Active Aqua air stones are an ideal way to add oxygen to your hydroponic growing system. Their micropore design energizes the growing solution as it aerates and circulates nutrients. These flexible stones bend into any shape to deliver air where you need it most, and they also create less back pressure than traditional air stones, which reduces damage to your pump. This one is 48″ inches/four feet in length.
