The boxes are nice but only as temperature controlled as the room they are put in. There is no heat or AC. Just fans. They are solid but small. Not discrete but cool looking. I have a super closet type cabinet I built when I started growing a long time ago. I had to modify it a lot to get it to work properly. Added vents, to help cool it. A chiller to cool the res. A blurple led when those came out (lol long time ago). Finally got it to work and I learned a ton by doing so. It wasnt any of the things I hoped it would be but I got it to work and I was growing my own bud! Now I use it for seedlings and veg. I grow organic so no hydro. I also dry my bud in it. Tents are much much better but at the time I was aiming v to be secretive and I thought a cabinet would blend into my garage better than a grow tent. legal now so I'm not really hiding anymore. I built a dedicated room.
