. Extend the cure to your liking!

No burping, no maintenance. Just a really cool cure.

The Proof is in the Lab


Terpene Retention: Vaportrol Technology retained 16% more total terpenes than the traditional drying method. Specific terpenes such as Alpha-Pinene, Beta-Pinene, Myrcene, cis-ocimene, and B-Caryophyllene showed significantly higher concentrations in the Cool Cure method, with increases ranging from 6% to 23%.

Cannabinoid Preservation: While the total cannabinoids were not significantly different between the two methods, the Vaportrol system showed less decarboxylation of cannabinoids, indicating a better preservation of these compounds. Specifically, THCA, CBD, and CBC concentrations were significantly higher in the Cool Cure method, suggesting less degradation due to controlled temperature and humidity.

Environmental Stability: The study found that the traditional drying systems are subject to large environmental fluctuations, which can adversely affect flower quality. In contrast, the Vaportrol system was able to maintain more stable environmental conditions, minimizing spikes in temperature and humidity that can lead to decarboxylation and terpene loss.

Smooth and
precise dry cycles

Your unit will arrive preprogrammed with default settings that have been tested and proven. The process starts with gentle, controlled water removal.  The dry cycle will run for 4 days and the cure cycle for 4 days. After 8 days your flower will be shelf stable and ready to consume, however longer cure and hold times will often improve the quality of your smoke.  You have the ability to change the temperature, dew point and cycle duration based on  your own preferences!

Perfectly controlled
curing - no burping

A cure could last anywhere from 4-30 days (and beyond) depending on the cultivar and your personal preferences.  Select your temperature and dew point and the Cool Cure cures your harvest in a perfectly controlled environment for as long as you like! No burping, no maintenance.
You can customize the temperature, dew point and duration (although the factory settings are tested and proven to deliver great results).

Note that the Cool Cure will operate best at ambient room temperatures of 74 degrees and below. Wet load should not exceed 2.2 pounds.

Cannatrol Cool Cure

Store and save flower,
right in your unit

When you are satisfied with your cure, you can store your buds right in the unit (we use in an uncoated paper bag). The Cool Cure will hold about 4 pounds of dried buds in perfect condition for months to come (…just another reason to get a second unit).

Our Cool Cure units are built in Vermont by Vermonters.  We build the units by hand in our workshop and then run quality testing to assure every unit is working perfectly before shipment.  We know that your Cool Cure will change the way you think about Drying, Curing and Storage.

We offer a 1 year warranty on parts and labor and we stand behind every unit we make.

Please note that all sales are final.

8/1/2022 I recently ordered a Cool Cure for my soon-to-harvest in CA. I just completed the 4-day dry, 4-day cure session, and I have to tell you I have never seen such well cured bud. I was not surprised, because I researched the Cool Cure thoroughly. It is always nice to get what you paid for. My friends thought I was crazy to spend that kind of money, but the laugh is on them. Thank you for contributing to the growing world. Growing is a passion of mine and you made the hardest part of growing SUPER easy!! Thank you so much!

Gain control with our patented Vaportrol® tech

Patented Vaportrol® Technology levels out the curing, drying and aging/storage environment in every season, climate and geography. It takes the guess work and the risk out of seasonal humidity, and temperature swings. With this unique technology, you have complete control of the drying and curing process.

Why Relative Humidity (RH%) is NOT a Good Measure
Let’s nerd out for a minute here…

Relative Humidity (RH%) is probably one of the most misunderstood terms we use when referring to drying and curing. RH% is made up of 2 absolute numbers: Dry Bulb and Dew Point Temperatures. This means that you can have the same RH% at 50° degrees and 80° degrees.

Think about that for a minute… by using temperature and dew point we control the Vapor Pressure… and have 100% control of the process.

Vaportrol Technology stabilizes conditions. There is never ‘excess’ free water so you can hold your flower in the perfect environment.
No Burping – No Kidding

Frequently Asked Questions

Some of the most common questions we get about the Cannatrol Cool Cure.

Is there a warranty?


The unit is warrantied for parts and labor for one year.  After one year, we are happy to service the unit for the cost of parts and shipping.

How do I clean my Cool Cure?

Do not clean with bleach or harsh chemicals!!  If needed, wipe down the inside with warm water and use the can of compressed air that came in the stash box to clean out the drain hole.

Do I need to hang my plants before loading them into the box?

While you do not have to, the drying process will be faster if you do in addition to trimming the buds off the branches.  If the branches are left on, the drip pan will need to be emptied more as there will be more free and available moisture for the unit to remove.

Can my harvest be stored in the Cool Cure and should I set it to standby or cure mode?

Yes!  You can store your harvest in jars or any vessel that is open to the environment inside the Cool Cure.  The unit can be left in standby mode for storage use. We set it to 68/54 and store in vapor permeable paper bags or open containers- make sure to keep the sponge damp and you’ll have fantastic flower for months to come!
