Well. I finally did it. I got off my ass and finished my mini ClosetMaid cabinet today. 23,400 lumens in 2.13 s.f.
I've had this cab and the 150w HPS for over 2 years without producing a gram of jam.
The cab inside measures 22" wide, 14" deep and 32" high.
I drilled two 4" holes in the floor of the cab for fresh air intake. The false bottom beneath the cabinet allows air to enter from the rear.
I covered the intake holes with carbon filter cloth and a fiber filter to keep out nasties and dust. A wire shelf from an old fridge acts as the floor and sits about an inch over the cabinet floor allowing air to enter from below the bubbler tub.
I installed a 4" toilet flange in the upper rear corner for air exhaust. A 120mm PC fan is mounted on the rear of the cab using screws through the fan flange flange and cabinet wall.
The fan is controlled using a 12v 1A transformer and is speed regulated using a Zalman Fanmate. A second unregulated 12v line runs inside the cab to run another PC fan for light cooling.
On the back there's a power strip, 150w HPS ballast, PC fan controller, air pump, timer, transformer and a fuck-load of wires.
My DIY carbon scrubber attached directly to the flange inside the cab. The scrubber is made from 4" and 5" duct, hardware cloth, worm clamps and pantyhose. I used pet store activated carbon making sure to vibrate it in tight using a rubber mallet lightly beating the outer wall of the scrubber.
I've found a 1/2" bed of activated carbon works best with PC fans, since they have trouble with higher static pressures. 2" carbon beds makes for shitty flow and higher heat.
Inside, I installed a 150w HPS bulb (15,000 lumens) in a DIY bake-a-round cool tube and mounted it to the ceiling. On the left wall I installed an adjustable CFL light fixture which moves up and down in a pegboard slider.
In the fixture went two 85w CFLs (4,200 lumens each). On the fixture, the second PC fan is mounted to cool the lights and blow across the plants. I put a 20w CFL in one holder just for size comparison purposes.
Initial testing over the last 2 days looks like the cab runs about 2-4 degrees over ambient with just the HPS and 4-6 degrees over ambient with both the HPS and CFLs bursting brightness.
The cab is almost silent and only has 2 pinhole light leaks which you really have to search for. Installing the EPDM gasketing on the door and mitering the corners makes all the difference in preventing light leaks.
I installed the cab between my furnace and water heater so there's usually sound in the room which deadens the fan and air pump sound.
I'm still need to build my SWC tote with screen as I'm not happy with my current tote size of 16L.
Just for giggles, I popped my twin 6 week old Citral girls in for a photo op.
Yummy.
Once I get my SWC tote and scrog screen set up, I plan on popping in a couple of the Citral clones I took.
Let me know what you think.
