My girls are about two- three weeks from harvest. Humidity has shot to 70-80°. Got exhaust on high with all fans on high even in dark period. Ordered dehumidifier but won’t be here till weekend. Have I ruined my crop? Anything else I can do?

If you put a baking sheet (or whatever will fit) of charcoal in the tent, uncovered, it’ll do wonders. It will need to be changed frequently though, just monitor the %

Are you talking about regular charcoal briquets or lump charcoal work as good or better?

More Circulating fans may help with keeping bud rot out… (not sure how many you have) If your flowering a bunch of plants, try staggering your watering… all that watering at one time may be driving up your humidity. What is the humidity outside your tent, like in another room in the house? If sm…

I actually found the charcoal trick after a hurricane that knocked out power. Long story short, ever smell a freezer that has thawed? A few weeks of rotating charcoal (and gagging) had if useable again. Bleach and stuff too, but the charcoal did wonders.
