Currently using deep freezers to get longest life out of flower both fresh or cured. Cured I double freezer bag and let acclimate several hours before open bag when taking out. Happy with results.
Been keeping them at -20 but thinking it’s a waste of energy, does anyone have experience doing this at 42 (refrigeration temp) vs freezing, does it degrade noticeably faster?
Freezing cured flower ? That’s a new one
Personally it s never on the shelf so long
As for freezing your flowers wonder if the water content 8-12% is not rupturing your cell walls (lyse) with negative effects
Cool dark ando airtight maybe a slight vacuum is all I do
I’ve had headstash stored for a few years come out like the day I put it in. If there is rupturing it doesn’t seem to have much effect on quality.
I had the most longevity with cured flower right around 50F - so just above normal refrigerated temperatures, but often possible using existing refrigeration with temperature control devices in place.
I didn’t have to double bag.
I did this study for terpenes, THCa, and coloration study. I did it over an 18 month period with 16 different strains. I didn’t see a noticable change in color. I did see a substantial drop after about 9 months in terpenes - and then moved to a better sealed container, which really helped. I did see some decarboxylation into D9-THC, but I did not see any degradation into CBN, even after 18 months.
This was chilled, long curing, material. We still monitored the material (indicators in each unit). And that monitoring included what might be considered standard burping until the moisture content leveled out to right around 45% RH ~9% moisture content.
That’s a little drier than most people seem to want - but it also stayed good for a very long time.
This was when I was running Copperstate Farms. So 500,000 plants - harvesting thousands of plants a day - drying, curing, and trimming hundreds of pounds a week. I had extra during some parts of the year - and it was an appropriate business decision to STORE SOME so that in winter, even though we were still harvesting, we would still have enough to meet demand.
I had a pretty robust quality program there.
So yeah - can you do it, sure. I never even considered freezing anything that wasn’t going to go for extraction. Breaking those cell walls like @Roguelab says isn’t good for color, bud structure, and maintaining trichome integrity, in my experience.
For sure the level of drying contributes to this - as does how much curing you have done to let those sugars and chlorophyll degrade before freezing.
Let us know if my method of partial refrigeration works for you - or if you have better success at refrigerated temperatures.
The luxury of a safe stash 
Darn politcs
This is perfect, just what I was looking for thanks man
