The medium is whatever you are growing in. Dirt, rockwool, rocks, water...etc.

To find out if its male or female you will have to flower the plant. To flower the plant you need to put it in 12 hrs of light and 12 hrs of complete darkness. After a week to ten days you will start seeing the flower. Males will have little pollen balls that look like a bunch of grapes. The female will have a little tear drop bud with two white hairs coming out of it.

You want to kill the males. They do not produce bud. Only pollen. You dont want the pollen to get on the female flowers or it will produce seeds. You pretty much have a 50/50 chance of having a male/ female.

You are prolly doing the smart thing and practicing on some regs. It would suck to spend money on some fire seeds just to kill them. Good luck on the grow and let us know if you have anymore questions.
