looks nice! a 400mh/hps?? its either metal halid or high pressure sodium.. the temps high for an attic (not in summer) and the humidity is low for the little fells in there. i'd add a 4" intake pulling cold air from outside into the tent an have the vents open (if light leeking out/in was'nt a problem) if it is then get a 4"fan and carbon filter to match. mh burn alot hotter than hps!! and a 4oowatt hps is more than enough for the space. happy growing and sorry if i sound negative just trying to give you pointers.. my temps have to stay low due to the eye in the sky!!

When he Put MH/HPS he means the ballast is compatible with both

I put a heater in there , because its snowing outside. so i think that's why it may be running hot. For increasing humidity should i just put a bowl of water? would that be enough ?

Looks good, just be vigilant when it gets warmer, that place is going to heat up a lot and fast.

Nice little spot though.
