Alright 6 weeks have passed, boy time fly’s when your having fun. Now we need to sex our green jungle to eliminate the male plants. 12 hours of light is now required. 12 hours of lights on, and 12 hours of lights off. This is called the “flowering cycle”.
For medical use, the
female plant is the only plant you’re interested in growing to full maturity. You don’t know what the sexes of the plants are until they show you, and that’s weeks after you change your light cycle to the flowering cycle.
The Male Plant often show’s it’s sex first, a few days before female plants show their sex. What you want to look for is 2 white hair looking strands growing out of those little football shapes that are appearing where the branch leaves meet at the main stalk. This is a female plant showing its pistils. Pistils (hairs) are what collect pollen from the male plant and fertilization takes place. You do not want his to happen for sinsemilla buds (seedless marijuana). Seed production takes away THC potency from the buds.
If they have a short stalk under that little bump or hang down and have a five-sided sheath covering these bumps, it’s a male plant. Get it out of the room now. Make sure it is far away from your grow room, because even after you pull the male plant, it’s pollen sacks can continue to grow and release it’s pollen ruining your grow room.
All the lady’s (female plants) will be glad you did not want any unwanted kids or seeds in this case. When a female plant produces seed, it uses THC. So if you have seedless marijuana (sensimella) all the THC that would of gone into producing seeds, is now dripping and covering THC Crystals all over your plants. This is what you want.
