Struggling with RH, tent is too crowded bc I have lots of negative pressure, tent is bowing in hard. The best I can get down to is 50%RH, however I have tons of circulation. Look at video. I put a dehumidifier in the lung room. Rh drops if I open window, but its raining. Too wet outside rn. It went from blizzard (dry) to rain for 7 days now, maybe thats why Im struggling. Need circulation in lung room too. Vents open, still struggle, tent door open, im fine. And I use blackout curtains so no light penetrates the room. It maintain complete darkness 24/7. Plants sleep when i sleep, so never worried about it. My house was built in 1952 post WWll, so no insulation, just straight brick and a solid slab. That means it will hold moisture. Lung room at 35% RH. Rearranged set up. Trichomes...... 70% clear, 20-25%% cloudy, 5% amber
