Veg room setup

Right now Im trying to convert my tv stand into a veg room it measures's 2x3 ft.Im just not sure what light to use because I already have a 400w hps for my flower chamber,I have been thinking about the 2ft T5 from HTG supply either 2 bulb or 4 bulb whatever I need.It says it puts off 10,000 lumens,so does anybody no if this will be enough light?How hot do these get?Also my veg chamber is only 2ft tall

I'd get the 4 bulb. It should work nicely.

T5s don't get hot, you can keep the plants really close, but they create enough heat to need ventillation...

Your 2ft clearence will be a huge problem though... Thinking, the light will take up at least 5 inches from the top... The smallest container I can think of will take at least 6 inches... That leaves just a foot for the plants to grow...

yeah a foot would work out perfect since I will only veg them to a foot then transfer to the flower chamber.

Yeah, thats gonna be tight as a virgins honeypot. If the plants touch the bulbs for extended periods of time, it will damage them. What will you do if they grow to fast?
Maybe you should consider using singles and mount them in the corners.
