I keep my growroom temps roughly in the mid-70's (by estimation), try to be conservative with nutrients, and am careful not to overwater...and many times I still come out with about a 60/40 percent of females-to-males. Sometimes I seem to have a stroke of luck, and it's more of a 90/10 ratio. Sometimes it's a 50/50, or less. I'm sure there are ways that you can theoretically influence the numbers of females produced, but I'm not sure how much of that has been validated...and how much of it is just hot air.
