I have a 48 tent that I'm using to flower. Someone has to be home to open and close it daily. It gets very warm and humid in it. I have fans exhaust and a dehumidifier that run and all zipped up it gets to hot. Next I will be framing a basic wall and splitting that room for veg and flower. Tents are nice but hot. Make sure it's a decent quality or you will need to get inside and cover all those light pin holes where it's sewn. We also had a zipper break but we're luckily able to fix it quickly.
