This is something I just built when I was bored. It only cost me $60.00

Material List

9 Pieces - 2"x4"x8' KD
36 Pieces - 2.5" Wood Screws
1 Roll of Black Poly
1 Rol of White Poly
6 Rolls 450" Double Sided Tape
1 Old Shower Rod for holding up Light.



------------------------------------------------------------------
Assembly Directions

Cut four pieces of 2"x4" to 78".
Cut ten pieces of 2"x4" to 48"

Simply assemble four 4' pieces together to form a 4' square. Do this twice. Make both sections identical.

Assemble upright 78" pieces and tie together both square sections.

Use the remaining two 4' pieces as cross members for support and for holding the light up.

When assembled it should look like this.



Next thing is to tape up the edges of all three sides, as well as the top "roof" with double sided tape. This stuff works like a charm. Rub your finger over the poly and tape until you get a good bond. The black poly is applied to the outside of the wood frame while the white poly is taped tp the inside framing.
I don't have updated pics with the white poly installed but it serves as a great reflector.



You can get this stuff nice and tight. See how the roof looks so rigid. All I did was stretch the poly and stick it good!



The poly is ALMOST a complete light blocker. I used a sheet to seperate it from the veggin/clonin chamber next door. This takes care of any escaping light. I also have a temporary sheet that goes over the front but I only use that when I know I will be home when the light goes on.



It's important to lay poly down on the ground. I found this makes for super easy clean ups. I've got more than enough room for another light if I wanted and could grow a 5.5' monster in there! The other big advantage is I can rip it apart in about five minutes. Well hope this can help anyone out there on a budget. I've got the CUP coming up so $$$ was a huge issue! Enjoy. Later OH

Nice Job OHenry. I have a few questions.. How do you take care of ventilation with this setup? Do you vent the flower chamber separately or are you venting the whole room? What about carbon scrubber?

I have a Vicks Air Purifier and a small fan. I have central air in my house so I can keep it on the cooler side. I built it right under my air duct so in the Summer months I will pipe right in the cold air. Should be a HUGE plus! For the smell I have some small battery operated scent controllers and stink killers. They work great. I replace them monthly for about $5 a piece. Well worth it. Smells like SPRING FRESH in my house. Later OH

Very Nice. great example of not spending too much yet gaining everything.

OHenry,
Lookin' good. I did the same with some 1/2" angle iron and my welder. I covered mine with cardboard and than used mylar inside. I used wall paper to cover the cardboard outside, to look like wood. People think they are cabinets. I made one for veg and one for bloom. Veg is 3'x4'x4' and bloom is 2'x3'x6'

Im done with my box all but the exhuast fan blower?
What size is needed to cool a 400 w MH.. also use a 400 hps bulb for flowering.. woulda 265 be a good size? peace..

sack

sack. I use a 65 cfm 4" fan. it is not noisy and it mounts to my greanleaves reflector. I also have a glass screen. My plants can get up to 12" from the light. I use a 400 hps for flower.

Fredster. These are so easy to make, and I use the sterilite tubs; 19 gal for my aero dwc buckets. It all fits nicely together in a corner. The veg cabinet runs on less than 15apms of current with fans, lights, and aeroponics systems and timers. My biggest cost is the lights, mylar, and the fans. The angle iron is cheap and cardboard is free!

The 400 w hps bloom cabinet also uses less than 15amp circuit draw. The bloom cabinet holds NINE ladies. I run WW, BB, SSkunk, Special Skunk, OrangeBud, and others. I let 'em grow wild and make them SCROG-like in their growth patterns through trimming and pruning during yhe veg stage.

Sometimes I spend hours pruning for bloom development. I am developing a double cola growth for the OB now. looks promising.

Good Luck!
