Long Term Storage of Extracts

What would be the best type of extract to store long term , I understand the terpins(??) will degrade in less than 1 year but what about the THC,and CBD how long can they last ???


Can the terpins store longer if in tincture form ??

Cannabinoids are terpenes.. being put in solution is best because it stops oxidation, though while in solution light is even bigger of a factor. Light is the arch enemy of thc, if your hash is stored in a dark and cool place, and sealed. I would expect it to last 2 years, after 4 years you can go ahead and toss it......for better info vacpurge reworked a link for me in the iso thread. Its got graphs and multiple scenario's....in any case under best conditions thca was gone in 240 days and 2-4 years for thc depending on environment

Absolute in ethanol solution changed color from light yellow to dark amber
during storage half a year at room temperature in the dark,
but similar solutions have not changed in the freezer.
In the first place should be temperature and not light.

Instead of trolling. Read the study, its not my info, I didn't conduct it... every study I have read and my background lead me to believe thc's biggest fear is light. I also have seen this from personal experience.. you are suggesting all these studies were wrong?

I'm not trolling, take it easy. I just report you of my observation, no offense. From common sense it is not clear why the light doesn't hurt resin on live plant?

That's a strong question MiG especially since the best outdoor grow's in conditions of extreme light saturation from a plants point of view. Granted the plants goal in life wasn't to get you high but to find some pollen so it's hard to say which factor is more deleterious from the human's point of view. This is more of a preservation issue than a live plant issue so I'm going with temperature over lights not that both arn't critical. My sauerkraut for instance can go fine on the countertop for a few days but if the temp's go over 40c it will go completely poison on me in the same amount of time. Light's an enemy but it's a passive killer, temp's are an active killer.

I'm sorry but again that's wrong. This is not a matter of opinion.....this a quote from me on pg 10 iso thread." The ultra-violet rays activate such bonds to form free radicals, which then react further with oxygen in the atmosphere, producing carbonyl groups in the main chain. The exposed surfaces of products may then discolour ,although in bad cases, complete product disintegration can occur.

Polymers which possess UV-absorbing groups such as aromatic rings (thc and other cannabinoids/aromatic terpenes) may also be sensitive to UV degradation. Aramid fibres like Kevlar for example are highly UV sensitive and must be protected from the deleterious effects of sunlight......remember that thc is a phenol ... but its an aromatic mono terpene as well"

The plant produces thc all its life in the same ratio as other cannabinoids all its life. Even in veg and seedling a plant has trichs covering every inch, though they may not be visible to the naked eye (roughly 2% thc in veg). The plant continually metabolizes, recycles and produces until its life cycle is complete. At which point the heads stop producing precursory cannabinoids. Terpenes at this point cyclicize and product is now degrading. Visible by heads turning amber......and actually the sun throws an average of 7k lumens at most about 10. This is equal too 110k roughly in lux. My 600 watt cool tube out performs the sun at closer than 8 inches

Sunlight kills the green chlorophyll in alcohol, turning it into an amber for a couple of hours.


But the cannabinoids in the secretory cavity of trichome are under the bright light two months of 12/12 and did not have time to hopelessly spoiled,
so whether or not to hide from the sun during extraction?

Whammo quizo king's argument put's the daggar to the gut of the argument. I mean i don't see anyone with a shred of logic storing their product's at 50c in the dark or -50 in the light. The answer is Both are mandatory dark and cool just like everything else nature seems to want to give and take back. I was just bringing a food preservation background to the argument if were talking about why people would believe one viewpoint over another. Thc is not bacterial fermentation so the concept of temp over light doesn't rule the day but merely chimes in the opposite should not be ignored. It's like looking at shatter vs wax, wtf is going on between 110 and 140 that changes the game. We know observationaly x temp is good and we don't care about the why if it yields sucess, preventing bad temps and bad uv's is no different. All im saying is in the case of extreme's over time tempuratures are more deleterious in a shorter amount of time when it comes to sensatory quality. Tasteless burnt oil still has thc but to the human the loss of terps effects the medicinal value allot more than going from 17% to 14% thc because it's been sitting in a dispensary display case under lights. That's my point, what's mattered to humans preserving things for centuries is holding onto the full experience even at the cost of the highest effect. Fresh onion's are great, pickled onions make my mouth water in my sleep. I know your right from a lab stance, but from a human stance i would still weight in "over time" bad temps make it suck for us on the whole over less bang for buck which light will kindly to thc.

When you reply back to blow my head off with the correct fact's please take into context anything i say is in regards to which is worse on preservation over "time" temp or sunlight

which is worse on preservation over "time" temp or sunlight?

Undoutably sunlight. I encourage you to look at the graphs in the article. They are degradation over 4 years (but testing all throughout)with light and room temp. Without light and room temp. And -20c with light and without...light is thcs worst enemy not heat. This has been talked about in other articles as well....it was stable I believe they said for the duration of the study period, its the second graph their talking about thca half life ect

ok I agree with you, the term room temp is dodgy outside of the 1st world but all in all if it's 23c air conditioned america room temp then by far the light will be the destroyer. I guess it's the pirate in me that thinks long term storage means putting something underground encased in a cooling stone. Underground also means a cellar if were in the 1st world. The day I get to 20kg's of oil in storage im putting it in a time capsule and planting a tree over it and calling it my century dab retirement nest egg.

Being from a different generation that's worried about clean water and uncontaminated food supply, I don't have the youthful perspective that petrochemical products will last indefinitely. The price of tane will follow the price of gasoline. So im sorry if Im thinking about storage sans the grid, light i know how to block out but managing temperatures over time over climate is much more of an issue that simply shutting a box.

So if I were to put it in a 99.9% ethyl alchool solution , under the correct conditions it could last longer than 2-4 years ??

I am literlly looking to bury it about 5 foot deep in the earth where the temp. stays a constant 52 deg. F , in a amber, glass container , then double baged in a heavy mylar bags with O2 azorbers for some insurance

I have read in a older grow book that storing for long periods of time was posible , It reported a story about a ball of hash being found somewear that was 500-1000 years old and still active in the middle of the ball . Could this even be true or just some BS

Liberty chicken your on it, stretching it out in ethanol would keep the up's and downs of any thermal extremes of freeze and roast to a minimum when talking about air. 5 feet is about right but you just have to watch your water table extreme's. If I put it 5 feet deep where I live right now I would hit a spring of water no matter where I go. Agreed on the amber too that's why i never thought light would be an issue for anyone to argue the danger's of. I didn't consider the ethanol because I wanted to seal kilo's of pirate booty i don't currently have a gram of in the big 21 qt pressure cooker's I use at home. I would probably like to fill the pressure cooker with a high rancidity resistant oil to reduce the risk of water and air even further if not to protect against earthquake. I always had this strategy for gold but I've learned it's the tree you grow over it that makes the difference rather than sinking it into the ground and putting a door matte over it. I don't know if I can handle the amount of ethanol I would need to put away the anvil's of oil I can see without it being it's own blow up potential in the event of a ground fire.

I dunno about the alum myself I'd rather clean propane tanks out and put a bulk head gasket on it. It's more something I looked at if in my area of the world prohibition and or thieve's where to get to a maurausive level, I'd need something dog's won't dig up like they can a 6 month old bone 3 feet deep. I both live in the overdeveloped world and in the tropical "farm larceny" world of the equator. If they'll steal 33 cow's in the middle of the night, they'll put a gun to my head for the oil. I know every time I have a good year i need to plant a tree that has enough oil under it to rebuild the farm after a fire or hurricane.

Yea its possible. Without light, cbd cbg and the more stable compounds won't degrade. Delta 9 will be converted to 8 after a while which is still psychoactive.. as long as its in the dark even at room temp thc was stable cooler conditions will make it last longer. It will eventually break down...after you die if stored properly
