Midwest Hydroganics

General Hydroponics Rapid Rooter grow plugs are an organic growth medium made of composted organic materials. These innovative plugs are the preferred starter method for direct seeding, cuttings and tissue culture plantlets, and are perfect for the hydroponic gardener. The Organo Starter plugs are made from a proprietary composting technology and contain natural beneficial fungi from the composting process. These biodynamic plugs enable plants to be transplanted much sooner with less labor, while virtually eliminating transplant shock and promoting maximum root density and growth. All Rapid Rooter plug material is biodegradable and contains no mineral soil particles. They come packed in a 50 cell tray, loose in bags of 50, or mats of 98 . One of the best rooting mediums that we have come across!
