best dessicant for cannabis seeds

3) Cannabis seeds kept in the same conditions will store for over 10 years and still have nearly 100% germination.

For skuff what is needed is an air tight container that has another small porous container in it containing a rechargeable desiccant. This is all that is needed for drying skuff at normal room temperature. A couple of ounces of silica gel will completely dry 6 oz of skuff.

I have had several queries about drying skuff properly before making it into hash for long term storage. Using a desiccant is a simple way to do this.

1) The best way to make sure that fresh skuff is not holding on to too much H2O, is to dry it in an air tight tin or glass container. It takes a week to 10 days for tumbled skuff and a little longer from a bubble bag. Once the skuff is dry it can be kept in a sealed air tight container for several years at freezing point with virtually no loss of potency. During that storage time a lot of the volatile terpenoids change and mature giving the final hash once it is pressed a totally different type of flavour and high.

2) Pollen kept in a very low humidity environment at near freezing or deep frozen will keep for months if not longer.

For seeds use the same thing but in addition small porous containers are needed to store the seeds. It is important not to keep the seeds in the polythene/plastic bags used by the seed companies as they are impervious to water. The airtight container should be kept between 0 and 5 Centigrade, the salad crisper tray is fine.

Desiccants are substances that have an affinity for water and will rapidly absorb any moisture from the atmosphere around it.

Since desiccation-tolerant seeds stop almost all metabolic activity as they mature and dry, they can be stored for months or even years with only minor loss of viability and vigor. Desiccation-tolerant seeds which show high germination percentages when fresh—if properly dried and stored in a freezer—can typically retain their viability for years.

Seeds with low initial germination rates will begin to lose viability fairly quickly, however, even under ideal storage conditions. Seed lots with a low initial germination rate should be regrown as soon as possible. If a batch of seeds with poor germination is grown out and a healthy batch with good germination produced from them, the healthy batch can then be dried, frozen and stored for long periods successfully.

Seeds air-dried during humid weather require additional drying with desiccants such as silica gel before final storage (but don’t use heat!). Most seeds benefit from drying with silica gel if they are to be stored for very long. The longest storage life for desiccation-tolerant seeds is achieved by drying them to between 5% and 7% moisture content (by weight) and then storing them at several degrees below freezing. As storage temperature rises above freezing or moisture content rises above 5 to 7%, longevity in storage goes down and the incidence of mutation rises. Seeds dried to a low moisture content with silica gel and then stored in a freezer can usually retain viability for many years.

Avoiding Problems With Stored Seeds

To use silica gels for drying seeds, place equal weights of dry silica gel and seeds to be dried in a well-sealed jar for 7 to 8 days. Then transfer the dried seeds quickly into airtight storage jars and place in a freezer, refrigerator or other cool, dark place.

Mold and Mildew: A common problem with stored seeds is mold or mildew resulting from incomplete drying before storage. Dry your seeds thoroughly before storing them (though drying them to 0% moisture will of course cause their death). If seeds sweat on insides of jars during storage, they are too wet and must be dried further in order to store successfully. At this point the use of a desiccant is a good idea. Don’t tarry, because damp seeds will mildew quickly.

Temperature and Moisture Fluctuations: Fluctuation in temperature or moisture levels of stored seeds lowers the seeds’ longevity significantly, causing loss of viability and vigor or even seed death. Rapid moisture fluctuations are particularly damaging to seeds. High moisture or temperatures encourage mutation of seed tissues—especially in root tips, which remain more active than other seed tissues. Cellular mutations affecting metabolism or root tissue structure are a common cause of seed failure upon germination. Dry your seeds properly before placing them in cold storage. Keep your stored seeds at a constant temperature if possible and remove them from storage as seldom and as few times as possible. When seeds are removed from cold storage in order to retrieve samples, allow the entire container to come slowly to room temperature before opening the seal. This will help prevent condensation of atmospheric moisture onto the cold seeds which might otherwise occur.
