Storing Cannabis Seeds – Some Handy Dos and Don’ts

Storage Keeping your cannabis seeds safe and viable is essential. To help you get the most out of your “magic beans”, here are some handy dos and don’ts for correctly storing cannabis seeds.

10-handy-dos-and-donts-for-storing-cannabis-seeds-4kCannabis seeds are a valuable investment. You may fortunate enough to live in a place where growing them is legal (in which case, lucky you; we hope you are taking advantage of this to grow as much cannabis as possible!). You may be stockpiling seeds to preserve your favourite genetics for the day when your local legislation changes in favour of cannabis growing. You may even be one of those rare people who really is buying cannabis seeds as collector’s items. No matter which of these groups you belong to, keeping your cannabis seeds safe and viable is essential. To help you get the most out of your “magic beans”, here are some handy dos and don’ts for correctly storing cannabis seeds.

1. DO – keep your cannabis seeds dry.

Damp or wet seeds will begin to germinate, and even small amounts of moisture or humidity inside packaging can cause rot and mould.


2. DON’T – let them get too warm.

Warmth will also encourage germination, and high temperatures can damage cannabis seeds, effectively ‘cooking’ the insides.


3. DO – keep them in the dark.

Darkness encourages seeds to remain dormant; long exposure to light may damage and degrade the health of the seeds.


4. DON’T – squash them!

Pretty obvious really, but make sure the shells remain intact. The shell is the seed’s natural defence against outside elements.


5. DO – keep them labelled.

Cannabis seeds do tend to all look very similar; make sure your strains don’t get mixed up!


6. DON’T – let them get too cold.

Freezing cannabis seeds will damage at least some of them. The door of a fridge is the ideal temperature (5 – 6 degrees centigrade).


7. DO – keep your hands, working area and any equipment clean and dry.

Mould and fungus can grow on seeds even when they are refrigerated.


8. DON’T – let pests or rodents get to your cannabis seeds.

Keeping them in the fridge is a good way of ensuring this also.


9. DO – make sure you buy cannabis seeds from a reputable seed bank, such as Sensi Seeds or White Label Seed Company.

Seeds should arrive in the original packaging and be clean and solid.


10. DON’T – pack your cannabis seeds with NON-FOOD GRADE silica gel.

Or anything else that could be toxic!



Following these handy tips for storing cannabis seeds should keep the original germination rate (which, if you bought seeds from a reliable seed company, should be around 95%) unchanged for at least two years, and potentially as many as five! After some years, the germination rate will gradually decline. However, thanks to the naturally stubborn survival traits of cannabis, there is no deadline at which all the cannabis seeds in a batch will suddenly lose the ability to germinate. Anecdotal reports of cannabis seeds that were over 20 years old when they were germinated and still produced a 60% germination rate can be found on various cannabis forums, so with correct storage, your precious seeds will remain an investment for years to come!

Can food grade silica gel cause the seeds to dry out too much if in an enclosed container? After all, they'll just keep sucking up moisture if they don't fill up.

is it ok to store cannabis seeds in room temperatur for a couple of months?

Hi there,

Thanks for your question. Of course it is impossible for me to say with any guarentee, but if your room is around 20 degrees C or lower, and it's only for two months, this should not affect your germination rate. Do make sure you keep them dark and dry though, and try to refrigerate them as soon as possible.

With best wishes

Can cannabis seeds be damaged,by the warmer weather in the post?

Thanks

Hi Karen,

If the seeds were in a very hot place for several days, it is possible that the germination rate might be affected, but in the normal course of deliveries, this is not something that would cause problems.

With best wishes,

Thanks for the information. If I had read this article I may have saved many seeds that I have been saving that refused to germinate this past season. I just would say to all the readers to AVOID any seeds from Humbolt Seedbank. They are a rip-off from the word go.!!!!!
