<Disclaimer> I'm no expert. </Disclaimer> I bet it would work better than you can imagine. I'm just wondering how you would control the temperature, seeing as most fridges work around 30-45 or so degrees and each day will be different. having original been from Florida i THINK it may be easier to do as GPSFrontier did and place you
nutrient reservoir in the ground. I know my plans for the summer if it get warm enough to be a problem will be to use some 2 liter bottles frozen full of water just put into the solution bath as reusable ice cubes.
