This is why every germination method out there involves exposing your cannabis seeds to a certain degree of moisture. So, if you don’t want your cannabis seeds to germinate too soon, you need to keep them as dry as possible.
A humidity level of no more than 5% at most is recommended for both short term and long term marijuana seed storage. Yes, this can be hard to accomplish depending on where you live, but we will provide some tips for this later on today.
Yes, cannabis seeds need oxygen in order to germinate, so, without oxygen present, they won’t germinate. Moreover, bacteria and all sorts of parasites all need oxygen too, so if you don’t want your seeds being infested by pests, keeping oxygen to a minimal level will be beneficial too.
Well, the easiest way to tell if your cannabis seeds are still viable or not, is by simply trying to germinate them. Now, healthy weed seeds are usually pretty dark, a nice dark shade of green, and they should be fairly round and smooth.
Well, it all does depend on how you store them, as well as the quality of the cannabis seeds and the strain, but generally speaking, 5 years is the maximum amount of time cannabis seeds can be kept without them going bad.
If your weed seeds are really pale in color, even white, or they look all shrivelled, chances are that they will not longer germinate.
Once you have vacuum sealed the seeds, you can then wrap the plastic in something dark, or even wrap it with some duct tape, to keep light out, but you will still need to store it in a cool place. Generally for this, you can put them in the freezer or fridge.
However, seeds stored in the fridge will normally last about a decade, while seeds stored at room temperature will have a shorter lifespan.
Germination rates will naturally decline the longer seeds are kept.
