Metal Halide and no Chiller?

[Chaloupa]

150g with 2 400w halides and 120g with 1 250w halide upstairs in the same room.....had fans over the sumps, no chiller, but then got a heat pump for the house...wouldn't you know it, it is the only room that doesn't actually get cool...it's the furthest from the furnace/blower....so in actuality the heat pump only cooled the room slightly, we have an HRU for humidity....and the tanks did get to around 83ish.....but at least manageable...
