never could be too much light unless it causes too much heat. If heats no issue than u can put as many lights as you want as long as ur temps remain sane. The more light penetration the better.

highly doubt you will reach the point of having too much light, but to those who dont know, yes it is possible. It will bleach your leaves. Again, i doubt you will get to this point with your setup though.
 
the real question is how much light u can fit into a 2m2m use cool tubes in parralel and as many as u can fit sounds fun to me

ok so you show a huge wattage fan but what cfm...or is that the cfm and not watttages.

ok room is 200 cubic feet. then need to add for hose lenghts and heat from lights. so about double the room cfm. id at least recomed a 450 or so cfm fan, or id think id see heat issues.

multiply the width by length by hight. that shwos what cfm the room needs. to start with, thhen the lighting and hosing adds more

89 is to hot. not much but is. i dint like goin over 84 degrees.
that dont make sence if you leave the fan on it gets hotter. something not right then. like all them fans are to many are are fighting each other. and what is the 2 inside room..450 ...i dont get the in room part. oscilating is usualy in room fans and the others to exhaust it
seems you have more air goin in than out...needs to be other way around. want negative pressure to keep smells in and remove the hot air. i see this as 300 mm out and 350 going in.
