Humidity issues ?

[driftwood]

This Winter I'm doing a little indo . My average humidity ranges from 56%-70% . I'm my first week into flower . Have lots of air and movement with plenty of vent . I was just wondering if I should look into getting a dehumidifer ? And if so what models would be the best for a 4x12 room ? I have no issues in the Summer in this room . This is just the first time runnning through the Winter and want to do all my tweeking now before major flowering or the PM or GM show their faces .
Thanks much love .

Almost any dehumidifier has a rough square foot of what it will maintain, just rememberto empty it.
