The submersible pump is essential for irrigating plants when vertical farming on aeroponic towers, as it delivers the nutrient-enriched water directly to the roots of the plants. Once plugged, it is set on an automatic cycle of 3 minutes on and 12 minutes off. That is a total of 4.8 hours of active irrigation per day. #farming #agriculture #gardening #irrigation #aeroponics #hydroponics #vegetables #soilless | Agrotonomy Tower Farms
