Howdy Y'all

I'm gonna be moving shortly and want to have a slightly bigger grow area to get some higher quntities of bud.

I'm gonna get a built in cupboard that will have about 5ft headroom and measures roughly 50inch wide by about 25 inch deep. I'm thinking of either a 250 or a 400W HPS in there.

I've been mostly growing stealth up to now and enjoy it, but I do want to grow a nice indica (or indoor sativa) without topping or training to see the plants's full unadulterated potential. This means that penetration is important, I would like the light to get quite far down the plant. I also like to keep things simple so don't really want to piss around with CFL sidelighting and such...

Would 400W be overkill in this space with a 250W doing an optimum job?

FILL ME WITH YOUR WISDOM!!!

hiya Blunt, what's up buddy?

let's see, you got 8.68 square feet there, so @ 50 watts per square foot, a 430w grow lamp will be spot on, otherwise a 400w will be fine.

The footprint of the room is not square so 2 250 lights would give you even light coverage in both length and width over your space and about 57 watts per square foot. With the depth being only 25" I think that's a bit narrow for a 400's footprint and the lenght of 50" will leave the edges with not much light.

sure, but the footprint of the light is oblong anyway, and you can always adjust your reflector accordingly.

Or you can buy the lights that will cover the 2' x 4' area perfectly. Does not make sense to use a single 400 in that area unless it's on a mover. My opinion.

^^I agree with GroNut, unless you have a mover you should go with dual 250's in that space for the best coverage.^^

What lights are you talking about GN? Fluoros? Or special kinda reflector?

I'm voting for the 2 - 250's.

Wow guys, thanks for the swift answer. Nice to hear from u Sat...

I'm gonna have the light adjustable so can raise and lower as I need to, this should also help with coverage.

Problem I got is that I can get a 400W at the same price the 250W (weird huh?), so buying 2 250Watters will be twice as expensive. It's gonne be either one or the other, and by reading the replies above the consensus seems to lean towards the 400W.

Edit that:..... The 2 250's seems to be preferred. I'd prefer them also but don't want to doll out twice as much loot...

i guess you guys are right about the dual 250's, my metric brain was thrown off by the inches, but after converting i realize that 50 inches is too deep for a 400w.
unless you have a light mover. i'm constructing one for myself as it happens, so blunt, when it's done feel free to copy my design, it's gonna be the shit.
