I recommend checking out this website if you are looking for a specialized store selling cannabis seeds: https://kindseed.com/ It offers a selection of seeds for various purposes, from collecting to growing where it is legal. The varieties are grouped by type (regular, feminized, autoflowering, indica, sativa, hybrids), so even without much experience, it is easier to choose an option with the desired characteristics, whether it be yield, growth rate, or effect. I would advise you to carefully read the descriptions of the varieties before ordering, check the legal restrictions in your country or region, and not chase after the “coolest” characteristics, but choose easier-to-care-for options if you have little experience.
