well i need a little advice on my light situation. after my 400W HPS mysteriously disappered off the moving van (hmmm 67 boxes made it,yet THAT one didn't,i wonder why ) i'm faced with the daunting task of finding a new one at a reasonable cost. well i have found one but i'm having an internal dilema about wattage. you see, my grow space has changed sizes from a 3x3x6 closet to a smaller (but longer)box roughly 5.5Lx2Wx4H. so i am concerned that the 400W will be too much heat (even supurbly vented as it is) for this new space. on to my internal conflict: there is a 250W HPS for about the same price, obviously is less lumens but also less heat in that small space. i've never used anything below a 400W (never needed to) except for fluros (which is neither here nor there in this matter). my concern is this; this box isn't going to be my permanant space, i will be eventually using a taller,deeper cab so i will want my 400W (maybe more) when i do switch. that being said, i most likely won't be doing that until at least x-mas time maybe even next spring. so do i get the 250W and just buy a second when the change comes,or do i buy the 400w now and pray it doesn't fry my plants? advice, ideas, i'm open to suggestions on this one,since i'm at a loss on which one to get. my current grow is an abused plant rescue so i really don't want to bake them with uber-heat now that they are recovering so nicely. many thanks in advance, MamaG ETA: Mods, sorry i meant to put this in the grow room set-up forum but suffered a brain-fart along the way. move if needed.
