Untill now… it’s only possible to grow female seed ( so not : feminized ) with the right dose of Gibberellic Acid.
Read the first edition of the growers guide from Mel Frank !( before he did make action with the money devil Ed Rosenthal)
Mel Frank told us already in 1969 that it must be possible to do it with GA. He also wrote : It didn’t work out for me but it must be possible.
But it’s hard to do it succesfull.
It did work for me… but only 1 or 2x per year.
Stay cool, SpeesCees
