germinating very old marijuana seeds

In a life or death situation, surgery may be the only option. Meaning—only do this if nothing else has worked because this technique ruins as many seeds as it saves.

If you’re going to keep seeds more than a year or two, proper storage will dramatically increase the chances of late-stage germination. Place them in an airtight container. Put the container in a refrigerator set at 6–8°C with 20–30% relative humidity. If excess moisture is a concern, add silica gel packs to the container.

The older a cannabis seed gets, the harder it is to pop. But hard doesn’t mean impossible. If you’ve been saving your seeds for a rainy day and it finally started pouring, these tips could help you get most, if not all, of your old beans to germinate.

4. SLICE THE SEED

As you proceed through these steps, the risk of damaging your seeds past the point of recovery increases. Between each suggestion, give them a few days to a week to germinate. Allow the outside to dry each time to prevent rot. Do not try all or multiple techniques at once.

To scarify your seeds, line a matchbox or other small container with sandpaper. Drop the seeds inside, shake vigorously for 30–60 seconds, then remove. You may not notice much of a difference, but the small micro-abrasions are sometimes enough to let water breach the shell and trigger germination.

Removing the ridge not only makes it easier for the seed to open, it helps with water absorption.

To improve your chances, use carbonated water and/or add one of these supplements that help with water absorption. Fulvic acid and most boosters also give your seeds a light dose of nutrients.

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).

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

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 “THE PAPER TOWEL METHOD”

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.

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.

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.

• 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.

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.

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.

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 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.

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!

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.
