ALL HID bulbs need ballasts,

there were some HPS bulbs coming out of china that had a uilt in ballast.... I heard they gave off a lot of heat...

ive never heard of a bulb exploding if it hasn't been wet or gotten moist somehow.
i was helping a friend in his room last week and he was misting the tops of his budding plants. I told him he was raising the humidity and opening himself up to mold attacks, but he said "aww, miracle grow in a mister wont hurt em". then he accidently sprayed the bulb and it popped. so i guess there are 2 reasons now i dont folar feed.

but a bulb shouldent explode under normal circumstances. how many streetlight bulbs do you see exploding??

Question woundering if I could use a 250w HPS for veggie and flowerin, since its the only lite I have rite now? I did pick up some floros 2day, so not sure if I should throw that in there as well.

I have like 9 seedings, in a closet that is like 20inch (W) 38' (L) about 7feet tall. Soil mix promix, some worm castings.. The seedings are maybe like 4-5days maybe more. Any tips on the HPS would be a great help, haven't done this in a long time.

Thanks
