the cabinet started out as a 6 foot tall, 4 foot wide wardrobe with 2 doors. i cut off the top 2 feet of the cabinet and lowered the top of it. i then framed the inside of it with 2x4's for the needed support of the tank. then i created the air scrubber chamber on the left. it was the depth of the cabinet, 20" x 12"w x 36" tall. on the wall splitting the air scrubbing chamber i used 2 4" DC powered fans. they sucked air up through a hole in the floor between the two plant totes. if i remember correctly the fans were rated for 100-150 cfm. on the floor of the air scrubbing chamber i cut a 10"x16" hole, placed an air conditioner return air filter over it. built up cardboard sides on the edges of the filter and poured an 1" thick layer of activated carbon over it. there was also a small ozone generator hanging inside the air scrubbing chamber.
both the intakes and exhaust were open on the back side. i had framed channels underneath (for exhaust and intakes) to prevent light leaks.
as i stated, i started off with so much shit crammed in there. i found in the end, things rain cooler and better with just 2 bare 150 bulbs. 200 watts of LEDS will do you right. you can see in the pictures i scrogged, so i built some 1/2" pvc frames and chicken wire to support the plants.
getting the light leaks on the front doors was the trickiest, but some marine weatherstripping did the trick.
i too wanted to have a bare, natural looking cabinet, but that plan i had in my head did not work out. since i did have a key lock exposed on my doors, i had the ex wife sew up fitted cloth that just laid over the whole cabinet.
the plant totes were small 10 gallon sterlite brand, i believe. actual grow chamber 20"D x 36"W x 48"H.
i had to scrog everynight if i didn't want a mess. if i skipped two night, it would take an hour to scrog all the stretch back down.
btw, i started with 2 plants per tote. that was also too much and unnecessary...
couple more pics.
hope that helps, if you have other questions, fire away...
