<span class="link_user">@Grimgrows</span>, I do have a tent in there, but I didnāt set it up proper just a wall reflecting. I think the white Styrofoam actually reflects better. I just realized today some things to help me keep the pH better, like turning off the drip ring when the roots are already in the deep water. I also have a fan blowing directly at the buckets bringing their temperature down about 5°F.. So much to learn like also keeping the dehumidifier outside of the closet and yes, doing my best to seal that room.
