I was recently reading Marijuana Horticulture, the indoor/outdoor medical growers bible by Jorge Cervantes.
It states that there are several environmental factors can influence the sex of the seedling once the seedling has three sets of true leaves.
Those factors are:
Increased nitrogen makes more female plants. A higher nitrogen and lower potassium level for the fist two weeks increases females.
Lower temperatures increases the number of females.
High humidity increases females.
More blue light increases females.
Fewer hours of daylight (14 hrs) increases females.
I am wondering if anyone has any experience or thoughts on this. Also, wouldnt adding nitrogen to a seedling be dangerous to the health of the plant?
