Bricktop, I wanted to thank you for this post, the one that contains this part:
The environmental factors that influence the sex of the cannabis plant (or the flower in the case of hermaphrodites), are among other things:
The quantity of nitrogen and potassium of the seedbed. Humidity and moistness of the seedbed.
Level of temperatures.
Colour of the light used.
Length of daylight.
Stress, any form of stress, makes that more male individuals will originate from seed. Even the taking of cuttings from female cannabis plants may produce male or hermaphrodite cuttings.
To optimize the result, changes in one or more of the above-mentioned environmental factors for a certain period during marijuana growth, may be applied. During this time these environmental factors will deviate from the standard growing system for maximum harvest and quality, as described in nursery literature. The desired change(s) in the environmental factor(s) are started from the moment that the marijuana seedling has three pairs of real leaves (not counting the seed-lobes). This is the moment that male and/or female predisposition in florescence is being formed. After approximately two weeks the standard growing system can be reconverted to.
Of the 5 above-mentioned environmental factors the first three are the most practical:
PERFECT!!! I knew thats what it was, just couldn't remember where I read it before. What did you get that from, ie a book, etc.? Interested in doing some reading (read the original marijuana growers guide when I was 14 cover to cover) never get enough info. And thats another thing I find amazing, how I can still remember shit (maybe not fine details, but still a lot of shit) considering I was stoned 24/7 from the time I was 13. So much for memory loss! Even short term isn't bad, still. I just have a hard time remembering WHERE I put shit, not WHEN I put it there! Doh!

Of the 5 above-mentioned environmental factors the first three are the most practical:
- Level of nitrogen and potassium of the seedbed: A heightening of the standard level of nitrogen makes for more female cannabis plants originating from the weed seeds. A lowering of the nitrogen level shows more male cannabis plants. A heightening of the level of potassium tends to show more male marijuana plants, while a lowering of the potassium level shows more female marijuana plants. A combination of a higher nitrogen level for the period of a week or two and a lowering of the potassium level is recommended.
- Humidity and moistness of the seedbed: a higher humidity makes for an increase in the number of female cannabis plants from weed seed, a lowering for an increase in male cannabis plants. The same is valid for the moistness of the seedbed.
- Level of temperatures: lower temperatures make for a larger number of female marijuana plants, higher temperatures for more male marijuana plants.
- Color of light: more blue light makes for female cannabis plants from seed, more red light makes for more male cannabis plants.
- Hours of daylight: few hours of daylight (e.g. 14 hours) makes for more female individuals, a long day (e.g. 18 hours) makes for more male cannabis plants.

(plus be good for comparison on pheno variation in the strain, germ rate, etc.)
