so I have heard drastic fluctuations in humidity can be bad as far as powdery mildew. What would constitute “drastic”. My humidity has been fluctuating about 8 percent. I’m in seedling stage so I’m running around 73% RH. I’m having a hard time with this humidity staying consistent. It dips down to 66. When I run in the lung room the tent doesn’t get humid enough. But when I put it in the tent it gets too high. I ordered an AC infinity humidifier so it should be better. I’m just curious what’s considered a serious fluctuation
66-73% isn’t a very big swing. Powdery mildew is most at risk when you have high humidity (generally above 60%) and a lack of airflow. I’ve had swings from 30%-60% and the plant takes it. Sure, it’s not ideal, but the plant will still grow.
