Either you're stronger than you think, or your cabinet is smaller than mine, because when I built mine, I physically could not stand it upright myself, had to get a contractor guy working on the house to help me upright it. I think mine weighed 230 pounds. Hell, I had to pay the contractor guys to get it to the house and up the stairs too, just too freakin' heavy!

If you're going to ScroG, and are patient in veg, you probably don't even need four plants; one or two could be enough. Three was too many for me when I let them veg too long. I'm gonna try two plants, maybe even just one, next time.

Sorry about your fan! What brand/size? But three feminized plants all sprouted up, that's good news! Hope they all do turn out to be females for you!
