How To Germinate Old Cannabis Seeds

We can only expect to use the old seeds with the cost of seeds floating above potheads’ reach. However, improper or long-term storage of seeds can cause infertility – and they cannot germinate. However, how do we let those old cannabis seeds come to life again? This guide will help us convert the relics into a sea of green sections of robust cannabis fields!

Sorting Old Cannabis Seeds

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.

Sorting Seeds By Color And Shape

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.

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.

Classification Of Seeds By Hardness

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.

Ways to Germinate Old Cannabis Seeds

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.

Method 1 – Scarification

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.

Method 2 – Carbonated water

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.

Method 3 – Mixture of hydrogen peroxide

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.

  • One part 3% hydrogen peroxide with six parts water.
  • One part 4.5% hydrogen peroxide with nine parts water.
  • One part 6% hydrogen peroxide with 12 parts water.
  • One part 30% hydrogen peroxide with 60 parts water.

Always Use Clean, Fresh Water

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.

Conclusion

Old cannabis seeds sometimes pose a challenge for germination. You can sort ripe seeds, release the hard protective layer by various methods, try new chemical germination enhancers, or use biocatalysts. Similarly, soaking the clean, soft seeds in clean water will push the embryo out of its protective blanket. After trying some of the above processes to germinate the old cannabis seeds, we can be sure to grow healthy and living plants and expect good yields.

Here’s How To Germinate Old Cannabis Seeds

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.

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.

BEFORE YOU START, SET YOUR EXPECTATIONS STRAIGHT

Before you start, it’s important you remember the following:

• 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.

• 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.

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.

To help older seeds along, it’s a good idea to try scarring them. To do so, simply line the inside of a matchbox with some fine sandpaper, place your seeds inside, and shake the box for a minute or so. This will help make some small cuts in the seeds’ outer shells to help them absorb some moisture.

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.

TRY GERMINATING YOUR SEEDS IN CARBONATED WATER

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 “THE PAPER TOWEL METHOD”

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:

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.

LET MOTHER NATURE DO HER THING

Sometimes, it’s best to leave Mother Nature to work her magic on your old seeds. Try scarring your seeds a little as we showed you earlier, then let them sit in carbonated water overnight. Next, prepare a small nursery pot with some high-quality soil. Make a small hole in the middle of the pot with your finger, roughly the depth of your fingernail. Drop your seed inside the hole and cover it. Moisten the soil and keep your pot in a warm place with indirect sunlight—a windowsill works great.

REMEMBER TO STORE YOUR SEEDS PROPERLY

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:

• Seeds like cool, dry, and dark places.
• Quick changes in temperature and humidity are really bad for seeds. Try to keep them in a jar or other container to protect them against these environmental factors.
• Seeds don’t like light. Keep them in a dark place and avoid any unnecessary exposure.
• All of our seeds are vacuum-sealed. For the best germination rates, only open a pack of seeds when you’re ready to plant them.

5 Tips For Germinating Old Seeds

Here are some good tips for germinating seeds that are hard to start or are having trouble germinating. Have some patience though as it could take anywhere from three days to three weeks for a seed to germinate. Some of these tricks I would only use if the seed has not sprouted after two to three weeks or if you have a few seeds in reserve from a batch that haven’t germinated.

Seeds are comprised of an outer hard layer and an embryo which is inside the hard shell. The reason that older seeds don’t germinatem well is that the shell has become to hard and water is unable to penetrate, this process of imbibition is the start of the germination process. The seed will swell with water and eventually the shell will pop open and a small tap root will erupt.

One thing i wouldn’t do is to germinate your seeds on a paper towel. White paper is filled with bleach and other chemicals and is not a good thing for your plants. Use small jiffy starter blocks or a light soil:

1. Dilute 10ml (roughly one tsp) of Fulvic acid per litre (33 oz) of water.

2. Scuff the outer shell of the seed with some sand paper. Roll up a small cigar or sand paper or line a match box and gently shake the seeds over it. This will create micro abrasions letting in more water.

3. Use a lightly carbonated water. The extra Co2 will help the water penetrate the seed.

4. Use a light enzyme or seed booster, Plagron Nutrients has a very good one.

5. Finally if all else fails use an Exacto knife to slightly slice the seed open down the spine of the seed. This will make it easier for water to penetrate the shell.
