it was a remote ballast so it was behind the box. i lined the bottom with plastic and set the pots on top of some plastic eggrate(the stuff they use for lights in drop ceilings) so when i flushed i would just use a shop vac to vacuum out the water. in a small cab remote ballasts are a must imo. you don't want the extra heat from the ballast inside the grow chamber. i rewired this light from home depot to make it remote. it's really simple.

i did replace the bulb with a horticultural bulb (better spectrum and a few more lumens)

notorious, you train them through the screen long before buds form so the holes are plenty big enough to fit the stems through.
