Planting cannabis seeds indoors

Soil is an easy, more natural method with which to germinate your cannabis seeds. The soil protects the fragile roots from any interference, and soil is, after all, where a cannabis plant would grow in the wild.

How to germinate cannabis seeds

Gently water the soil with a spray bottle and situate your pots under a fluorescent lamp. Keep seeds away from the windowsill, as the temperature is too volatile for germination. In general, you’ll want to keep the temperature in the range of 70 to 80 degrees Fahrenheit.

What is germination?

The seeds should start sprouting in about two days, though older seeds can take up to a week to sprout. You can remove them from the water and place them in the soil at any point once they’ve sprouted. Once the roots are about five millimeters long, they need to be planted.

After the harvest, the tasting will allow us to choose the best female according to our criteria (taste, smell, effect, yield, resin production, resistance to pests, etc.) and keep them as mother plants, so we can grow the same plant again and always with the same traits. Indeed, regular seeds are the perfect option for selecting mother plants.

Keeping the temperature between 20 and 25° C, 100% of the seeds sprouted within 48 hours. They were planted into 3 litre pots during approximately 3 weeks of growth. It?s possible to use smaller plant pots during the first days of the plant’s life to create a more dense and effective root system.

During the end of the flowering satge, when plants come to the end of their life cycle, we will use only water – without fertilisers – to perform a more rigorous root flushing. The chlorophyll breaks down and the plants lose their green colour: if carotenoids predominate, the plant will turn into yellow colors, but if the anthocyanins dominate – a natural pigment present in blue varieties which appears due to low temperatures as a protection from the cold) the marijuana plants will turn into a beautiful purple/bluish colour.
