Lol I'm a plumber , all U need to know is shit runs downhill ,don't bite Ur nails an paydays Friday lol, but have ran my fair share of wires, anymore I do everything, just been noticing the plants under the 630 were getting heat stress at the end of flower an I've been reading up on stuff an they say U really should have an air cooled hood for a 630 but the glass blocks some of the goodness so ... An don't wanna buy 2 315s if I can convert the 630, like I said I figured it would work as I've seen other ballasts like that just wanted 2 get a 2nd opinion, an yea haven't burned anything up yet lol , ::KNOCKS ON WOOD:: lol
