I am by no means an expert yet, but thanks to the posts by you and some others, I'm getting there. I'll post a full write up on my set up in a few days, but I believe my RHP is keeping ambient temps at around 80 on the cool side, 2.5 feet away (lateral) from the RHP...a little warmer on the hot side. The top of the bark in the hot side temp guns at 90 and 80 on the cool side. Probes on the floor, under 1.5" of bark show 84 hot and 80 cool. This in a room in the mid 60s. These are just from a few looks at the temps. I really need to monitor things consistently, over weeks, under different conditions, to know what the heck is really going on. Oh, and I have 2 flouresents burning from 6am to 9 pm, which are probably helping. Ill find out how much by monitoring at night I'll also find out how temp swings in the room change things...dont think I'll get an 80 degree cool spot when the room is 82 in the summer. Sorry so long, but it's kind of interesting getting things dialed in. By reading your posts, you must think so too.
