The HydroHut is watertight, what do I care if I spill some water inside?
Research on used HydroHuts it has shown that sitting water between the first and second water-proof floors was left to dry out on its own. Being sloppy with your watering will only hurt you in the end. If you water with a garden hose or watering can and frequently miss your pots and get water on the inside wall of the HydroHut, that water will run down and sit in between the two water-proof floors. Sitting water will eventually cause the frame to rust, even if the frame is powder-coated or dipped in a stainless solution. Furthermore, sitting water mixed with organics will cause the organics to grow molds. A warm body of water sitting between two layers of plastic will attract bugs, molds and can even lead to a bacteria build up. Please be conscious of where you are putting your excess water.
