germinating cannabis seeds in light or dark

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.

Cannabis seeds require a specific temperature range in order to germinate. Regardless of the germination medium you are using (soil, paper towels, etc.), the temperature in the environment should consistently sit in the 26–28℃ range. Seeds need to be kept warm during the germination process. At no point during germination should seeds be exposed to temperatures below 20℃.

TOO MUCH LIGHT

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.

Many people choose to germinate their seeds using paper towels. However, others choose to do so directly in soil. Of course, germinating your seeds in soil isn’t inherently bad, but it can come with its own set of challenges, and is generally not recommended unless necessary.

The amount of water you supply your seeds during the germination process will also affect their ability to successfully germinate. Some growers attempt to germinate by “drowning” them in a glass of water. While this ensures they will not go thirsty, it can actually be more harmful than helpful.

Want good cannabis? Get good seeds!

We cannot stress this enough. If you want good results, you are going to need good materials to start with. In case of growing cannabis, the first thing on that list are good cannabis seeds, of course. Besides high quality cannabis seeds all you need is some water, a warm environment (between 20-25 degrees Celsius) and – lack of – light to start germinating your future cannabis plants.

How To Germinate Cannabis Seeds, Step 1: Get Good Genetics

Germination is actually a process where you activate a dry seed that is in a ‘sleeping state’. By adding water to the seed, a small root that is inside the seed-shell will want to come out in search for more water. This will make it develop into a big taproot that’ll serve as an anchor for the plant and from which more roots will sprout.

Even though living weed plants love (and need) a lot of light, germinating cannabis seeds thrive better in a dark environment. And just like there are different methods of growing your own cannabis, there’s also a choice in how to make your seeds sprout.

By planting cannabis seeds directly in their soil or coco – or whatever other medium you might be using – growers cause the minimal amount of stress for the plant. Direct planting also allows the taproot to immediately dive as deep into the ground as possible. Furthermore, its leaves can enjoy the light as soon as they emerge from the developing seed. This way the seedling can start its growth with a fair chance, providing you with a steady, high-yielding cannabis plant.
