We are the ultimate source of quality cannabis genetics that produce excellent marijuana strains.



Purple Diesel (East Coast Sour Diesel X Purple Punch) Cannabis Seeds
Purple Diesel feminized seeds are a rarity and descend from breeding a variety of respected cultivars. East Coast Sour Diesel (ECSD) and Purple Punch join together despite their polarizing mental effects to create pleasantly unexpected experiences. ECSD jacks you into high energy while Purple Punch soothes the body. With strong parents like Purple Punch and East Coast Sour Diesel (ECSD), Purple Diesel’s feminized seeds provide a great experience for anyone hunting for relief from pain, stress, depression, anxiety, and nausea.



No one comes close to our quality in genetics. We don’t source our seeds from overseas and repackage them as many other online cannabis seed banks do. As a US cannabis seed bank, we only sell cannabis seeds that we have created. Many other marijuana seed banks only sell seeds from other breeders. The seed banks themselves have never grown or tested the products they sell. We put all of our genetics through intensive testing, season after season, to bring you only the best cannabis seeds available.
