As I've said before, I lost my 2+ zips of my 1st grow from 3 yrs ago to bad storage practices that I do not want to repeat so I have been doing some research and planning this method to preserve the form as well as actives.
Oven drying - I don't have a dehydrator but I do have an elec oven that I can dial down to 140 (checked w/ turkey probe) for initial dry in 3-4 hrs. Caps are cracker but stems still pliable.
MGSO4 desiccant - I've seen Damprid and Dryrite, but I'll trust MGSO4 over either of those as on the off chance some does infest the product, laxatives may be inconvenient but are never toxic
dry ice - While I haven't researched this in depth for interaction, i do know of the non-reactive nature of CO2 and it's natural way to purge oxygen by being heavier and forcing all other gas out of a vertical container with the lid off.
vacuum sealer - the salvation army had a foodsaver w/ lid attachment and 2 boxes of bags for $15 so it will be my huckleberry
The plan is oven dry, desiccant finish, dry ice in a jar/bag (I still need to research how much solid CO2 phases into how much gas), add boomers, wait for DI to "melt", vac seal w/ food saver (no oxy absorber), and stick in the freezer.
Any tweaks/caveats that members would like to alert me to about this "deep storage" tek idea?
I'm at the desiccant step ATM.
