-Temperature: Low temp increase the number of female plants. Warm temp makes more males.[I know this first hand having turned 9 plants into males]

-Humidity: High humidity iincreases the number of female plants. Low humidity increases male plants.

-Light Spectrum: More blue light incereases the number of female plants[MH]. More red light increases male tendencies[HPS].

-Photoperiod: Fewer hours of daylight(e.g. 14 hours) increases the number of females. Longer days (e.g. 18 hours) make roe male plants.[think of all those people on 24 days]

Stress: any enviromental stress tends to yeild more male plants when growing from seeds."


Sounds pretty consistent with what your saying bree

Well there you go! I think with my next seeds I am going to start them on 14/10 when they pop and after a few weeks go to 16/8 (or 18/6).....With the light on less the temps should be lower anyways....make them humid of course...see if I can get all females, eh? :jointsmile: Bree
