Can marijuana seeds expire?

Yes, cannabis seeds spoil, just like any other seed. Or any other organic matter, period. However, weed seeds can last for a long time. In fact, they can be viable for more than 5 years, if properly stored.

Even if you store them in a drawer or something, they can last a year or two. As a general rule, try to use your cannabis seeds within the first three years of obtaining them. Five years is considered too old for seeds. The faster you can germinate and use your seeds, the better.

In fact, the longer you wait, the less likely it is that the seeds will germinate. If you have marijuana seeds that have already spoiled, no amount of darkness, low humidity, or low temperature conditions will reverse it. I placed some seeds that I had collected over the past year in what I call floating bed trays (homemade) on March 26, now here is April 2 and I haven't had any outbreaks, I expected a cold night or two still ahead, so I placed them maybe a little more than half an inch if I was still expecting some to come out or what did drop unexpectedly to 23 degrees a couple of those nights, but everything was covered and the seeds were still underground. Once the outer layer of the seed has cracked or broken, genetic information or material inside the seed is compromised.

This can cause the seed to consume its nutrient stores in the oil sac, which means that they are no longer available in the future, when actually trying to germinate the seed. If you open a package of seeds and have leftovers left over, transfer the extra seeds directly to a sealed, airtight container. A lot of times you end up not using all the seeds you bought, or you decided to keep some of the seeds that your own cannabis plants have produced because you want to keep genetics going, so you want to store them safely. But 85% of these seeds germinated and now 5 weeks after being vegetables and they grow more vigorously than some seeds I bought a few years ago.

Sticky Seeds has enjoyed great success within its niche and is known as one of the most trusted cannabis seed stores in England. If you purchased the seeds from an online seed bank, it's likely that they were mailed to you in a vacuum-sealed container. We'll answer “how long do cannabis seeds last” and give you some tips to get the most out of your seeds. Cannabis seeds need a certain degree of oxygen in their environment, but too much of it can cause bacteria and parasites, not to mention that it could dry out the seeds.

Even though seed banks recommend planting weed seeds within a year of purchasing them, they can have a shelf life of up to five years if stored properly. If you store your seeds properly, they could last a good five years, some have claimed that germinated seeds have been stored for more than 10 years, so it's always worth taking a look at them before discarding them. It's also important to start with quality seeds, so make sure you buy seeds from a reputable seed bank. The seeds should be stored in the dark, so cover the glass jar so that no light enters, cover the seeds inside the mason jar, or make sure the storage location is in complete darkness.

Cannabis seeds have a half-life of one to two years, but shelf life can be significantly increased if cannabis seeds are properly stored.
