Buy Cannabis Seeds Online

StrainSupermarket® is built to give growers a clear, organised way to explore modern cannabis genetics without unnecessary complexity. Our goal is to present each product category in a way that reflects real differences in how seeds grow, how they perform and what each type is best suited for. Whether you are new to growing or refining a more advanced setup, this guide offers a simple way to navigate our range.

How Our Cannabis Seed Categories Work

All of our cannabis seeds are organised into focused categories that help you quickly identify the genetics that match your growing environment, timelines and preferred effects.

Feminized, Autoflower & Regular Seeds

Our feminized cannabis seeds category includes stable, female-only genetics chosen for reliable performance and strong yields. These strains suit most indoor and outdoor environments and remain the most popular option for growers of all experience levels.

For a faster, simpler life cycle, our autoflowering cannabis seeds combine modern potency with predictable development and discreet, compact structure. They are ideal for growers seeking speed and ease of use. For those exploring breeding or classic-style growth patterns, our regular cannabis seeds provide both male and female genetics for full control.

Fast-Version, High-THC & CBD Genetics

Some projects benefit from shorter flowering times. Our fast-version seeds offer accelerated flowering while maintaining photoperiod control, making them suitable for short outdoor seasons or increased indoor harvest cycles.

For growers focusing on potency, the High-THC cannabis seeds range highlights elite strains known for strong cannabinoid levels, pronounced terpene expression and dense resin production. If you prefer balanced or non-psychoactive effects, our CBD seed selection offers gentle, versatile genetics suitable for a range of preferences.

Variety Packs & Value-Focused Categories

If you want to explore multiple strains at once, our variety packs provide an efficient way to try different genetics in a single purchase. We also maintain dedicated value-driven options, including buy-one-get-one-free seeds, clearance seeds and special-offers for discounted or limited-time promotions.

A Store Designed for Growers

StrainSupermarket® is structured to help you compare genetics easily and move with confidence toward the strains that fit your goals. Each category has been arranged to provide clarity, reduce guesswork and support better decision-making—whether you prioritise speed, yield, flavour, potency or overall plant structure.

Responsible Growing
