A method to expedite the growth of the agave plant by growing the plant tissue from a cell culture in a laboratory utilize incubator cells that are taken from the leaf of an agave plant and grown in a medium containing all the nutrients required for the production of new cells and the maturation of those new cells. The cells are then exposed to photosynthetic active radiation and fed with extra carbon dioxide, causing the cells to undergo photosynthesis and form the sugars that are found in a naturally growing agave plant. These cultivated cells are given an optimum amount of light and carbon dioxide to promote an unexpected and substantially higher growth rate than heretofore achieved.
