600 w HPS possible in a 2x3x6 area? Overkill?

Hi,
My area is the same size but I haven't started my grow yet,from what I've read and from previous experience I am gonna use a 250w for vegging and depending on temps a 400w for flower,also just with 2 plants and scrog them.Maybe there is a better way to do it so this is just the way I am thinking of going.I guess a 600w would be fine if the grow area can be kept at the right temps.
Best of luck with your grow.

up the room to a 3x3 or 3.5x3.5 otherwise grab a 400 watt.

a 2x3 is 6 square feet. 100 watts per square foot is deffinatly overkill

400 or 600...? 400. You are going to have trouble keeping it cool though.
I would guess you will need to keep the doors open during lights on.
In anything smaller than a 3.5 x 3.5 I would just use LED.
I tried running a 400 in a 2x3x6 (converted armoire) a while back and quickly figured out that it was not going to work. I ended up using some 2 foot fluoro on two levels to do my veg growth. Now I use it to dry half my garden at a time.
If you are dead set on HID... you will need separate air cool and exhaust circuits. Don't try to get away with the carbon filter on top, light below and one exhaust with passive in, it just won't work out well.
You will want a LARGE fan for air cool and/or a source of cool air to pull over the hot bulb.
In the winter, outdoor air could keep it cool during lights on. In the summer you will have heat issues.
2x3x6 is LED/fluoro territory if you ask me. A 400 hid in there will be a fucking headache but you could pull it off with large fans and cool intake air.

Hay man you should be fine 
I have a 31"x31"x5' sativa flowering chamber separated from my main room. I light it with a 600 watt and cool it with a 6" filtered out and a 4" in. That equates to somewhere near 95 watts per. Sativas love high light! Just keep your temps down and the light a bit higher then usual and you will have some huge flowers!

I have a perpetual with many rooms but I have one room at 3x3x6 with a single 400 MH for mid veg and that is 5,000 lumens per square foot which is more than enough for veg. A 400 in 6 square is about 7,500, that is almost overkill for veg.

No. LEDs do not compare to HID in any way when concerned with affordability. With a $300 HID light(ballast and bulb) in order to get the same watts/lumens in LED one would have to spend 3-5 times that. Don't jump on the LED bandwagon.
I would never grow anything without either sun or an HID until it is well proven! I grow coral in various tanks and we experement with differing light sources. Besides the sun HID is the only way. all other light doesnt grow coral for squat and anemones will try to climb out of the water to get closer. With proper lighting an anemone will pick a spot at the perfect depth so it gets an appropriate amount of light. This never happens when the light comes from a source other then HID (or sun) and coral growth is so fast I can take cuttings every month on some of the slowerer growing hard corals such as acropora. I have never grown herb with anything less then 50 watts per sq.ft. of HPS.

Ive got a 600w in the same size tent and it works fine i have an air cooled hood and 6 other fans to keep air moving though, seems to work well for me!

Do you happen to fit in carbon as well? Ive decided on the 400 w but my other main concern is having a carbon filter

Everything he said is true....Also you have to figure in the costs. I tried the same thing, in an armoire, and stealthy like and it was just a big headache. I mean, it worked after I tweaked it a million times.
Cheap digital balast + tube + reflector + decent bulb = $200 Fans were probably another $200 or so and I still had heat issues.
For the same money I could've just gotten a decent LED panel on a DIY light mover or two blackstars. The only thing that stopped me was the yield..I'm just not convinced..(yet) Although I might take a %10 drop off just to not have to deal with the heat issues anymore
