O2 Grow is the exclusive worldwide licensee for patented technology that significantly increases the level of dissolved oxygen in water. Bubblers and venturis are inefficient at raising the dissolved oxygen level (ppm) in water. In addition, this process will actually raise the water temperature to match the surrounding air. Bubblers and venturis simply "blow" air through the water. The O2 Grow patented nano bubble technology elevates the dissolved oxygen levels 50% more than bubblers through electrolysis without increasing the temperature of your water. The O2 Grow technology actually "manufactures" 100% pure oxygen. It's well documented that oxygen is needed to help balance pH, prevent root disease and ultimately increase yield. Increased oxygen to the root zone has shown to increase the speed of plant growth, size of the root ball, number and size of flowers, and nutrient uptake. O2 Grow is changing how the world waters plants!
