is it ok to put a seedling around my female?

I have a female silver haze plant 2 weeks into flowering, but the other day a friend of mine planted a purple kush seed and it started growing and he didn't know what to do with it so he gave it to me. the sex is undetermined right now and I am wondering if this would be a problem with my female if it happened to become male. can I leave them in the same room for now or is this something I should not do?? I take the seedling out of the grow room when my female goes to dark for 12 hrs and is put on a desk with a 100watt CFL over it for another 6 hrs them it goes in the same room as the female.

Your plant will be fine.......if the seedling turns male and pollen sacs become visible....at that point you would have to remove it......unless you want seeds....
