150w hps question

How hot is a 150w HPS? I have a ply wood grow box painted white, 36x18x22".. With adequate ventilation, is a 150w hps a a bad idea? I dont want to burn my place down.

(It's only for 12/12, CFLs for veg! )

I think the only time you REALLY need to worry about it would be with a 600 or 1000w. If you have decent ventilation you should be fine. If you're still unsure, start the grow on a weekend or something where you have a day or 2 to watch it. Hope that helps.

I've done the same dimension with a 150 turned out well with out ventilation, but listen to yeah

Thanks guys, my nothern lights pure indica should be here monday by my reckoning and the light not long after..

this time it's an operation with a plan not 4 cfls and some bagseed muahahaha
