I've heard that the best humidity is 40% and that if it's too high you risk mold, but what are the negatives of low humidity? My humidity right now is between 16% and 30%, should get a humidifier? Or will it even make that big of a difference?
You are okay… There are a million things to try and do better. Weed grows everywhere. Don't let water stand around, use fans and an exhaust if possible.
Your plants will be fine in a lower humidity setting as long as your temps are in check. Raising humidity is a lot easier than lowering though. Humidifiers are cheap or you can just leave jars of water in your room. 50-60% is good for vegging 30-40% for flowering
