Large Air Stone's have a porous rock-like design and are great for Deep Water Culture systems or any other hydroponic system that you want to add aeration to. They benefit your plant's growth and yield because the roots get all the oxygen they need from the air bubbles which are producing dissolved oxygen into your reservoir. Your nutrient solution will last longer, it will increase nutrient uptake, you'll have less algae growth, your roots will stay white and healthy and your plant's growth will increase exponentially.
