do weed seeds need light to germinate

But you don’t need any propagator at all.

All you do for this method is poke a hole in the soil or growing medium that is about half an inch deep (1.5 cm). Place the seed in the hole and cover it up. Ensure that the soil or growing medium is moist, but not soaking wet. The temperature needs to be in the correct range as well.

Pros
very easy
no additional equipment required (assuming you have paper towels)
Cons
requires transplanting the seeds, which risks damage
need to ensure the paper towel stays damp, but not wet

If you do not have a grow light, there are a number of different types you can consider. For seedlings, fluorescent lights or LED light bars (like the veg/clone bars from Secret Jardin) are ideal, unless you are germinating a lot of seeds at once. Then you might want to consider a larger Plant LED grow light.

Seeds that have been improperly stored may also fail to germinate. These tiny packages of DNA prefer to be kept in a cool, dark place with moderate humidity. Exposing them to heat, light, or extreme humidity levels (both high and low) could result in seeds losing their viability. As long as you source your seeds from reputable seedbanks and store them appropriately, you shouldn’t have to worry about bad seeds ruining your chances of successful germination.

Once they pop, seedlings are very delicate and must be watered carefully. When germinating, your medium should be damp, but not overly wet for best results. On the other hand, a dry environment is basically a death sentence for your seeds. They need a constant source of moisture to sprout, otherwise they’re good as duds.

TOO MUCH LIGHT

Generally speaking, seeds require a dark environment in order to germinate. After all, in nature cannabis seeds find their home in the dark embrace of soil. It can be hard to determine exactly how much light is too much for your seeds; however, err on the side of caution and germinate out of direct light. There’s no need to use your grow lights until after germination has occurred.

There are some techniques that can be used to ensure your seedlings remain in this temperature range. Some growers choose to use special warming mats that can be set to a specific temperature and placed underneath the seedling containers. Another strategy is to place a timed heater close to your seedlings to warm them up occasionally. Once your seeds have sprouted, they will be much more resilient to fluctuations in temperature.

For instance, the upper layer of soil can dry out within 48 hours, making it more difficult to give your seeds the right amount of water they need without overdoing it. Giving your soil too much water during germination could result in the seed rising up or dropping down further, inhibiting its viability. Moreover, seeds that are planted too deep in the soil could experience a host of complications. They could suffocate before coming into contact with enough oxygen, and be unable to access sufficient light to progress into the seedling stage of their life cycle.

Ensure an ambient temperature of at least 20 degrees, otherwise the seeds will not germinate or will not germinate optimally. Fill the cup with water and put the cannabis seeds in it.
After 1 to 3 days the weed seeds should pop open and show the carrot.
If this is the case you can put these germinated seeds directly into the soil. Then put them about 1 to 7 millimeters into the soil with the root down. The stem that comes out of the cannabis seed after germination is not the plant, but the root! It is best to point this little stem downwards when planting the germinated seed. This way the plant will find its way down easier, this is not a must, but a tip.

Before you can start growing weed, you must first germinate the weed seeds.
In general, there are three ways of germinating cannabis seeds:

After the carrot has emerged from the seed, it is ready to be put into the soil.
Cover the pot with a piece of transparent plastic, this way you actually make a small greenhouse with high humidity, young baby plants love it very much.

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.
