The O2 Grow system uses electricity to deliver pure oxygen right into your reservoir, not just an aquarium bubbler reformatted for a hydro reservoir. This unique product uses electrolysis to oxygenate water for increased plant growth. High Times did a side-by-side test of the O2 Grow and a traditional air stone bubbler, and found it provided 26% more dissolved oxygen (DO).
Water pent up in closed reservoirs doesn’t have a natural input of oxygen, so hydro growers need a way to reintroduce the oxygen their roots consume to keep healthy plants. For making compost teas you need a supply of oxygen as well, or else the bad anaerobic bacteria will take over.
Traditional bubblers use a noisy and high wattage pump to force air through an air stone, a porous rock that disperses a stream of air into a bunch of bubbles. More expensive air stones, often called diffusers, can be made of ceramic or another porous material like silica. By generating smaller bubbles the air comes into contact the water with a larger surface area, so oxygen has a greater opportunity to dissolve into the water. Because these bubbles provide a slow source of oxygen, they mostly need to be run 24/7. The O2 Grow provides a lasting amount of DO in three, six or ten hours depending on the volume of water.
Regardless of whether a bubble diffuser is cheap or expensive and high tech, it will always have one major limiting factor: air is only about 21% oxygen gas; nitrogen comprises the rest, with just a touch of argon.
This device uses electricity to literally split H2O into hydrogen gas (H2) and.... read more through the link in bio
