Some updated pics and the addition of a little suprise.

Plants seem to have recovered from the burning, one seems unsure though.
Soil is very dry in these pics, the fan and CFLs rape the soil of moisture very quickly. After the photo shoot I added an inch of MG moisture control soil to the top and watered heavily. I figure the minute addition of nutes shouldn't hurt much, it was an inch or less addition to the cups, so very minimal.
The last pic was a freebie I picked up a few weeks ago. I wasn't sure it was operable and I thought the bulb was burnt out... I was blindedly wrong. :stoned: In fact I'm still blind... It's a 150 watt HPS bulb with matching fixture. Since I know it works I will try to fab up a sheetmetal enclose so I don't have to install this heavy duty outside security enclosure in my cabinet.
Also not shown in the addition of a 1.5" passive intake mounting on the front portion of the floor and leading to the side of the box where the exhaust is. The pipe runs about 3' into the box and I configured a temp light trap with 3 90 degree elbow outside the cab, just to keep it dark while the silicone seals set up and then I can configure it how I want it.
I might try the HPS for the evening to see how the cab handles the temp and see if I need to work on more intake or exhaust.
