400 or 600 watt hps?

in a space that is 2 and half feet wide by 4 feet. and is about 5 feet tall. How big of a hps should i go? and how many pots could i get in there? i was thinking of 6 about 10 inch pots, so there would be room for fans and other equipment.

Bigger Always Better, Just Watch And Consider Heat Venting Issues.

400w would suit u better them 600w would get very warm for your grow space ya have 2 take away about foot in hight for the reflector and the pot size 400w suit u better

600 W HPS all the way. the more light the better!!!

im going to have to go with shoot2kill i think that the 400 will be better for you.

i think that too

go for 2x 250 W....and make sure they conversion ballasts!that way u run 1 hps bulb and 1 mh bulb...get a better spectrum of light going and heating is releatively minimul.u also get better coverage of the crop as there are now 2 bulbs instead of the one.also look into ScrOG if you go for the 250W's.u'll get a better yield for less plants....
