Airtight Storage Jars
There have been a number of scientific experiments in recent years which point decisively to the best ways of storing marijuana for long periods of time. While the studies themselves are technical and are oriented toward laboratory procedures, cultivators can benefit from discoveries.
The first principal developped by researchers is that the handling of the marijuana is very important. The glands which contain the resin are very effective containers and protect the components from oxidation, moisture and light. But these glands will burst under only slight pressure and it is inevitable that many of them will be broken open during harvesting and drying. But if you want your marijuana to last, take care to treat it gently as possible in all stages of handling.
Of course, many methods of preparation, paricularily traditional Eastern styles, involve trampling and compressing the fresh marijuana to release the resin. This is done because of the commercial value of aroma and texture and not because long-term storage is desired. In fact, most commercial ganja will deteriorate within a year to the point where it is not smokable.
The most important negative factor in the storage environment of marijuana is light. This is true whether the cannabis is stored in herbal form, extract or solution. In the case where cannabis is stored as extract and solutiuon form, the effect of exposure to ordinary indirect sunlight is dramatic. In a number of experiments, the THC content of resin solutions went from a healthy 5-10% to practically zero in as little as a week of exposure to the level of light found in an ordinary northern exposure room. Experiments with cannabis in herbal form showed far less dramatic drops in THC but did demonstrate that over a period of, 6-12 months, light is the most significant factor in degeneration of THC content.
Cultivators will do well to store their marijuana in a dark place or in a container reasonably impervious to light.

Another important environmental factor in the storage of cannabis is the temperature in the storage area. There is no particular advantage to keeping your stash in the fridge. In fact, the best storage conditions seem to be right at ordinary room temperature, about 65 F. It is important to avoid high temperatures for even short-term storage. Temperatures of over 100 F will cause significant degeneration of the psychoactive principals if they persist for more than a few weeks. The exception to this rule is the high temperatures found in the curing process. Under the special enclosed conditions desirable for curing, high temperatures have a most useful effect in converting cannabinols to THC. But for long-term storage of marijuana high temperatures are out.
While we're talking about storage temperature, let me mention a problem more or less widespread. A few years ago a popular book on marijuana recommended that people who wanted to make superdope should put their dope in a closed container with some dry ice for a while. This was supposed to vastly increase the potency of the stuff. What really happens when you do this is that alot of carbon dioxide crystals form in the cells of the plant material. When the dope is smoked the carbon dioxide is released as carbon monoxide, a toxic and deadly gas, present in the combustion of all organic materials but present in huge amounts of grass which has recieved the dry ice treatment. Also, there is no increase in potency. Clearly, this is not a good idea.

The last important factor in the storage of marijuana is oxidation by air. Many experiments show this a primary cause of degeneration of the active compounds in marijuana. To counteract this problem requires that the cultivator be sure that the container he uses for storage is as airtight as possible. Even ordinary containers can be made reasonably airtight by using a piece of wax paper under the lid as a gasket. Also it is easy and cheap enough to buy almost perfectly airtight containers from canning supply sources.
To summarize : airtight storage of gently handled marijuana in a dark place at room temperature is ideal for keeping THC content of your marijuana at a peak for the longest possible time.
