Heh, that's why I went with a wood cabinet instead of a grow tent too. You're smart to put casters on your cabinet, btw. I wanted to do that, still have a pile of casters I bought, but the ceiling of my room slopes, and adding the caster would have meant moving the box forward several inches, which would have put it in the path of a door, blocking the door, so I couldn't.

Then we had a massive power outage, lost power for 3 days, and I wanted to move the cabinet nearer window lighting, but when I went to move it, it was impossible. Hell, the cabinet alone weighs almost 300 pounds, plus the stuff inside it, and I'm not exactly a huge guy. Lacking casters, I had to resort to Plan B to provide light for those three days: batteries and flashlights!
