The IWS Oxy Pot is a one-plant 'Deep Water Culture' (or 'bubbler') system. In this system, your plant's roots are constantly submerged in a nutrient solution which is aerated via an air pump, resulting in exceptional growth rates.
Each kit contains: a bucket (which is filled with your nutrient solution); a net pot lid (for your plant); one air pump; one air stone; and an accessory kit. Oxy pots provide an extremely cheap and effective way to grow hydroponically.
