Make a hole in the growing medium that is about twice as deep as the seed is long, so that each germinated cannabis seed sits 2-5mm below the surface.
Place another few layers of moist tissue on top of the seeds, again allowing excess water to drain off.
Lastly, cover everything with the second plate, upside down, to form a ‘clam-shell’ shape – this will create the dark, moist environment necessary for germination.
Step 3. Potting – How to germinate cannabis seeds
This article explains how to correctly germinate your cannabis seeds, covering everything from optimum temperatures, to potting your seedlings and transferring them outdoors (or inside under lights).
Seedlings intended for outdoors should be acclimatised to direct sunlight by placing them on a windowsill inside the house and increasing their exposure to direct sunlight by an hour or two per day.
Unfortunately, regulation and implementation in respect of cannabis seeds often differ from country to country. For this reason we advise you as a matter of urgency to make inquiries about the regulations to which you are subject. Read the complete disclaimer here.
Cannabis seedlings usually emerge from the growing medium 24 to 72 hours after the germinated seeds are planted.
You can jump start the process by putting seeds in a jar of water for 24 hours and soaking them.good seeds will sink, bad seeds will float. To get started, put some seeds inside two moist cotton pads. Check the bowl on a regular basis if it is still humid enough and if the weed seeds already start to burst.
Pull the cotton wool apart slightly to break up the fibers a bit. Germinating cannabis seeds in a cup of water. Germinating cannabis seeds is easy, if you use a cup of water says our scribe, matt mernagh.
In this step you’ll need two ceramic plates.
If you wish to germinate marijuana seeds in rockwool, you must add fertilizer beforehand. Some breeders prefer to germinate their seeds in the dark so they put the cotton wool pads in between two saucers, you can try this but it is not necessary. For this guide, we will be using kitchen towel as it is readily available and holds moisture relatively well.
Marijuana seeds typically germinate within a few days in rockwool cubes. We do this with the utmost care. Sprinkle water on one side of the cotton wool and make sure it reaches all your seeds, then fold the other half over them.
To germinate seeds of marijuana securely, put to soak your seeds of marijuana a few hours before, and in a tupper, places a base of wet napkins, without they get to soak, distribute the seeds above and cover them with other napkins in the same way. Rockwool is an excellent medium for cultivating cannabis. Before starting this, you can soak your “beans” in a cup of filtered or distilled water for 12 to 24 hours to maximize your germination success rate, but we will get to this part a bit later.
It’s good to know that a cannabis seed doesn’t need light to germinate, only a humid environment. Light is only important for the cannabis seed when leaves arrive, because they absorb the light. Until then, it doesn’t matter if the light is dark.
The moisture in the cotton wool or toilet paper evaporates fairly quickly at room temperature. It is important that the seeds remain moist during the period that they have to germinate.
The moisture in the seeds activates the seed and starts germinating.
If necessary, you can cover the cannabis seeds with a piece of damp toilet paper and place a reversed saucer on top.
Cannabis seeds germinate on a moist surface
Before you can start growing weed, you must first germinate the weed seeds.
In general, there are three ways of germinating cannabis seeds:
Every plant knows it has to grow upwards. So it is also possible to put the cannabis seeds directly into the soil. The chance that marijuana seeds will germinate in this way is slightly smaller than with the other ways.
Place the cannabis seed on a surface that retains moisture. This can be done for example on cotton wool or toilet paper on a saucer, make the surface well moist, but be careful not to get too wet.
