as long as you just get a large enough exhaust sytem i personally could stick a 350 in there. 4 plants trimmed up skinney and tall as fuck. heat will fuck you though without proper exhaust. to keep it cool, find your cubic footage of the tent and you need a fan capable of moving 4-5 times that per hour. mine for example is 80 cubic feet so i need to move at least 320 cubic feet per hour minimum, on mine i put 320 cubic feet a minute just to deal with the extra pull needed for carbon filter and ducting

Your room is 2.3 squarefeet, please review the three levels of recomendation below suited to your grow room
Minimum Lighting 25 watts Per Square FootLighting
The minimum recommended lighting for your area is 57.5 watts
Ventilation
The minimum flow rating of your fan should be 3.8 Cubic Feet per Minute (CFM)
Power Requirements
This setup will require 0.6 amps to be available at all times for safest operation*
The optimum reccomended lighting for your area is 92 watts
Ventilation
For optimum ventilation the flow rating of your fan should be around 4.1 Cubic Feet per Minute
Power Requirements
This setup will require 1.0 amps to be available at all times for safest operation*
The maximum reccomended lighting for your area is 138 watts
Ventilation
Going this way you will require a fan with a flow rating of at least 4.9 Cubic Feet per Minute
Power Requirements
This setup will require 1.5 amps to be available at all times for safest operation*

Getting to these points and or over it is highly reccomended the grower use Co2 in their room as your plants will only be able to photosythesise a certain amount of light before needing a Co2 boost to benifit

The issue with that "minimum lighting per square foot" is that it is all based on watts. Watts and lumens are hugely different. A150 watt hps emits about 16,000 lumens, a 100 watt incandescent lamp emits 1,260 lumens. Big difference there.
Most of us go with lumens per foot, lots of info on here on that.

We are talking about growing pot. I'm not expecting someone asking these questions to run 2000 watts of incandescent bulbs. Lumens have nothing to do with growing - they aren't PAR there's a big difference in that too... they are lumens... look it up.
Lumens are the color of the light as percieved by the human eye... what's that got to do with shit?
Lumens diminish as the light is further from the plant. How do you advise someone on that?
Lumens diminish as the light gets burned. How do you find a constant?
You explain it to me - and maybe I'll understand how you guys think.. I can't think of any experienced growers (at least the ones I know) don't talk lumens. They talk wattage.

Not me.. I have tools.
That is the spit out from a grow room calculator from canniversity.com.
They talk wattage too.

if you have a semi descent LED dont sell it. ya it may not outwork your hps, but since they pull such little wattage you can always use it to keep a mother plant or just for cloneing. you may not see the benefits now, but when your first crop is 3 weeks from done you'll want to start cookin some clones or a mother under there so that your not tryin to start from seed or track down viable reputable clones. thats just what i would do
