Two plants in a 3x3 ft. closet (sufficient height). White walls inside the closet for good light reflection. I'd really like to not have to vent and/or duct anything if I don't have to because I'm in a brand-new rent-house and don't really want to mess with routing hose anywhere. I am, however, willing to run a fan or two, for sure. Odor is of no concern at the moment. So, taking heat into consideration, is a 250-watt HPS going to grow a good amount of bud on two plants, or is the difference REALLY worth the extra money and potential heat issues associated with the 400-watter?
250 Watt HPS: Enough?

I am running a 400w HPS in a sealed up closet thats about 3x3 and wouldn't use anything less.

I got a 400w HPS in a very small closet too. I just put a fan in there and leave it running the whole time the light is on + 15 mins after it turns off. No ducts or nothing like that, I just leave the door open a few inches. Temps are 80-85F with the light on.

a 250w HPS is fine for 2 plants. I grew 2 monstrous plants in a 2x4 closet and yielded ~ 3 ounces from the 2 plants.
Then I grew 6 plants in there and yielded about the same maybe a hair more, but it only took me 8 weeks total. 3 days of veg (from rooted clone) and 53 days for flower.
Great quality bud. Check out my journals.

Is that 3oz per plant....or 3oz. for every 2 plants harvested, laserbrn?

That was 2 plants harvested for a total of 3 oz. One plant was a good producer, don't know the strain as it was a cali club clone and they are always full of shit and the other was blueberry and wasn't as big a producer. it did give quality though. I am sure that if I had two plants of the big producer I would have topped a QP pretty easy.
This last batch I did I used 6 clones. This way only took my 8 weeks total and I got just about 4 oz. with just my 250w HPS.
I think that for closet grows this is the only light that makes sense. You can get it down on the plants better than a 400 because it doesn't generate much heat. So for shorter spaces it works well. The only thing I will say is that it DOES matter what hood & ballast you use. I use a sun systems hood and it efficiently disperses the light. I have seen some cheap lights with the crummy little reflector and I don't think that would work.

A Magnetic coil 400w HPS will use 456 watts of electricity every hour. That's 5.47 kw per 12 hour light cycle. Work it out from that.
i no i did it to with cfl i got just over 9,oc dry from 4 plants and 2x25w 4x20w 1x30w cfl and a 40w ft lights. and im just about to put 4, 27 day old plants in a smal box room its 3x2ft by 5ft hi, its got a 400w hps and 4 25w cfl in ther, for flowering,,

I'm sticking to my original opinion. For a 3x3 space a 250w light is IDEAL. Heat becomes too much of an issue with a 400w. I would say that under 10sq ft. you don't get much use out of 400 vs. a 200. I will try my next grow with my 400w and let you know how much of a pain in the ass the heat is and if I get more yield. I will have to try to find the same clones at the store though to make it fair.
