Closet Design Help/400w or 600w!!!!

OK Growers, so i currently have a closet grow going on and im not sure of the specific measurments but its about 4x1x6 (that i am using as a grow space) the closet is larger than those dimension. Currently i have a 150w hps and 303w of cfls & my conditions are perfect, temps 75f-85f and humidity 45%-60% with jus a fan moving air around.
I plan on upgrading to a 400w or 600w. i do plan on getting a cool tube or a/c hood. My questions are; is a 600w overkill for a grow this size? does anyone have experience with a 400w or 600w closet grow? Any tips on ventalation(there is a panel in the closet for acces to the plumbing for the tub and shower, could i use this to expel hot and filtered air into the buildings structure(i live in an apt.)
THANKS IN ADVANCE FOLKS
HAPPY GROWING

I grew in a space that was 52"x 30"x 72". I had a 400 watt in it temps went upwards of 100 degree's. No cool tube though and I didn't have good a/c. It would have grown really good bud if I would have had quality genetics. Seed's from mexican dirt weed grow's dirt weed. Found out the hard way. Newb mistakes. What kind of ventilation do you have? If you don't have good ventilation I'd go with t5 or led runs way cooler.

I think if it is perfect right now, then I would not go to 600 watt it will be very hot even with a cool tube, however 400 watt may work. If it was me I would think of going to a 250 watt max and see how that goes. just my opinion. Good luck bro.

Ive done a bit of searching and have met a few growers who have done the exact grow with a 600w cool tube. I also found a diy a/c which is sooo simple and cheap. I plan to modify it and get the 600w and keep it cooled w/ the diy a/c system.
Thanks for the input guys, thatnks for concern as well, i am also still somewhat new at this so we are all learning. If this works then it will jus be another tip to past down to others.

You could run a 600 in there but 400 is all you need.
