Hi all, I’m in the middle of my first grow and due to the heat I have to keep my reservoir as cool as possible. It's just a rubbermaid 18 gallon container. I have a small prime water cooler and on tank. I was having trouble mantaining the fluids at 65 F. I was able to insulate the Reservoir with Bubble Wrap, it really helps contain the temperature. For all I know this is standard information. CD
