I have the harbor freight 10 x 12 and it requires serious cooling in my zone 9 location
it is protected by my house on the north and the west. (So no afternoon sun) I have an evaporative (swamp) cooler which is on a thermostat which is set to 78 degrees. The $300 cooler runs most days because the GH heats up anytime the sun is on it.

in addition to the cooler I have a 1500 watt electric heater which is set to 72 degrees

there is a old product from LaCrosse WS-8610 Wireless data logger
retailed for $80 - can recive up to 3 sensors -
upload Weather data to your PC with Easy COM port connection
which is closed out but available from [HYPERLINK@www.amazon.com] $40

The chart was done with a free charting program from download.com called livegraph

the purple line is the greenhouse the other two are outside thermometers. This is for two nights.

It I also have the Lacrosse "Professional Weather Center" from Costco $80 (look at my post above) which runs with all of the high end software but the data logger is better because all of the other information clouds the picture when all I want is temp and humidity

see the attached temperature chart
