happy 4th everyone first. be safe.
my current setup is 2 4x4x4 grow boxes setup. 1 for veg with a 400w mh inside the box with 12 16w cfls over 17 plants. 1 9" oscilating fan inside with 1 12" fan as an exhaust. its in the attic so it gets around 78degrees.
and
1 for flower 1 600w and 1 400w switchable mh/hps 4" intake fan another 12" fan for an intake. 1 6"inline out. in the basement and gets 84degrees. lights mounted inside and both boxes have flat white as a reflector.

its time to do a little upgrading. thinking a 1000w hps for the flower room. mount it on the outside air cooled. and a good can air filter. and then take 400w put it in the veg. just wondering what you think on the wattage in a room that size? maybe sugestion for a filter. or any other upgrade suggestions.

this will be my 3rd grow both turned out great. first grow 7.5 oz off 3 plants. 2nd grow find out shortly. almost set but look awesome. sorry for writing so much.
