The ONA Gel is our most popular product. We spent many years developing a blend of ONA Liquid and various suspension elements to result in a product that has excellent dispersion qualities. The ONA odor neutralizing agents are released in a controlled manner so that every drop of this excellent product is fully optimized. ONA Gel is the bestseller to hydroponics and indoor gardeners. It can be used in virtually any application with dispensers available for low or high volume needs. ONA Gel is available in the following sized containers: One Liter Jar (32 oz) - for general use; just open the lid and place where odors are prevalent. Four Liter Pail (1 US Gal) - dispense with ONA Breeze or puncture lid for light application. Four Liter Jar (1 US Gal) - dispense with ONA Breeze or ONA Odor Stop (higher CFM volume). Twenty Liter Pail (5 US Gal) - dispense with ONA Storm or refill smaller containers. Thirty Liter Pail (8 US Gal) - dispense with ONA Carbon-Air or refill smaller containers.
