I put the wrap on to keep up the humidity, as the house is really dry. I did just pull it off. I put the grow light higher so the light reached the length of the container, but I'm going to lower it & move it to the opposite side. I'll have to move it back and forth by lowering it. It's 68 in my room & the house. I have a indoor temperature gauge. Thanks everyone for the advice, this is the 1st I've used a grow light and grown from seeds, so it's all new to me.
