Papa_Tanswered grow question 3 months ago I have a Noma 50 quart dehumidifier and you set the humidity value you want and it will do its thing to hold that RH. It does have an led display but that can be covered up with some black paper and tape. I picked it up for 400 bucks.
I don’t know what your set up is like but I’m going to mention this. I run an ac unit in my lung room of the flower tent. I thought I would try to run my dehumidifier to further bring down the RH. The tent runs on one plug, the ac had its own plug and the dehumidifier had its own plug. It didn’t work. It tripped the breaker. So AC and dehumidifier plus tent was sucking too much juice. I can only run one or the other. Both just doesn’t work. That’s a heads up from my experience.
