Pumps and Nutrient Heaters
Water pumps and air pumps are essential for hydroponic / airponic / aquaponic systems. They give your plants essential nutrients and oxygen as they grow and develop.
Water heaters have adjustable temperature settings to keep the nutrient solution at the correct temperature, ensuring efficient nutrient uptake and good root health. Nutrient solution too hot? Water chillers cool the solution during high temperatures, reducing stress on the roots and the risk of root rot. Find information for ideal hydroponics temperature here and here.
Air stones are just a way of aerating your water solution. Click here for more information.
