Is this plant too late into flower (week 3?) To begin ga3 treatment for self pollination? I can't tell if the 10 days MUST be before flower or before week 4 of flower.
I have a very small clone I could use for the purpose as well.
First of all, I could be wrong but I don't think credit should go to Van Dalen. There are research papers out of India from the 70s and early 80s demonstrating sex reversal with all of these compounds.
As for the genetics of producing feminized seed, it will really depend on how you proceed. Selfing a plant will lead to genetic erosion, but crossing with feminized seed not so much.
