Since your on a small scale, the male wouldnt do you any good so your option is to pull it. When you find a male you should pull it immediately, just take the whole plant, pot, medium out of the flower room and cut it up, throw it away. You want to keep an eye out for the "balls" to show, as soon as they show, you want to remove that plant. The "balls" could explode at any point and get your girls preg.

Hope that helps.
