Just a heads up to everyone. I've looked all over this forum and had to piece together info from several posts.

My setup is the following: Carbon Scrubber (18" long x 6" Diameter - Closed cap on one end and 6" to 4" reducer on the the other)

That is directly connected to the inlet of the 4" Sunleaves Windtunnel fan. I then have a 4" elbow to a 4" to 6" increaser. Then 6" aluminum flexible ducting to the bulb end of the cooltube. After that it's just 6" flexible ducting out of the tent.

My ambient room temp is 75 deg. My tent temp.....75 deg. Have the cooltube 12" off the plants and there is absolutely no heat.

600W will be here on Tuesday. Will let you know how the temps are then. I'm hoping not much difference.
