"Enviromental factors star influencing se the moment the seedling has 3 pairs of true leaves. Factor include but are not limited to:

-N and K levels. Increasing N makes more females. Lower N makes more males.Increase K increases the tendency for males;Lowering K level encourges female plants. A higher N level and lower K level in the first two weeks increases females.

-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
Chronic Chrissy Reviewed by Chronic Chrissy on . Look Look! two plants on 12/12 from birth here are two plants that have been under 12/12 since seed. Under 15w of light (yah you read that right) they have both popped pistals even though thier nodes are not alternating (unless they are just starting). The taller one was dropped and snapped in half, and yet recoverd. So there was some stress. They do not have a fan on them...lol...they would never be able to hold weight...but I'm thinking that enviroment in the beginning plays a HUGE factor on gender! They were born on Rating: 5
