Our flagship product line, Deep Root Irrigation (DRI®), reduces water requirements and improves plant health by delivering water directly to the roots. Its patented new technology enables the units to be embedded below the root zone, then percolate water up to the roots.Deep Root Irrigation also delivers economic advantages. Units cost a fraction of the amount of other irrigation systems, hook up to your existing emitters, and can be installed in less than a minute per unit. The money you save from lower water, fertilizer, and energy costs—and the money you keep by improving plant health even in drought conditions—helps DRI to pay for itself.
