Grow room controlers

Hi Guys,

I’m a new grower and decided to purchase 3 full 9x9 tents. Going to be using two for flowering and one for veg. My question was can I use one controller for all 3 rooms or do I need to have one for each room ?
If you guys have a better way to set my tents or go about it will truly appreciated !

Thanks!!

It is best to control each room separately. Which ever way you go; You are going to have to create a somewhat sophisticated ventilation system.
