I am building my first stealth grow box. I got an armoire for free and made some mods to it today. Here's the cabinet as I got it. Then I cut the bottom out and put up a light curtain. Installed my vents. Took out the bottom of the top drawer so the pots will sit in the second drawer. Put in door locks and wrapped the inside. I have a grow journal too, but I thought this build might get more attention in this thread. I'll link to my grow when I figure out how. Two of those plants are going to flower in the box I'm building! I have a carbon filter, 180cfm exhaust fan and 400watt MH with 4 "200 watt" CFLs. Let me know what you think.
No, I used what I had. It's a photographic reflective umbrella that I cut up making the light curtain for inside the doors.
Looks awesome! Check out my diy chifforobe in my grow journal! BTW, mylar is incredibly cheap, all you need is construction adhesive and some scissors. Just saying http://forum.grasscity.com/index.php?/topic/1315929-Techead's-Indoor-Newbie-Grow-Journal
