It's feminized white widow. I know growers frown upon using tinfoil, but it isn't really causing any perceivable issues for me. I'll remove it if I start seeing anything brown on the plant. Or will it be too late then?

I'm adding a fan once it gets a lil bigger, and I'll move the setup into a real closet.

It's on 18/6 right now, but I'm changing it to 12/12 tomorrow.
