could you explain or show a pic on how you mounted your ballast Im refering to the bare ballasts that you wired yourself
If you mean the HPS ballast, put it in your grow room, on a shelf above you waist, way clear of water and obstructions peace "V"
i fucken throw mine on the floor... dude its whatever. The parts inside dont care where they are, and most of them are designed for use outdoors (in appropriate housing of course) so they are pretty rugged. if it seems like it runs hot, then worry about it. otherwise, its just gotta be within cord reach of the hood.
