Great air and movement also humidity levels r 35 to 40 But what I have noticed is a heavy calcium deposit on my inside water barrel clean it out all the time happens mostly if I let standing water for a day or two. Tyemp is alaways at 22 c never goes below 20c with lights off .so I am now trying a new salt purifying water softner to see if the helps .now on my outdoors using same recipe had huge success on 20 plants 27lbs so far with my bottoms still to come in this week went I little higher on pppms due to fact im working in a outdoor environment,and 3 by 3 by 3 boxes. Any help would be greatful
