they say 50/50 but i don't think its accurate for the majority of indoor grows. I planted 7 bubbilicious and 4 kush, all though kush arent in flowering yet, I only got 2 females from the seven.....well actually 50/50 may be accurate b/c i just realized i am just a bit over 30% w the 2 out of 7, now if atleast 2 of the 4 kush turn out female i would be within that range. So i correct myselof i think probably for the norm you could on average suspect a 50/50 outcome
