You need a mini split. I have 2 and they both dehumidify, and have AC and heat modes. Also they have a hose so you can place into a runoff bucket for dehu water and pump back into your res. 10x10 I would suggest a 2 ton unit. 24k btu . When the AC is not running, ( when lights are off) the mini split is not going to be dehumidifying so you will need a dehumidifier to maintain your humidity during lights out. Good luck
