Seed Type

Feminized Cannabis Seeds

Feminized seeds are genetically bred to grow only female plants – the kind that produce resinous, cannabinoid-rich flowers. These seeds eliminate the guesswork, allowing growers to focus on yields, potency, and quality without the need to identify or remove male plants.

  • 100% female – no risk of accidental pollination
  • Maximized efficiency for hobbyists and professionals
  • Stable, consistent, and optimized for flower production

Autoflowering Seeds

Autoflowering seeds begin flowering automatically after a few weeks, regardless of light schedule. These varieties are perfect for fast, compact, and low-maintenance grows – making them ideal for beginners or limited spaces. Despite their speed, modern autoflowers can deliver impressive potency, aroma, and structure. We offer advanced autoflower crosses that combine performance with rich terpene expression.

Classics

Our Classics represent proven strains that have stood the test of time. Known for their stability, yield, and unmistakable aromas, these cultivars form the backbone of modern breeding. Whether you’re looking for reliability, nostalgic flavor, or a trusted starting point for your grow – Classics always deliver.

Fast Flowering Seeds

Fast flowering photoperiod strains are designed to finish blooming quicker than standard varieties – often 1–2 weeks earlier. This makes them ideal for outdoor growers in shorter seasons or for efficient crop rotations indoors. These cultivars retain all the flavor and potency of classic strains, but with a significant time advantage.

Regular Seeds

Regular seeds are unmodified cannabis genetics that produce both male and female plants. They’re the foundation for breeding and pheno hunting, allowing growers to select strong mothers or develop new lines. Regular seeds offer full genetic expression and are favored by those who value authenticity, stability, and long-term selection work.

Landrace Seeds

Landraces are original, indigenous cannabis varieties from specific geographic regions such as Afghanistan, Colombia, South Africa, or Thailand. These cultivars have adapted over generations to their local environments, resulting in unique growth patterns, effects, and terpene profiles. Landraces are prized for their diversity and purity – offering a direct connection to the plant’s genetic roots.
