Freeze drying cannabis (live cure) is an alternative to traditional drying and curing. In this thread I’ll show real results, pros and cons, and whether freeze dried cannabis actually works.
It’s often marketed as a way to preserve terpenes and speed up drying—but what does that actually mean for growers?
We’ve tested it ourselves using a Harvest Right freeze dryer.
Here’s what it is, how it compares to traditional curing, and what kind of results you can actually expect.
Real Results (Same Crop Comparison)
Here’s where things get interesting.Same plant. Same harvest. Different drying methods.
Left: Freeze dried
Right: Traditionally dried
You can immediately see:
- structure differences
- color retention
- overall appearance
What Is Freeze Dried Cannabis?
Freeze drying removes moisture from cannabis using very low temperatures and a vacuum, instead of slowly drying it over several days.Instead of:
- hanging plants
- controlling humidity
- slowly curing over weeks
freezing the material, then pulling the moisture outIt’s fast, controlled, and produces a very different end result.
Freeze Dried vs Traditional Cure
Freeze Dried
- Very fast (hours instead of days/weeks)
- Preserves volatile compounds well
- Unique texture and appearance
- More “raw” profile
Traditional Cure
- Slower process
- Flavor develops over time
- More forgiving for beginners
- Industry standard for a reason
What Is “Live Cure”?
“Live cure” is often used to describe cannabis that’s processed immediately after harvest using freeze drying, instead of being traditionally dried and cured.There’s a lot of marketing fluff around this term, but at its core:
It just means freeze dried fresh cannabis
How Much Water Is Actually Removed?
This surprised us.This is the moisture pulled out during the process.
It’s a good reminder just how much water is in fresh cannabis.Before vs After (Same Batch)
Before going into the freeze dryer:
After freeze drying:
Same material—completely different end state.
Close-Up: Freeze Dried Bud
You’ll notice:
- very pronounced structure
- trichomes still intact
- a different “feel” compared to cured flower
Harvesting for Freeze Drying (What to Expect)
One thing that doesn’t get talked about much is how freeze drying changes the way you harvest.
If you’re used to growing big, showpiece colas—you’ll need to adjust expectations a bit.
Most home freeze dryers (like Harvest Right units) have limited tray space, so:
- Large colas won’t fit as-is
- Buds need to be broken down into smaller pieces
- You’ll be loading trays, not hanging branches
It’s a different workflow:
harvest → break down → load trays → freeze dryNot necessarily a bad thing—but definitely something to be aware of before you try it.
Using a Freeze Dryer (Settings That Worked for Us)
Freeze drying isn’t something most home growers will do—it requires specialized equipment like a Harvest Right freeze dryer.But if you already have one, here’s what worked for us consistently:
Settings used:
- Initial Freeze: -20°F
- Extra Freeze Time: 12 hours
- Drying Temperature: 45°F
- consistent structure
- good aroma retention
- repeatable results
You may need to adjust depending on:- bud size
- moisture content
- strain characteristics
Pros & Cons
Pros
- Extremely fast drying
- Good terpene preservation
- Consistent results when dialed in
- Interesting alternative to traditional cure
Cons
- Expensive equipment
- Not accessible for most growers
- Different texture (not everyone prefers it)
- Doesn’t replace a proper cure for many users
Is Freeze Drying Worth It for Home Growers?
For most growers: No—you don’t need this.You can grow excellent cannabis with:
- proper drying
- proper curing
- patience
- interesting
- effective
- but not essential
Final Thoughts
Freeze drying works—and it produces a unique product.But it’s not a replacement for good growing fundamentals.
If you’re curious and already have the equipment, it’s worth experimenting with.
If you’ve tried freeze drying yourself, I’d be curious to hear your results—especially what settings worked for you.
If you’re just starting out:

I gotta admit living out here in the Mojave the best upgrade to my grow was my Freeze Dryer, even better then my minisplits. It finally fixed the last part of my grow that was suffering. It wasn't cheap but worth it, lol.
although I highly recommend smoking it but I'm game
