My homemade cabs

Hello fellow growers, so here i got two homemade grow cabs that are made from cut 2x4s, staples and panda polyfilm. First we have the white one, its 2x2x6. (sorry for the crappy pics) i use a 5000 btu ac to cool both cabs, for the white cab i run a piece of duct from the ac to the inside of the cab. It keeps both the cab and my 250w hps cool that i can keep it 4-5 inches from the top of my plant. inside the cab i have 3 23w cfls and a small fan and at the top i cut out a 6 inch hole to vent hot air and that pretty much it for the white one. The black one is alittle smaller at 2x2x4, its pretty much the same as the white one (again sorry for the crap pics) since i have this cab in my closet im only using cfls for now, ill be using 4, 23w maybe acouple more. im only using cfls because they dont get hot and the ac that i have keeps this cab at perfect temps after i harvest the plant i have in the white cab im probably gonna rip off the polyfilm and redo it. Let me know what u guys think of my cabs. Just keep in mind that ive only been in the growing game for 5 months now so be easy on me Thanks for stopping by and happy growing!
