how long to soak old cannabis seeds

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.

Scarification, or scuffing the shell, can also help water pass through an older seed’s tough outer shell.

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.

3. REMOVE THE RIDGE

As cannabis seeds age, their protective outer shell hardens and prevents water from passing through. Unless the tiny, dormant embryo that lives inside the shell detects moisture, it doesn’t know that the conditions are right to sprout. As a first step, pre-soak your old cannabis seeds for about 12 hours to see if that does the trick.

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.

When your old cannabis seeds don’t want to pop, one of these four techniques could come to their—and your—rescue. Aging seeds are more difficult to grow than fresh ones and we’ll explain what you can do to help germination.

Keep the water warm, but not too hot. Aim for around 22°C. Avoid direct sunlight, and keep an eye on the glass. Do not soak seeds for prolonged periods, more than 24 hours can deprive them of oxygen and make them drown.

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.

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.

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.

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.
