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)

*Please Check Legality In Your Own Region.


The resulting hybrid is 75 percent Sativa, yet it does not generate an overwhelming cerebral high due to its CBD level, which can reach 7%. When you add in the 12 percent THC, you get highly sought-after cannabis that can help with a variety of medicinal problems like anxiety and pain. It does, however, have excellent qualities as a recreational ganja.

It energizes the body and awakens the intellect without causing any negative side effects. Harlequin, which was previously only available as a clone, can now be easily cultivated at home with these feminized seeds.

Harlequin’s smoke is thick and smooth, and it isn’t notorious for making people cough. It has a seductive aroma of creamy vanilla, luscious mango, and earthy notes. As strange as the combination may appear, it is undoubtedly a flavor you will remember for a long time. 

With a flowering period of 8 to 10 weeks, it produces 550 gr -600 gr m2 indoor and 800 gr. plant outdoor

    Sprouted and grew extremely well in an inside grow tent. I pinched leader branch at 5" and it grew like an autoflower. The plant was very short but packed with big buds. Then, tragedy struck. I took my plant outside to finish off and it got massive bud rot. Moral: this variety needs low humidity and better for me to grow indoors. I'll try again.
