You can't trick "Mother Nature", as the margarine ad said.

Well, I think you have to grow a plant that is mature enough to put out preflowers. A lot of people veg as long as they plan and then put their plants into the flowering stage. Then they start looking for preflowers. My two plants showed preflowers at 30 days from taproot appearance, over a month before I decided to flower them because they were finally growing alternate branches.

There is no surefire way to predict sex quicker than waiting for preflowers. My two plants were identical looking in every way, same height, same amount of stretch between nodes, same amount of secondary growth. Yet one was a male and the other was a female. So you can't even use the old adage that the male grows taller and with less secondary growth than the female before they start to show preflowers.
