EARLY SEXING
It's possible to tell the sex of a plant early, and thus move male plants out of the main growing
area sooner by covering a plant's lower branch for 12 hours a day while it's in a constant light
vegetative state. Use a black paper bag or equivalent to allow for air flow while keeping out
light. Be sure to set up a regular cycle for these covered branches. If light is allowed to reach
them during the dark period, they may not indicate early at all.
Use a magnifying glass to look at the early flowers sex type. A male plant will have a small
club (playing card) looking preflower with a small stem under it. A female flower is usually a
single or double pistil, white and wispy, emerging from an immature calyx.
