Once again, great post - loving all the help.

To begin, I was told the hood I bought was air cooled, however it does not have glass on it... not sure what this means. The 70CFM fan is going to be used in conjunction with other fans, and I was told I could most likely get through the winer without too many heat problems running 2000 watts - it sounds to me like you do not agree with that statement. I live in Northern California, cold nights, rainy days that are generally pretty cold as well. My ventilation is going into the attic, and I am pulling cold air from the heat/ac vent in the floor of the room. I was under the impression the ventilation, coupled with a few different fans would keep the temps down enough... again, it sounds to me like you are reccomending a cool tube or something like that? The pots I currently have are 100sq MM tall, I believe I need to get larger ones. Thanks for the help, really appreciate it.
