After doing a bit of research across the web I decided to give this a go. So far the box is working like a dream so I figured this would be a good place to share it. My box build inventory list based on using the DWC method. MARS HYDRO Reflector 240W Full Spectrum Grow lights for Indoor Plants Veg and Flower Axial fan 120 x 120 x 38 mm | Airflow: 110 CFM | Noise: 47 dBA | (inlet fan drawing fresh air) Reflectix BP48010 Bubble Pack Insulation (lines all area inside the box minus roof) Multifunctional Infinite Cycle Programmable Plug-in Digital Timer Switch With 2-prong Outlet 195 CFM 4" Inch Inline Ventilation Duct Fan (exhaust fan) 4" dryer vent wall adapter 4' of 4" dryer vent hose 8 Inch Air Carbon Filter Odor Control with Australia Virgin Charcoal (exhaust air filter) RX Grow Nutrients RX Bloom Nutrients RX Bulk Starter Plugs Net Pots Air Pump Air Line 2 Eight inch bar style Air Stones plastic container 13"x16"x6" (holds 2 gallons of water and keeps water level 1/4" below net pots) 40 GPH Submersible Water Pump w/ hose (for draining water) Ozium Odor Eliminator (just in case) 1/8 Inch 8-Feet Long Heavy Duty Adjustable Rope Clip Hanger, 150lb Capacity (over kill I know) Box dimensions: 2'x2'x4'2" Build materials 2'x4'x0.25" - 5 ea 1'x1'x8' - 2 ea 25' roll of 0.25" vinyl self adhesive weather stripping insolation 1 tube of calking 1 2lb box 0.50" drywall screws (they have a thinner shank then other screws and cause less splitting in the thin wood) locking clasp 2 each cabinet door hinge 18 inch 2 each small hanging hooks 4 each (you'll need these to suspend your light) Tools used Cordless drill Cordless Skill Saw Measuring tape Level knife calking gun 4" hole bit (if you don't have one already get ready to drop about $40 on one) 1" hole bit (if you don't have one already get ready to drop about $12 on one) #2 drill bit cross tip Staple gun Putting it together: The two 1x1x8 ft sticks get cut in half. Now you have four 4 ft sections. I then cut 10 inches off of each of them to reduce them to 38 inches each. I use the remaining 10 inch cuts as the cabinet legs. I cut 1 of the 2x4x0.25 sheets in half now that makes the floor and roof section. fast forward ahead (after I put it all together) I lined the door section with the weather stripping and then used the calking to seal all the inner area where it was wood to wood contact. I put my 4 hooks 1" inward from each of the corners of the frame posts inside the box. I drilled the 4" inlet and exhaust ports one on the outter left side of the box (based on location you can put it anywhere you want) and the 4" exhaust hole in the back floor corner. I then installed the dryer pass through wall adapter in the floor hole. I recommend using some of the calking to help create the seal before screwing it down. So after it's all together and the holes are cut, using a staple gun I covered ever surface with the reflective bubble insulation except the roof since the light will be suspended there no need to reflect back down. Here's what it looks like complete and ready to go. And the best part.... My storage area. This is also where I put the exhaust fan and carbon filter. It leaves enough room to store everything this stealth micro cabinet needs to operate. This is the first time I've tried writing something like this out so if you have questions please ask away. If you have suggestions I'm all ears. If you just wanna say well done that's cool too. If you duplicate it comment with a photo of yours would be cool to see how you put your own twist on it or if my post helped guide you through putting one together. BTW this fits in most closets. I'd recommend putting it in the back of a walk in closet. It's so quiet too, not even as loud as a bathroom exhaust fan when on IMO.
