I have two plants coming up and starting to grow second set of leaves. I was wondering if my lighting is fine? I have a grow light that is just a big bulb from walmart that puts off alot of heat (used just for warmth)keeping it about 75-80 degrees. Im using one CFL per plant each is in a clamp lamp and 1200 lumens 19W is that good enough?Im a new grower and in a 2x4 space indoor in soil
