I ordered 5 fem nightshade seeds from barneys, 2 of them didn't even germinate, and the three that were left were ALL hermies... but guess what... Rather than assume that one of the most popular and well established breeders is perpetrating a fraud and somehow managed to fool all the people, breeders and high profile growers alike, who give them respect, I chose to assume that my growing techniques have a lot of room for improvement. Ya know, Occams razor and all.
I simply got a bottle of reverse, sprayed them twice, and never saw male flowers again. Those three plants yielded nearly 9 OZ, with two seeds found.
