Disc Air Stone - PVC Encased

These PVC encased Air Stone Discs are great for hydroponic system as they produce lots of fine bubbles in a small area increasing the oxygen levels in the water and help circulate the nutrient solution and improve nutrient uptake. When roots are well-oxygenated they can absorb nutrients more efficiently, leading to healthier and more vigorous plant growth.

Suits 4mm tubing.
