Hard to tell - looking female, but you should know any time now, it'll spit two hairs out

heres what I meant with the box inside the cab - it'd be super easy with 4 36 inch 2x4s, 2 hinges, and two pieces of plywood (one of them 36x23 ish) - less than 10$ I bet, plus a couple of bucks for a latch and weatherstripping to seal it, couple of black elbows, etc etc. That veg space would be 3 ft tall, 23 inches deep, and whatever the distance is to that right wall - roughly 2 feet? And would leave plenty of room to bloom in to the right. You could veg 4-6 plants in there pretty easily, although you are right, the 4-footer would not fit. You'd need to get some cfls and fixtures.

That dresser would work too - check its size though, it might be easier to build the enclosure

Anyways, happy to help ya out whenever I can - Hope shes a femme for ya and I'll keep checking in!
