50mm Golf Ball Diffuser Air Stone PA Golf Ball Air Stone increases oxygen and airflow in hydroponic systems to boost plants’ nutrient uptake. Affordable and efficient way of improving oxygen levels Can be used alongside airline and pump to create a tank aeration kit Specifically for use in hydroponic, reservoir and bubbler systems in a tank of up to a volume of 30 litres Ideal for use within an IWS System Recommended to use in Deep Water Culture systems to provide the best root growth environment Can be suspended or allowed to sit at the bottom of the water tank Features a 6mm intake fitting Boosts nutrient uptake through increasing nutrient aeration Enhances cell growth Prevents nutrient solution from stagnating, preventing problems and deficiencies Please Note: Ensure you have an airflow rate of up to 5 litres per minute running through each stone. Switching to a ceramic disc may be a recommendation if there is a greater airflow rate. One piece of airline is needed for each stone. Running multiple air stones from one pump will need a manifold.
