Hello Mr. Chiln -

Can you exhaust your closet? Will heat be an issue?

If you can exhaust your closet and draw the heat out of the room/closet, you should most definitley go with the 400.

cheers

my closet is simlar to that size and i ran a 400 will little problems. in fact im upgrading to a 600 in a few months

One Plant? use 250W. No need to go that big for one plant. You'll have a shitload of lumens with one 250WHPS

nice... any heat issues?

While I agree that a 250 would grow one plant just fine, there are some other things to consider. For example, a 430 HPS will grow larger, fatter buds. And then, there is the possibility of expanding the grow as many of us have done. You know how it is ... you start out with a 50cc dirt bike and by the time you've progressed to a 500cc monster, you've spent a load of money moving up the ladder. So ... with that in mind, I'd suggest the largest light you can use without having a heat issue.

there was a small heat problem (about 84 degrees) but i upgraded my inductor from a 250cfm to a 500 cfm fan and place a Y splitter with one hose exhaust the hood itself. i love the hydrofarm hood

The bigger the wattage of your bulb the bigger the yield of your crop.

I think you should clarify that a bit mogie


Shouldnt you mean to say that the more lumens the more yield

I only say this because CFLs are low wattage but high lumens

Lumens being the main factor in lighting

Teknique the original post was asking about either a 250 or 400 watt bulb. My answer was in response to that. So no I don't need to clarify.
