If you don’t begin with great seeds, you can forget about producing a harvest of high-quality marijuana. A lot of growers seem to forget one simple fact: Your seeds are alive! Although cannabis seeds are fairly durable, improper storage can ruin them. If you’re paying $10-$20 a seed, losing a full batch is an expensive mistake.
In this guide, we outline how to store and preserve your cannabis seeds. We focus on the following:
Keeping Light Away from Your Marijuana Seeds
It would help if you also stored your seeds as high above the ground as possible. This reduces the possibility of a pest like a rodent coming in and feasting on the seeds.
You can ‘test’ your seeds once you have removed them from storage. Place them in water. If they sink, they should be fine. However, if they float, it is more likely that they are bad seeds. You can still try to germinate, but there is a greater risk of producing poor-quality cannabis, or else the seeds fail to sprout. You can keep floaters in water for approximately 72 hours to see if they sprout a tail.
Imagine paying $100+ for seeds, going to the trouble of storing them, only to find that insects ruin them. Unfortunately, all you need is one insect in a container to destroy all of your seeds. The first consideration is to avoid exposure to ultra-low humidity. However, for long-term storage, this is precisely what you are supposed to do!
With the correct method of storage, cannabis seeds could remain viable for 5-10 years! Read more about how to store seeds the best way!
Frequent inquiries from new growers are often related to cannabis seeds. How can they be stored safely? How long will they last in storage? Will they retain the same qualities as newer seeds? When stored appropriately, yes, you can grow prime cannabis plants with decade-old seeds, just as you could with seeds that are only a few months old.
WHY IS PROPER SEED STORAGE NECESSARY
As mentioned above, seeds require cold temperatures so they don’t lose their essence. Either freezing or refrigeration will do. However, when keeping seeds in the refrigerator, keep them as far back as possible so they won’t be exposed to any temperature changes when the door is opened.
If only being stored for a few months, cannabis seeds should do fine in a grip-seal bag, placed in a mason jar or some other type of airtight container. For more long-term storage, a vacuum-sealed package is a much more popular option. Many seasoned seed-savers like to add a food-grade desiccant to their package as well.
Cannabis seeds should be stored somewhere cold and frigid. Whether you store your seeds in a freezer, refrigerator, or even a cabinet or drawer, it’s important to leave them there until it’s time to germinate. Rapid temperature variations will destroy the genetic integrity of your seeds.
