First GSC auto grow

fan leaves are almost gone. Trichomes are almost 70% milky in color. I imagine within the next several days, that it'll be time to harvest. Unsure how to go about drying, as I have 3 more plants, at varying stages of growth, in the grow tent. I have several rooms in the basement that I can dedicate as "drying" rooms, only im nervous about keeping humidity in check. We own a water/mold remediation company and have professional drying equipment, however, im thinking it might be too much. Off i go, to research!
