On Friday, billionaire entrepreneur Mark Cuban acknowledged that he and the other Shark Tank investors missed a major opportunity by not backing the Tree T-Pee, a water-saving farming invention pitched over a decade ago.

What Happened: The product, developed by Florida farmer Johnny Georges, was introduced in Season 5 of Shark Tank as a plastic containment system that conserves water by directing it straight to the roots of young trees.
