How can i lower the humidity in my grow box? The girls are currently in the dark and will be harvested in two days, the humidity spiked at 70% when i checked it 10 min ago, and im very concerned about getting mold..any suggestions on what i can do?
What is the humidity level outside of your box? Increase the airflow in and out of your box but at best, you'll just equalize with the levels outside of your box. Residential-grade dehumidifiers work well for small grows.
