A great way to add oxygen to your hydroponic system! The Active Aqua Air Stone uses a micro-pore design that energizes your growing solution as it aerates and circulates the nutrient reservoir.
Extends the life of hydroponic solutions, keeps roots healthy and promotes exceptional plant growth. Easy to use, just add an air pump and tubing.
Small (1.7″ diameter x 1.6″ tall)
Medium (2.0″ diameter x 2.0″ tall)
Large (2.0″ diameter x 4.0″ tall)
To increase oxygen levels in a nutrient solution it is much more effective to use many tiny bubbles than a slow stream of large bubbles.
