Choosing seeds

Feminized seeds
When given less than 12 hours of light every day, feminized seeds bloom and produce weed. Gather either in the fall outside or indoors after around 15 to 20 weeks. Feminized strains are used by beginners & experienced growers and produce higher quality buds than auto flowering strains.

Automatic seeds
Easy to grow and simple plants can be cultivated from autoflower seeds in just 10 to 14 weeks before they are ready to be picked. Fantastic for first-time cultivators, limited harvesting areas, and seasonal yields.

How to germinate

To ensure germination, immerse the seeds in a glass of water for at least 12-72 hours while keeping them in the dark at room temperatures. When the white tail appears, plant your seeds 1/2 inch deep in soil or another medium that has been moistened. You should see a seedling emerge within 2 days after planting. Seedlings thrive in bright, sunny conditions (21°C to 23°C)

This cultivar is mostly indica and with THC levels between 5% and 8%, while its CBD level is between 8% to 12%. Critical Mass feminized cultivar hails from very potent genes of weed that can knock you off with just a blow.

This herb could be used for medical purposes, especially as a sedative. Recreational smokers are also at the benefit of the sedative effect of this strain. Even better, they enjoy Critical Mass more because of the sweet fruity aroma it burns with.

When it is time to harvest, the seeds of Critical Mass feminized cannabis cultivar produce a generous yield. Regardless, when grown in optimum condition, it completes its flowering time in 8 weeks to 9 weeks and produces up to 550 grams of weed per square meter indoors and 600 grams to 750 grams per plant outdoors.
