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 auto-flower 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 temperature. When the whitetail appears, plant your seeds 1/2 inch deep in the 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)
