how important is the humidity in my grow room? can i get away with 30% or should i get it to 40% to 60%
Going below 40% will stunt growth and cause reduced yield and increase time to harvest. Most people try to keep it above 50%. BUT...it really depends on the stage of growth. Below is a chart for a 3 month hydro grow. Some of it may not be relevant to you. The humidity line both day and night is good for any grow.
