Been following for quite some time now and i am very impressed. i have only one question....are u using tap water and if so what is your tap water like down under?
Forgot to mention will b using an inline turbine type blower and pulling thru a high flow carbon filter. in summer it will exhaust out a window and in winter will exhaust indoors .....if u pay to make heat u may as well us it eh??
simple question.......how much ventilation would b required for a setup that would rely on pulling a slight vacuum to compensate for small air leaks? the volume of the space is roughly 700 cu ft
