That thing is tiny bro, sorry to say.
It is only a 20 pint (removes up to 20 pints per day) and probably won't keep up in a sealed room.
I had one 30 pint, as soon as I hit flower, humidity went out the roof. I bought a second 30 pint, still touching 70% at peak hours....
Bought a 70 pint, replace a 30 pint. So now I have one 70 pint (5000 sqft) dehumidifier, and one 30 pint (2,500 sq ft) dehumidifier and finally keeping the RH below 50%.
