i read in a book by jeff ditchfield that if you put a conticeptive pill in water and desolve it then drop your seeds in there is a better chance of them becoming female... bit far fetched but he knows what he talking about... the book is called cannabis cultivator by jeffery ditchfield... great book btw.
I used to know Jeff when he ran BudBuddies and the Welsh coffeeshop, can't remember what it was called now? Hes a good guy and knows his cannabis and has done loads for the pro legalisation cause.
Personally I wouldnt bother with that tip though, but hey.who knows
!
Heres another tip though..... a few years back we experimented with 12/12 from seed/germination grows and agreed that the % of females to males went up considerably on average, averaged 7/8 out of 10 as opposed to a round the 50/50 mark one might normally expect to achieve. On one occassion growing Tutti Frutti 12/12 from seed ( a Blueberry cross) I personally experienced 8 from 10 females/males.
Anyone got any thoughts/experience on this one?
I still do it with my Kush strain and rarely see a male this way.
Give it a try maybe. dont stress them; when they germinate put them in a deep container so you dont need to repot in a couple of weeks.
