The Bigger the Plants get, the more HUmidity they transpirate.Is the HUmidity only in your tent=? or into your area so high=? I would place the dehumifidier in the Tent. And if its only in the tent so dampy, give a circulation and a good airflow, maybe its possible to open the tent=?
If the Humidity is everywhere so high, keep the tent close and Put the dehumidifier inside.I wont use the ioniation function . dont see any good effects here
