Male cannabis plants typically release pollen four to five weeks after flowering. To ensure maximum viability, it's important to collect the pollen just as the sacs begin to open. Once the pollen has been released, the plant will start to age and eventually die. To collect the pollen, you can use a garbage bag or other storage container.
In the 1990s, Henk van Dalen of Dutch Passion created female cannabis pollen that would produce only female plants. This revolutionized the production of cannabis seeds and put Dutch Passion on the map. Today, breeders and suppliers of cannabis seeds can create extensive pollen files from the best individual specimens of the best varieties. For them, storing cannabis pollen in the freezer may be a more convenient option than trying to keep a room full of cuttings. A recent study funded by the Canadian government discovered a new way to store cannabis pollen indefinitely by drying and combining it with wholemeal baked flour, preservatives, and then freezing it in liquid nitrogen.
This method is especially useful for those who want to grow their own strain or produce their own cannabis seeds. When collecting cannabis pollen, it's important to wear a mask or respirator to prevent inhalation. Once collected, you can dilute one part of cannabis pollen with four parts of finely ground dry powder for added protection. Cannabis pollen is usually viable for two to three days under natural conditions. To ensure maximum viability, it's important to collect and store it properly.
With the right techniques and materials, you can store cannabis pollen for an indefinite period of time.
