Good Day Oldtimer,
First the waiver, different people will have different opinions.

I dont know you situation however I grow inside my house in a 4x4 grow tent inside a small room (lung room). I run two small humidifers in my tent operated off an Inkbird IHC-200 Humidity controller. I generally try to use the ambient temp of my lung room if possible and adjust the humidity controller to zero in on VPD when possible. I do this while still trying to stay within the particular RH range for the stage of growth. When getting into flowering stage I remove the humidifiers from tent and run a dehumidifier with its own built in controller in my lung room and often times run another(also with its own built in controller) in my house (small rancher) to achieve proper RH in my grow tent.

Good Luck
