Absolutely LOVE the presentation of your cab design Anti. I also dig the dual chamber setup you have going there. Opens up a lot of options I don't currently have right now.
I was wondering if you had considered using the PL-L lamps with that design yet?
Are you suggesting that I mount them vertically on the walls? Given the setup you see, what would you do with the $100?They really are the most efficient CFLs for growing right now and, since your cab size is perfect and the wattage is just about the same, only a bit higher, I can't see why it wouldn't be a super win situation for you.
Granted it would run you about $100 for lighting on each side but you'd enjoy lower temps and a higher lumen output as well as an almost 2 year lifespan on your bulbs.
24" is perfect to mount a PL-L lamp in.
By my math, 19,000 lumens would be a bit over 9000+ lumens per square foot.Then again, that's 19,000+ lumens in that little of a space. Might be overkill??
....Basically, I would just need to build a little shelf bracket about an inch below the lights and drop a pre-cut piece of glass in. Is there a certain kind of glass I'm looking for, or just regular hardware store replacement window glass?
I'm going to buy all of the lumber needed to build this thing tonight.You've put a lot of thought into this and I hope to see a successful build soon.
the room's 17x17 so it's 2.0164 sq ft ... (8) 27w CFLs
At 50 watts per square foot, your CFLs leave you slightly underpowered but, not by much. Lumens measures the human eyes ability to see green light. Between spectrum, wattage and lumens, lumens comes in last if at all.
Each room is 2.01 sq ft.
Yeah, I've read through your thread and I spent a lot of my initial research planning how to build something with the PL-L in mind. But when I got to reading the Dr. Bud thread, the biggest thing that impressed me was:
He buys everything for his grows at walmart or lowes or whathaveyou. Nothing bought online, no credit card trail, no raised eyebrows.
I'm so paranoid, I plan to purchase lights and soil at different locations. All cash. At the self-checkout lane. Wearing a disguise.

I'd really like to run a cab that is as close to the dr. bud cab as possible, because I'm hoping to achieve similar results. Once I've experimented with the screw-in CFLs, I may modify or rebuild a new cab.
By my math, 19,000 lumens would be a bit over 9000+ lumens per square foot.
the room's 17x17 so it's 2.0164 sq ft... so 9422.73 lumens per square foot.
for comparison, in this room:
(8) 27w CFLs x 1600 lumen each = 12,800 lumens / 2.0164 = 6347.94 lumens per square foot.
Agent-Smith said:you could get get rid of that 4 inches or so of dead space at the top of your cab and move the exhaust to the side of the chamber.
I'm exhausting the way I am because the exhaust points need to be "invisible". If it exhausts out the side of the box, people may ask "why are there vents on the sides of your CD cabinet?"
The exhausts are going to be vented out the top of the box into little rooms that will be sound-dampened to help muffle the fan noise. I think it will make more sense when you see the step by step pics.
The only difference is that you've shrunk the height of the mother room and directed the filter exhaust to run out the side of the box.
