Thanks for the advice. The plants seem to be doing ok with the heat being built up in the different areas. Although, they are currently not in a climate controlled area (AC) and are around 78-82 in the flower chamber, and 85-89 in the mother chamber right now at or near the top. lower of course lower in the chambers. I am going to try to open up a little more airflow by changing the direction and the location of the exhaust fan...Dayton 265cfm blower. Too big for thet intended purposes by about 1/4" so had to adapt a little. Fan seems to be a little noisy as well...?? Have you had this issue??? Thanks again for your time and patience with a newbie
