I hear that grow tents have heat problems.

How would a tent of X amount sq ft have heat issues greater than a grow room partitioned with drywall also of X amount of sq ft?

I have a Sentinel CHHC-1 computer, portable A/C, bottled C02, Humidifier, Dehumidifier, etc for controls, and air cooled lights.

I have a Grow Lab 145L(5x9x6'7) tent coming in the mail am wondering how I might still run into heat issues.
