Male cannabis plants will produce pollen several weeks into their flowering cycle. Once their pollen sacs have opened up and released, the plant will begin to senesce and eventually die. It is important to collect pollen right as the sacs are beginning to open up, as this is the time pollen is most viable.
For both seeds and pollen that have been frozen long-term, it’s important to avoid defrosting until they are ready to be used. Fluctuations in temperature and moisture content will quickly destroy their viability, so maintain a steady temperature for as long as possible. Warming and freezing multiple times isn’t good.
Cannabis is for the most part dioecious, meaning that the male and female reproductive organs exist on two separate plants (although hermaphroditic plants do occur). It is also a wind-pollinated plant, so pollen must be transferred from a male stamen to a female pistil via the air in order for pollination to occur and seeds to form.
When storing seeds, place them in an air-sealed container that doesn’t have any light leaks. Film canisters, medicine bottles (non-translucent), and any sealable storage jar will work fine. The idea is to reduce the amount of oxygen present in the storage space as much as possible. You can also add uncooked rice to the storage container, which acts as an absorbent, to reduce moisture content.
A grower or breeder can also freeze the progress of a breeding project for months or years without losing any of the long, hard work. Endeavors such as phenotype hunting and maintaining desired mothers for breeding and cloning can all be saved for later through genetic preservation. This process is like backing up work on a hard drive.
Fresh seeds should have a germination rate close to a 100%, whereas older seeds will see a significant drop off over time in their ability to germinate.
Fortunately, preserving genetics for long-term storage is easy and will save time, money, and space in the long run. Through seed and pollen collection, you can hang onto those genetics that you can’t fully get rid of and safely store them for future use.
MSNL Seedbank also offers tons of freebies allowing you to save money in the long run and make it a good choice to bulk. Just like with other seed banks on this list, they have a wide range of strains available, sadly the lack of a germination guarantee is disheartening.

3. Crop King Seeds – Best Global Shipping
Weed Seeds Express is a newcomer to the cannabis seeds industry but it has the potential to be the number 1 product on this list. The only reason why it’s not our featured product is that it hasn’t built up a reputation for itself and we’re still waiting for possible negative reviews about the product.
All of the seed banks on this list offer high-quality marijuana strains and reliable shipping. However, we’d wish that they can work on their website more to make things more convenient for their customers. For example, make things easier for their customers to find out important details about their product such as which ones are on discount and which ones are the top products.
If reliability is the most important trait you want in any vendor, then you’re going to love Gorilla Seed Bank. It’s one of the best seed banks on this list when it comes to the reliability of its stocks. The reason for this is that Gorilla Seed Bank tries to keep their stock fresh and new, preventing you from buying old and worn-out seeds that may have dipped in quality.
