ETHOS, Twenty20 Mendocino, Mephisto, Sweet Seeds, Humboldt..
The real humboldt not the HSO (Humboldt seed organization) but Humboldt Seed Co
Pretty simple rule of thumb - if they offer much more than 50 different strains of autos - then they are a reseller. Not a breeder, and they really have no idea what they’re selling you. They just bought it in bulk to sell to you. These are white label seeds. Bought wholesale.
If you aren’t sure about a particular company- feel free to DM me. But the ones I suggested are excellent genetics.
