Yeah I don’t really know what to say, I’ve never even once known my humidity for any of my grows. And maybe that’s something I should look into but I haven’t and it hasn’t seemed to affect me that much. I know it’s dry in my house because I can feel it, it’s the winter it’s going to be dry. But I’ve just let it do it’s thing. If you’re looking for the perfect automated grow box it doesn’t exist. Not everyone has experienced success but they’ve tried to find ways around it and it’s worked for some, but not others. You don’t necessarily need perfect humidity levels but it would obviously help if you did. Again I’ve never even known mine, or the temps inside the box. Just have my thermostat set to 22 and that’s what it’s been since Oct/November
