I'm new to all this but wattage doesn't necessarily mean better plants. Its about lumens per/sf. I just made the mistake of putting a 600w in too small of a space. Got to hot and wilted the plants. Wish I would of gone with a 400w HPS or CFLs. Theres a formula to figure out lumens per sq/ft. So techinally if you got the tube cool enough you could put a 600w inches above a plant like with flouros...you would run into bleaching problems.

Yes, 600w would be too hot even if you were venting it well. I'd go 400w at most, maybe even 250w. As far as distance of light over plants, get it as close to the plants as possible without burning them. Do the hand test. If it's too hot for your hand, it's too hot for your plants. Do you have any air flow/ventilation in that box?

loose the tin foil from the walls and just paint flat white.
also get a fan.
you could always give it a trail run and see what temps get to.
but i think a 600 would be to hot unless you put in good air flo.

it may be.
but it isnt straight and that will cause heat pockets.
just paint flat white, it cooler and the light reflects better because its straight.

yes from a cool tube that will cause hardley any heat.
but still get a fan blowing.
plants need air flo to help remove plant toxins like the wind would outside.
flos are best for vegging
and hps are best for 12/12
maybe just start off with flos and when your ready for 12/12 get a hps and have 2 closets one for vegg with flos
and one for 12/12 with hps.

well just get a 250 hps that should be ok.
how many plants do you have?.
do you have a fan?.

i can say with 100% certainty you can fit a 600watt hps in their on a cool tube with a 250cfm fan cooling it and induce zero extra heat into the room as long as the intake air is 70f or lower.
i run a 39"L X 39"W X 79"H with a 1000watt HPS and a cool tube cooled with a 250cfm fan and it sits 4 inches above my canopy.
i also use another 250cfm fan to vent the room itself and my temps range from 70f night time to 78f day time lights running 24/0

that spot for a 600 is small you can have a coot tube but it is still overkill.a 250-400 watt would do perfect in that spot
