Hey Firsttimefarmer

It's not the soil alkalinity that determines gender it's the genetics. In all the experiments I have done there is only one way to create female plants. Get a large tray of rotting fruit put a fan behind it and let it blow at the plants as they grow,(from seed). Add more fruit as the pile shrinks to a rotting mass of fur. I really don't know what chemical processes are at work here but I know it works. The first time I did it I got eighteen out of eighteen female plants which anyone will tell you should be impossible. With subsequent cuttings I ended up with seventy-four ounces, some buds as long as two and a half feet.

My advice is use clones and don't worry about gender.
