I got both the Intakes in. I drill a pilot hole, then use the 4" hole saw bit to mark the hole. Then I drill a bigger hole near the edge. A jig saw to cut the hole, then a trick I learned. I tap the edge bending it inwards slightly. Tap with little hammer then use the flat board. The inside was harder. Tin snips helped. I used a flat screwdriver and the hammer to get the upper one in nice and clean. I'll find 3" PVC with male ends to finish it cleanly. Two more holes to go. 2 in 3 out.
So I have to get the t-5's soon. I'll put their ballasts under it. Thinking dual 18" for each side.
OK guys, I may have a better plan. The 150W HPS, I used in the other fridge, so I know how warm it gets under it's Cool Tube. I know it needs it, and side lighting with it was a pipe dream. It needs a good 6" from the plant. So Cool Tube for HPS, locked in.
So CMH? If I use a Cool Tube like the other one I sacrifice UV-B. Didn't know that till a couple days ago. So new Mission for my DIY Portfolio. I can make a Hood for the 250W CMH with an exhaust like I use for the Cool Tubes. Unless anyone knows of a glass that doesn't block UV-B. I can change it into a Cool Tube if Temps make me.
So now on to the Heat Lamp. It's
http://www.petsmart.com/product/index.jsp?productId=3876122 100W. I'm not sure if it's the best one, but I think it'll throw IR and red spectrum. So my plan for it is a round hood with a 4" tin exhaust tube to it's fan in the center. Even if the bulb is only coming on for 15 to 30 min. the fan will be pulling plenty from there.
What do you guys think?
