Metal Halide and no Chiller?

[PoonTang]

I was hoping i could run 2 x 250 MH on my tank with no chiller. Figured if i had to lay out the money for the lights AND a chiller then would just say the heck with it and spend the money on a solaris led unit. Think now i may give the MH and fans a try if i can find a good used setup for the right price now and get the LED in a couple of years when the prices drop.

That would insinuate that I put batteries in my thermometer and check the temp when I did look it would go from about 72 to 88-89 in the heat of summer with no problems it is in the basement with dual 250 and T5 actinics, but this is Alberta can temp can go fron -10 to + 20 in a day
