Here's the thing I don't quite understand about temperature: I read everywhere that 75 degrees or so is optimal. I also read that you can put your light real close and as long as your hand doesn't burn after a minute, your plants would be fine. So my hand can withstand temperatures way higher than 75 degrees! This seems like conflicting info--can anyone clarify?

Apologies if these seem like dumb questions. I have spent lots of time doing lots of research, but some stuff just doesn't seem to add up.
Sprite Reviewed by Sprite on . light question on newly transplanted clones Howdy pals. I have 6 AK-47 clones, newly rooted, that I just put into 1 gallon soil pots a few days ago.

My water and soil are ph 6.5, closet was at 85 degrees yesterday because of the outdoor heat and the light, but very well ventilated. I put them back to the Rating: 5
