Ok, tomorrow I'll cut up two 2" holes on the top-side of the cabinet and install both fart fans...

I'll then drill a couple of 1" holes on the bottom for the intake. I'll start with two 1" holes... then, depending on the suction of the front door panel, I'll drill one more... or two more... or three... ???

As to the temperature probe, I'm going to make that little cardboard tent... that was what I was talking about... Excellent. It's just, that I think I'm getting incorrect readings from that probe... I'm sure everything will clear up once the 'tent' is made and installed.

I'm going to upload some pics in a few minutes... but I was able to place the plants about 1" away from the reflector's lower glass plate. I did the 'hand burn' test... and to be honest, even placing my fingers in direct touch with the reflector's glass, they didn't burn. It was warm, but not uncomfortable. In fact, it was much cooler than my CFLs (when I used them). So now, I've got the girls about 1" from the glass... I'm sure they're liking it...

They've been like that for a couple of hours, and they're not showing any signs of burning or anything... I'll keep an eye out.

I'll update in a little while,
