Oasis® Rootcube® growing medium is manufactured in sheet form, with individual rooting cells shaped like cubes. Rootcubes are available in sheets of various configurations or liners that fit conveniently into a standard "1020" plastic tray.
The innovative formula of Oasis® Rootcubes® medium eliminates the necessity of leaching before use. Since its PH is in the proper range, thorough wetting is all that is required to have it ready for propagation. And the medium's uniform cell structure assures proper drainage and water holding to achieve optimum air/water balance. No leaching required!
