Only 3' height? That is not enough. If your talking 3 wide by 4 deep by 8 height, that will be fine, even a 600w would be fine in there, and easier to control heat than a 1000. If 8x4, you will need at least 4-6' I think (you need room for your pots and your light will probable need to be 18" above the top of your plant. Maybe you could do a vertical grow in that space, but man it seems like it would get HOT!
Why don't you start smaller, get a 600 and try only 1-2 plants while you get the hang of it. No need to rush out and try to get a huge grow on your first run, keep it simple, take your time and you can start adding things on subsequent grows. If you don't have the patience to start slow, you probably will end up killing your plants with love because growing is a patience game.

I agree with hbbum.
Judging by this post, you will really want to start small and learn what you can from your first few crops before you go big. People have given you some great examples of what the bigger HPS/MH lights can do here in the right setup. That doesnt mean you cant start out with CFL's or a T5 lamp if you dont have the money to dish out.
Also, is your environment able to handle a HPS light? Those suckers will pump out some heat if you dont have a way to vent it out. That heat in a small room or closet can be a death sentence for your plants if you dont handle it well. CFL and T5 lamps also put out heat, but nowhere near as much as a 600-1000W HPS lamp.
My advice would be to keep everything you learned from this post in your head, but start on a smaller scale. See if you have the patience to grow. You'll learn a lot in your first harvest, and you will keep learning from there on out. Once you get to that point you will have a baseline for your setup, and what you want out of it. Then you can choose what light you really want to run, and get to it
Anyhow, goodluck in whatever you do. Hope this post helped.

Nice plant!!!150 watts on a flowering plant won't yield much, especially if its fluorescent light.
but yes, that plant has pythium and is never going to amount to much.
People should understand that if you are doing things correctly with good genetics, you should be able to turn this
and 10 days later have this:
How many side by side comparison grows have you done?
600 watts of T5 lamps put out more heat than 600 watts of HPS.
600 watts of MH puts out more heat than 600 watts of HPS
600 watts of LED lights puts out more heat than a 600 watt HPS
HPS is THE MOST EFFICIENT growing light you can buy.
Tungsten incandescent efficiency= 15 lm/W
LED efficiency= 98 lm/W
MH efficiency= 100 lm/W
T5 efficiency =104 lm/W
HPS efficiency= 150 lm/W
Some day the new Phillips LED tech might be available, promises of up to 200 lm/W have been proposed, whether that is sustainable is yet to be seen.

My last grow nl
I dont have a lot of experience to pull from, being a new grower. I'll preface what im about to post by saying that.
I would have to disagree with your previous post, at least mostly. Im sure that equal wattage most light types would produce similar heat, barring LED. That being said, the way the heat is dispersed will greatly affect the grow room.
For example, I have an 8 bulb T5 sunblaze light that pulls a bit over 400 watts. The panel is roughly 4ft long by 2ft wide, and has the eight bulbs equipped with spacing between to allow for dispersion. Your typical 400W HPS (http://www.htgsupply.com/Product-HTGSupply-400-watt-High-Pressure-Sodium-Grow-Light) has all that light contained in one bulb in a 9" long x 4" wide x 5.5" tall housing.
If a new grower decided to use a light light that in a small room, and didnt allot for temperature control and venting, I would assume the light would do more harm than good. It may even cause a fire, if the person wasnt aware of the possible heat buildup.
I still stand by my post. OP, do whatever you think is best. Just know that the stronger the light, the more heat you are going to have to deal with.
Also, in my personal experience, a good lower watt LED panel with heatsinks/fans produces practically no heat no matter how long you use it. Im sure that would change as you increase the wattage, but im willing to bet that the temperature range would be significantly different if you side by side compared equal wattage fixtures.
Im not sure what you're trying to point out. The sun will put out more heat, regardless of the temperature on earth. It has a really big room to shine in.
I was just trying to explain to the OP that heat will be an issue, and that he needs to weigh his options. Hes obviously very new, just trying to make sure he doesnt spend a lot of money on something he isnt going to stick with or burn his house down during the grow.
In the first sentence you admit you have no experience, then later you rely on that non existent experience to help bolster your argument that HPS puts off more heat than t5 and LED.
Your 400 watt T5 light puts out more heat than a 400 watt HPS. This is scientific fact. How you "feel" about it is not evidence to the contrary. Just because a localized spot "feels" hotter isn't evidence that its less heat. a 10 watt IR laser puts off more localized heat than a 1,000 watt HPS, but I certainly wouldn't use that example to utilize the theory that localized heat = more heat total being put off, that would be self defeating and an obvious folly.
Do not believe me, do your own research

I imagine that the reason you believe T5 and LED are better and more efficient is because that is what you have. Not an abnormal human response, Chevy vs Ford.
I'm not here to argue brother, just trying to help the OP out. You're right, im still in the learning stages and im sorry if I touched a nerve with you. I stand by my post though. I guarantee I can hold my hand closer to my light, for a longer time than you can with yours. May be the same amount of heat, im not sure. I am sure that yours is more concentrated and in a smaller housing. Fact.
Heat in a small space can cause trouble if you're not ready for it. If you can handle it, go for it. You will probably get better results. Peace.

So what you are saying is that a 400 watt HPS will heat the room more than a 400 watt LED?
Already proven as false, why do you continue to perpetuate false information? Do you want the person to fail?
Concentration of heat is nothing, a 10 watt LASER puts out much more concentrated heat than a 1000 watt HPS, but that doesn't mean its going to heat a room up more. Efficiency is what its all about.

But hps makes plants stretch mh keeps those nodes tight .. IMO because of that u will get bigger longer tighter nuggs using both hps and mh ....instead of unconnected nuggs or smaller nuggs everywhere using just hps...

Lol are you saying an led puts out more heat then hps..lol u should stop comparing hps to Chinese LEDs..

If you want to save cash and use less energy buy a solorstorm 880.. It still produces heat but it's much less then hps... U can run your ac less often.. U save about 40 percent on your bill.. But it cost about 2500.. If you want to save money you gotta spend money!
HPS doesn't cause plants to stretch, old wives tale. Internodal spacing might be a bit tighter with the MH bulb, but the overall yield would be less. If less is more in your book, then have at it.
Watt for watt HPS puts out less heat than LED, CFL, MH. Fact, incontrovertible fact, scientific fact backed up by tons of evidence and measurements.
