Left to itself, water goes flat quickly, as the dissolved gases escape. If you’re growing in a hydroponic setup all of the oxygen will escape from your nutrient reservoir in only a couple of days. After that you can actually drown your plants by depriving them of life-giving oxygen!

The solution? Aerating your nutrient solution with an air pump! The Eco Air 4 pump is small and efficient, delivering 253 gallons of air per hour through four outlets—you can keep four different containers of nutrient aerated at once! It’s also oil-free to keep you solutions contamination-free.

Pro-tip: Grab some six-inch or twelve-inch aeration stones and air tubing to complete your setup.
Widely used in hydroponic systems. Convenient to operate without oil or much noise. Cylinders and pistons are made of excellent materials, making the pump strong and durable. 253 GPH, 5 W, 120 V.
