Dehumidifier suggestions?

I’ve got a granddaddy purple going in the closet I always grow in, and the buds are starting to dense up. It’s about halfway right now. When I open the door when the lights come on, the humidity is typically over 70. I read these are susceptible to mold and rot if the humidity is to high. Any suggestions for a small dehumidifier I could purchase to lower humidity during lights out? Something someone uses that they knows works.

You need to dehumidify the air coming into the room. Not the air in the room.
Any air coming in is still going to be high rh. Making the air in the room humid and the dehumidifier running constantly raising temp in a small space just making your problem worse. Higher temps higher rh.
Is this a totally sealed room? No exhaust? That's the only way I'd run a dehumidifier in the actual room. And really if it was sealed I'd be running an ac keeping temps low and in turn that would lower the rh.
I have 3 dehumidifiers.
One runs always set to 40% in the basement. Drains right into the floor drain from a hose. The other is set to 50% in case the first one were to fail or one can't combat the rh% the third...well thats a fail safe/drying room unit.
That way the air getting sucked into the tents is around 40%
