Originally, fish tanks were operated without covers. After experiencing significant condensation during winter months on the interior of the greenhouse film, additional measures were taken to cover the fish tanks in the winter using a radiant barrier (TekFoil) to reduce the heat and water loss due to evaporation out the top of the tanks and reduce the relative humidity in the hoophouse. The potential for rainwater use was calculated based on the local water data for monthly inches of rainfall, the square footage of the hoophouse, and an estimated collection efficiency of 70%. Rainfall collection potential is reported in Eq. (1) as Lpm. In the equation, RW = rainwater, P = collection efficiency (70%), z = amount of rainfall per month, l = hoophouse length, h = hoophouse height, and times 2 because the hoophouse height is ½ the hoophouse width in this case.
