As explained in the paragraph above, you can’t turn a male plant into a female. But, there are methods to make a make plant show different female characteristics. Take note that using chemicals for these methods can be harmful to both pets and people. First, grow a marijuana plant until it shows the male-like pollen sacs. You will need a bottle of ethylene, which is a female marijuana plant hormone. Then, prepare a pair of gloves and face mask as personal protective equipment. You have to sprinkle some ethylene overtop of the plant’s branches. Put more drops on the leaves and stem joints. Set a lighting system to 12 hours of light per day, and wait for the results. Increased levels of female hormones in male cannabis plants are a factor in triggering female flowering development. It is more effective if you apply ethylene when the mature flowers are still not formed. Take note that you have to distinguish if the plant is a true male to make it more effective.
