The invention provides a method for optimal CO2 enrichment for plant production by suspending CO2 tubing in a secured position between both the plant canopy and lighting system within an indoor garden. The method provides for CO2 tubing to be secured to the lighting system of an indoor garden, thus allowing for the CO2 to be evenly dispersed directly over the optimal upper third portion of the plant canopy. By securing the CO2 tubing in the optimal distribution point, the invention also provides a method for users of the CO2 tank “timed release” system of CO2 enrichment to maximize the amount of CO2 over the upper third portion of the plant canopy during the limited time it is released in the indoor garden during the “lights on” portion of the grow cycle. The invention also provides an apparatus for carrying out the method.
