Active Aqua air stones are an ideal way to add oxygen to your hydroponic growing system. The micropore design energizes the growing solution as it aerates and circulates nutrients. Air stones will extend the life of your nutrient solution, help keep roots healthy, and promote exceptional growth.
Flexible stones bend into any shape you need to deliver air where you need it most. They also create less back pressure than traditional air stones, which reduces damage to your pump.
Choose from three versatile flexible stone sizes. This one is 48" inches/four feet in length.
