need your suggestions

Its time to order the setup. I plan on purchasing a 600w hps for 4 plants. Ive heard this was enough, ive also heard this would be enough to fill up a m2.
I digress, I have been looking at these lights and they look pretty huge, since im growing in my basement i need to put my ladies in a tent to keep the temps right. Will those huge overheard HPS lights fit in grow tents?

Can anyone give suggestions on a good tent, will i need exhaust fants in the tent or can i just put a reggie fan in there.

PS: Between the 2, HPS and MH, isnt the HPS better for both flowering and vegging if you can't afford both.

Are there HPS/MH combo lights for $250-400?

Sry for all the questions, i am an eager first timer

you could easily grow up to 16 plants with a 600w bulb in 3 gallon buckets. you can use a 600w HPS in a tent but you would need to have an air cooled hood. There are combo lights and conversion bulbs. But if you want to go 'perpetual' then buy 3 four foot two bulb flourescent fixtures for clone/veg and use the 600w HPS for flowering.
