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)


Introducing Double Stack Female Cannabis Seeds by Compound Genetics, the latest addition to their exceptional feminized strain lineup. This remarkable strain is the result of crossing the beloved Apple Fritter with Compound Genetics’ renowned classic strain, Jet Fuel Gelato.

Double Stack inherits the best traits from its parent strains, resulting in a robust and high-yielding cultivar. With a THC potency ranging from 25% to 27%, this strain delivers a powerful punch. Its average plant structure produces dense buds that showcase an alluring combination of green and purple hues.

Prepare your senses for a delightful experience with Double Stack. It offers a unique blend of mild sweet fruit terpenes, complemented by distinct notes of spice and Gelato. You’ll also discover a complex profile with hints of tart fruit and baked goods, creating a truly flavorful and captivating variety.

Double Stack is a high-yielding strain that will impress cultivators of all skill levels. Whether you prefer indoor, greenhouse, or outdoor cultivation, this versatile strain thrives in any environment. The flowering period ranges between 8 and 10 weeks, with some phenotypes potentially extending to 10 weeks. However, thanks to generative irrigation in weeks 7 and 8, most phenotypes will finish within the earlier time frame.
