It's not hard to actually find accurate info regarding this
I wouldnt advocate vac sealing a volatile substance...think about the vapor pressure of terpenes present and what that vacuum is doing
Light is all you really need to worry about with bud.
Try reading studies, papers that start with abstract
The long term stabilityof cannabis resin and extracts
A
ustralian Journal of Forensic Sciences (Impact Factor: 0.7).09/2010; 42:181-190. DOI:10.1080/00450610903258144
No degredation of neutral thc (not thca) over the 4 year study period with a 35 day half life of thca in dark at room temp
Light is the enemy here. Even at 170° theres only a 5% loss converting the more sensitive thca into thc.
Thc beimg significantly more unstable than cbd or cbn
Cbn will still slowly form in the reezer due to enzymatic processes, unrelated to thc degradation
Though limiting o2 will also help.
In other words, mold of any type typically cant thrive under 60% rh. Keep that under control, in a sealed container. The vp will equalize and wont loose more terps. Temp should be ~40-50
For very long storage... as in your grand kids could smoke it... the bud itself wilp break down some during this time. The cannabinoids induce cellular apoptosis in cannabis tissue....
As far as seed storage...again a little research can go along way, or just general education
i have seeds +20 years old.
have had some loose in trucks tool box through seasonal changes. some in the freezer, some just sitting in a dresser.
the viability of all is the same. same germ rates, which are quite good. even crushed seeds have given me 50%
if your storing for a long period as in measured in decades.. go for your freezer. otherwise it really doesnt matter.
i like 60% and 60°. for normal storage
I wouldnt go below 20% humidity..
like with decreasing humidity till you hit the lower critical moisture content. longevity is also improved once you reach the UPPER critical moisture content. at this level respiration is allowed to occur and the seed actually repairs damage it would receive or say to dna over time.. in extremely dry conditions the seed could also die from the rapid water absorption. they first should beexposed to humid air...
