How to sprout weed seeds in water

– On a damp surface

Germinating cannabis seeds in a cup of water

Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or at least not optimally germinate. Use a clean room and area for the germination process. Fill a cup with water and put the cannabis seeds in it. After 3 to 5 days, the seeds should pop open and a tiny root should come out. As soon as the sprout is 2 to 3 mm, you can carefully get the seeds out of the water and plant them in the soil. Planting the germinated seed has to be done with lots of care and attention. Put them 0.5 to 1 cm in the soil with the root down. This way, the root (the white sprout) will more easily grow downwards.

Germinating cannabis seeds on a damp surface

Maintain an ambient temperature of at least 20 °C, otherwise, the seeds will not or at least not optimally germinate. Put the cannabis seeds on a surface that holds moisture, like wadding, paper towel or tissues on a saucer. Moisten the surface well, but avoid making it too wet. The moisture evaporates quickly at room temperature, so check during the period that the seeds will germinate if the surface is still damp enough. You can also cover the seeds with damp wadding or tissues and another saucer on top. Because of the moisture that gets into the seeds, they are activated and start to germinate. As soon as the germ is 2 to 3 mm, you can carefully get the seeds out of the water and plant them in the soil. Put them 0.5 to 1 cm in the soil with the root down. This way, the root will more easily grow downwards.

It is a simple method, but also a risky one. You could damage the taproot while moving the sprouted seeds, or else the paper could dry out and kill the seeds. In any case, here is the process:

Turn on your grow light once you have planted the seeds. The heat improves germination rates and speeds up the process of the seedlings opening their first set of leaves. These leaves will remain yellow until exposed to a sufficient level of light in any case. When you plant multiple seeds, you will find that they grow at different rates.

1 – The Paper Towel Method

Your seedling should instantly adjust to the new environment and grow. When using this method, dig a hole 0.5” – 1” deep in soil that is moist but not saturated. Keep things warm with a heating pad or lighting.

This is arguably the trickiest aspect of germination. You have to strike a balance between ‘warm’ and ‘hot.’ Spring temperatures are ideal in a ‘normal’ year. While cannabis seeds can germinate in colder weather, the process takes longer. Seedlings also germinate faster when there is plenty of humidity in the air. If you are concerned about low temperatures, invest in incandescent bulbs, and place them over the seed area.

Transplanting Germinated Cannabis Seeds

This is as simple as option #3. It involves nothing more than placing the seeds in a glass of lukewarm water overnight. It is a good idea if you’re using old and hard seeds. The soaking process can breathe new life into them. When you place the seeds in water, they float for a few hours before sinking to the bottom.
