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.

• 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.

• Seeds can take a while to germinate. While healthy, fresh seeds can germinate in just a few days, old seeds can take anywhere from 2 days to 3 weeks to sprout. So be patient.

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:

LET MOTHER NATURE DO HER THING

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:

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.

Try dropping your old seeds into a glass of sparkling water. The CO₂ in the water should help the seeds absorb more moisture, encouraging them to sprout. You can also add some fulvic acid to the water to help break down the shell of your seeds. You’ll only need about 2.5ml of acid for a glass of sparkling water (roughly 250ml).

TRY SCARRING YOUR SEEDS

One of the main reasons old cannabis seeds don’t germinate is because they tend to have a very hard outer shell. Now, cannabis seeds naturally have a hard shell that helps protect them until the conditions are right for them to germinate. Over time, however, this outer shell can become so hard that it inhibits the seed from germinating altogether.

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.

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.

To use a mixture of hydrogen peroxide for the germination process, use 1 to 2 drops of 99% hydrogen peroxide in a glass of water. After soaking for 24 hours, the outer shell is softened enough to germinate the seeds.

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.

Method 2 – Carbonated water

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.

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.

Whether we obtained the seeds from a seed bank, a store, or a retailer, different cannabis seed strains have different colors. Mature cannabis seeds acquire a dark coat, while immature ones are brighter and usually white. The most visible colors are brown, tan, and sometimes black. In contrast, bright yellows and whites quickly identify immature seeds.

Method 3 – Mixture of hydrogen peroxide

Although the seeds have taken some time inside storage containers, ripe weeds seeds’ hardness is not compromised. Hard and tough seeds with a smooth shell guarantee a reasonable degree of germination. Also, pay attention to wavy and cracked seeds. They will lose time and energy and will not germinate after planting.

Clean and clean water contains oxygen and hydrogen molecules. These are two life-supporting elements necessary for germination. Soaking the seeds for at least 12 hours allows water to enter living cells, a process known as osmosis. Now that the internal conditions promote germination, the semen embryo expands and breaks out of the protective sheath.

The feel of cannabis seeds is another good indicator. Hold the seed between your thumb and forefinger and give it a light squeeze. Don’t apply too much pressure – just enough to test its integrity.

Another type of bad seeds is male cannabis plants. There’s a 50/50 chance with regular seeds as to whether any given seed is male or female. The problem is that male plants will pollinate the females once they reach maturity, destroying the valuable THC content of female plants.

Method #1: The Sight Test

One way around this is to purchase feminized marijuana seeds. In theory, all seeds in a feminized bunch will be female – unless you buy from a disreputable grower. Unfortunately, there’s no way to tell whether a plant is male or female simply based on the seeds.

Telling good and bad cannabis seeds apart is not an exact science. Sadly, you don’t know what’s inside the seed beyond its appearance, so you won’t know what the plant is truly like until you start growing it.

What Makes a Cannabis Seed ‘Bad’?

Sometimes, you can end up with ‘bad’ cannabis seeds that will cause problems later down the line. In some cases, these seeds just won’t germinate. Although this won’t ruin your entire crop, it is a waste of time and money, which can be frustrating.
