Oasis® Rootcubes® Wedge® is an engineered foam medium with a distinctive design that tapers in shape from top to bottom for cutting propagation. Along with optimal air to water ratios for fast, uniform rooting, this unique shape aids in directing roots downward for more rapid development, resulting in greater crop turnover and overall productivity for the grower. Each cell is singulated; therefore, there is no tangling of the fibrous root systems. Easy to separate for transplanting. Get started with the Wedge Tray with plugs included and refill with the plugs or cubes.
