these seeds were donated to my collective by a breeder named hemlock from breeders boutique. (Breeders Boutique) Clones cost next to nothing to make, (at most 10 bucks per 100) and clubs and patients buy up clones like candy. I get more donations from clones then i do for flowers. so to answer that question, i dont pay for seeds or clones. Because I am growing for a good cause (disabled veterans) many people and companies make donations and it all works out. All my gear has been supplied by the collective and outside people.
As far as 1-2 plants in a scrog, since I grow for many patients who dont all have the same needs, I try to always have at least 10 strains running. Realistically I have about 20-30 strains at any given time. I regularly test new breeds out and see how they turn out, but I have the core strains my patients and I love.
