old marijuana seeds

If you’ve tried all our tips above and still haven’t managed to germinate your seeds, it’s likely they are beyond the point of return. To avoid having the same problem next time, here are some tips to help you store your seeds:

Did you find some old seeds in a forgotten corner of the house? Well, you’re in luck; below we’ll share some simple tips to help you germinate old cannabis seeds.

If this isn’t enough, you can try carefully (and very gently) using a sharp knife like a Stanley blade to remove the ridge running along the middle of each seed. This should expose the inside of the seed a little, helping it absorb moisture and, hopefully, giving it a better chance of germinating.

LET MOTHER NATURE DO HER THING

Old cannabis seeds can be hard to germinate. Luckily, there are a few techniques that can help them sprout, even if they’ve been forgotten for some time.

1. Place 2 pieces of paper towel inside a salad plate.
2. Dampen the paper towels and place your seeds on top of it.
3. Cover the seeds with another 2 pieces of damp paper towel, then cover the salad plate with another plate, and keep it in a warm, dark cupboard.
4. Check on your seeds every 2–3 days.

This is a very popular way to germinate seeds. And for good reason; it’s pretty successful. Here’s how to germinate your cannabis seeds using paper towel:

• Some seeds won’t germinate at all. Unfortunately, old seeds sometimes just don’t sprout. So, if you try all of the tips below and wait patiently without any luck, it’s likely your seeds are just too far gone.

The problem with these stimulators is that you never know the correct dosage. The information shared on marijuana forums is anecdotal, and legitimate studies have only been performed on other crops. So, if you decide to use any of these additives, do some research or ask other growers, and always err on the side of caution.

Instead, take a glass of water and throw your seeds into it. Twelve hours will be enough for the shell to soften a little and the water to finally get inside and wake up the embryo. Don’t forget to check the seeds regularly. As soon as they crack and the taproot appears, you should take them out. Seeds are living organisms and they need oxygen. Leave them submerged for 24 hours or more, and they may drown.

So, the question of how to germinate old cannabis seeds translates to: how do you help moisture get inside your old seeds? The obvious first choice is to pre-soak them before germination.

3. Crack Your Weed Seeds

This will be enough to make a lot of tiny scratches on the protective outer layer of the shell, allowing moisture to get inside much more easily.

Some people buy a special cracking tool for old cannabis seeds. This simple contraption applies mild pressure on a seed until an audible crack is heard. Others simply bite on the seed—ever so gently—until they hear it crack.

Use a sharp knife to cut the whole length of the ridge, on both sides. Be sure not to cut too deep and damage the embryo.

If stored properly, marijuana seeds can remain viable for many years. However, the longer you keep them, the harder it is to make them sprout. More often than not, you’ll have to use different hacks to successfully germinate old cannabis seeds. We’ll teach you how, but first, let’s see what conditions make cannabis seeds come alive in the first place.

The first method is scarification. This includes causing injury to the seeds’ outer shell to allow water and air to enter, which is essential for germination. For manual scarification, we will need a container or box lined with sandpaper or any coarse material to scar the seeds’ outer surface. Put the seeds in a container or box and shake. After a while, we will find that the roots become dull, and we can see parts of the sources inside the container. Once we scare the outer shell of the cannabis seeds, we can germinate them as usual.

Below we will go through 3 popular methods used to germinate old weeds seeds. Remember that we have to do the part by trying to keep the temperature between 26 ° C – 28 ° because that is where the clones seem to season-best. You must also ensure that the seed is kept in a dark area, as light can slow down the germination process.

Cannabis seeds are known for their aesthetic properties and shape. Round and symmetrical seeds are best. Larger seeds have a reasonable rate of germination compared to small seeds, which tend to be immature.

Method 1 – Scarification

Method 3 requires that we use a mixture of hydrogen peroxide to soften the seed’s outer skin. It would be best if we were careful when mixing the peroxide solution, as we can burn the seed, and it will never germinate.

The second method involves the use of carbonated water with a pH below 7. This slightly acidic solution absorbs the outer layer of the seeds. Put the seeds in a container full of carbonated water and wait for about two hours. The solution loosens the seed coat and allows it to absorb water, which helps germinate.

In addition to chemical and mechanical scarification, we can use other DIY methods to loosen seeds. For example, we can use a small knife to scratch or open the seed coat. We can explore different approaches as long as we do not damage the seed embryo.

The first step in any farming process is to make sure we have the right seeds, and the same goes for weeds. When harvesting autoflowering marijuana seeds, everything is preserved, and nothing is lost. This means that all types of seeds are ripe and immature. How do we distinguish good seeds from bad ones? You are considering the following.
