freezing weed seeds

When they are exposed to temperature changes or light, cannabis seeds begin using their store of nutrients.

For short-term storage, place the seeds in a container with desiccant. Seal it, and place it in a cool, dark place.

What’s the Right Storage Temperature?

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.

Another option is to freeze the cannabis seeds. If you go down this route, please ensure that you vacuum pack them first. Then put them in a dark container. Also, it would help if you germinated these seeds immediately once they come out of the freezer. Don’t allow them to thaw first.

If you only require short-term storage, a dark drawer or cupboard is sufficient. The most important thing, regardless of the duration of storage, is to avoid temperature and humidity fluctuations. Rapid variations in temperature, in particular, can destroy your seeds. If you live in a location with warm daytime temperatures and cold nights, avoid outside storage.

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.

A few basic things to remember are, always store seeds in a cool, dark, dry location, and never let them see direct sunlight.

When cannabis seeds are properly stored, most growers find the majority are still full of life after five years. Many growers have even grown high-grade cannabis with seeds up to 10 years old.

THE ATMOSPHERE IS KEY – COLD, DRY & DARK

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.

Furthermore, seeds should never be exposed to direct sunlight and should be kept in a dark, dry place. Excess light and humidity can lead to premature germination. Ideally, 9% or less humidity is preferred.

Some people who live in regions where there is a lot of cannabis activism and reform are currently stockpiling seeds of their favourite strains to grow when it’s legal in the future. Whatever your reason may be for having seeds, remember that taking care of them is one of the most important things you can do for your harvest.

It’s also important to note that when freezing seeds, every time they are thawed and refrozen, they become less viable. Both freezing and refrigeration can also lead to excess moisture, so that’s something that needs to be monitored closely.
