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.
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.
1. PRE-SOAK WITH SUPPLEMENTED WATER
Removing the ridge not only makes it easier for the seed to open, it helps with water absorption.
The seed’s shell is made up of two pieces, with a seam going all around. The side that’s raised more than the other is the ridge. A hardened ridge can make it difficult for the seed to open. To remove the ridge, run a sharp blade along the ridge on both sides. Handle gently and it should come off without damaging the inside of the seed.
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.
Now simply maintain a good hydration and stable temperature, leaving nature to run its course. The fundamental advantages of coconut substrate, is that they allow a greater root growth than other types of substrates, and collect moisture very well, your seeds will grow and become larger plants and therefore with higher levels of productivity.
When your marijuana plant has already germinated, you must pass it already to plantation. Be patient, because during the first week you will see practically no progress, but from then on, the events shoot at a crazy speed.

The ideal lunar phase to germinate your marijuana seeds according to the lunar calendar, is the Fourth Increasing phase. During this stage the moon increases the power of its rays, to which the plants respond with increased foliage and root. The end of this stage is the perfect one to germinate your seeds, thus you will begin to plant it the first day of full moon.
A very easy and useful process, is to put the seeds in a glass of water and let them rest until you see that the root begins to come out, when this happens and very carefully, you can transplant them without introducing them very deep into the ground, allowing them to come to light.
All these rooting systems can be purchased in your trusted Grow shop and do your own tests to see which method works best for you personally, since as we have indicated only three of the forms of germination of cannabis seeds … and as they say out there, “every teacher has his booklet”. ?

Marijuana germinates best at room temperature, around 72° F in a consistently moist environment. The first visible sign that a seed is germinating is a slight enlargement resulting from water absorption. Then a small opening appears along the seed’s seam as the root emerges. The root continues to elongate, growing downward, as the stem makes its appearance. It stretches out in the opposite direction of the root and uncurls, revealing two embryonic leaves called cotyledons. The seed case is now an empty shell and it may hang from one of the cotyledons until blown or rubbed off. Only a day or so has elapsed between the first sight of the root and the appearance of the cotyledons.
Methods for germination

In its first phase of growth the seedling used energy stored in the seed, but it must soon use photosynthesis to produce its own food as its roots supply moisture and nutrients The root grows longer and lateral branches grow from the vertically growing tap root. The first set of true leaves emerge at the tip or apex of the stem, which is called the apical tip.
After soaking you can place the seed between a thin wet cloth or paper towel on a plate with a clear cover or plastic wrap. When the root emerges, plant it by first poking a hole in the planting mix that is long enough for the entire root area to be covered. Then gently place the seed and pat it so the root makes contact with the medium. The other method is to plant the soaked seed into the medium before it germinates. Place it ¼ inch deep in sterile commercial planting mix. Moisten the mix with water adjusted to a pH of around 6. Keep it in a bright space with high moisture. If the space is dry, place a tall cover over the container to reduce evaporation. Keep at room temperature. If the air is cool, use an electrical tray warmer and cover.
