Oops! Sorry guys and gals, I found a better deal and decided against the 400W HPS. I found an air cooled cylinder with reflector for a decent price at the same store, so all we need to decide on is bulb size. This cylinder accomodates all HPS bulbs and most MH bulbs too. Now, we found fans for around $35-45 that will push a max of 500cfm and is only 2.5 somes (very little noise). This could possibly mean that we could use a 600W HPS bulb and STILL keep the temps down while keeping the light somewhat close to the canopy of the plants. If 256cfm is required for 1000W HPS we may could even try using this bulb and still be ok on the temps, not sure though, I am sure we will learn as time goes by. Anyway, thanks for the comments and info...keep 'em growin'!

Peace!
