Oasis 102 Count Wedge® Tray and Growing Medium facilitates strong, fast root development of vegetative spring flowering plants. Perfect for many perennials and will help you prevent root rot! Due to the unique shape of the Wedge® Medium, transplanting of the rooted cuttings is made fast and easy. Some perennial growers that have switched over to the WEDGE® from a soilless growing mix have results of as much as 30-40% faster crop rooting. This is largely due to the fact that WEDGE® Medium has a cell structure that's very similar to the cell structure of plants themselves.
