As i said the cab is made out of sheetrock for fire resistance. Its built into a standard 2 foot by 4 foot closet.You can see on the right hand side how the front board of the cab is taped to the back of the closet which makes an air tight and light tight joint.

The door is plywood with battens on it to keep it from warping. The black plastic on top folds down to minimize light leaks around the door. When the door on the closet is closed its fairly dark in the closet but it's not closed all the way cause i have to allow air in.

The utility box sits on top and contains the hydrofarm 180 cfm blower and the ballast (150 watt e-conolight hps). Blower runs at 50% of full voltage. Voltage is reduced by an auto-transformer. The air is routed so that it moves over the ballast as it is exhausted by the blower to keep it cool.

The cardboard box at the bottom serves as a light trap for the cab air intake. Dimensions are about 2 by 2 by 4 foot tall. I painted the sheetrock because the surface paper has a tendency to break down over time if its not painted

Interior. As you can see it will hold 2 five gallon drywall buckets. The book and plastic box next to the bucket are used to raise the plants close to the light. It's easier to move the plant up than the air cooled hood down so i just stack books to get the plants about an inch away from the glass on the hood.

Hood. This is just a side view. Its a bit of a pain to take the hood down for cleaning. Next time i do Ill take photos of the inside. But you can see its aluminum sheet metal attached to a furring strip frame. Inside is painted flat white. The aluminum sucks up some of the heat.

The wire on the right side is the electrical connection which is very heavy gauge wire and can be easily unplugged for removal of the hood at cleaning time.

This is the air exhaust connection at the back of the box that sucks the hot air out of the hood. It goes through the top of the cab and into the utility box that sits on top.

a seed starts growin' and growin' and growin'

damn thats sweet twilson!

fuck i love utility and custom!!!

Well it's certainly nothing fancy or very high tech. What it is is cheap. I built everything except the blower and light and its made from pretty cheap stuff you can get anywhere. The air cooled hood cost me maybe 25 dollars to build.

The only slightly innovative idea was building it out of sheetrock which makes it somewhat fire resistant. Thats actually more important for guys with lights bigger than my 150 watt hps which i doubt could start fire. But you also have to think about the electrical part of the cab when it comes to fire. None of the electrical parts come in contact with wood. Any wires that are in contact with any surface are in contact with sheetrock ( i forgot to mention that i lined the utility box with sheetrock too even thought the box is made out of plywood ).

5/8ths of course?


we talked about sheetrock as a prefered material a long time ago back on overgrow.
cheap and forgiving and less tools needed and nearly fireproof...

good stuff

No just regular half inch. It basically has the same core makeup as 5/8 but thinner and the core is what gives it its fire resistance. Turns out that when sheetrock is exposed to high temps it gives off water vapor which is locked in the core under normal temps. I guess thats part of the way it reduces fire danger.

id always heard that the fiberglass made a big different holdig it up as it got really hot giving you the much longer burn throught rating

its required by code between garage and home here in california, from foundation to the roof sheathing.
