Root Riot Organic Plant Starter Cubes are available in bags of 100 replacement cubes. Root Riot Organic Plant Starter replacement cubes are pre-moistened so they are ready to use right out of the bag.
Perfect for cuttings, perfect for seeds, Root Riot cubes are a propagation medium made from composted organic materials, specially inoculated with micro nutrients and biologically active ingredients to nourish young plants, and to aid root development. Simple to use, these dust-free cubes have a perfect spongy texture which retains the perfect air/water ratio for healthy, rapid root growth—and they’re fully biodegradable! Pro-tip: For maximum success in propagation, be sure to use Olivia’s Gel to stimulate root development. Keeping cuttings and seedlings warm speeds growth and promotes healthy root systems: a Hydrofarm Seedling Heat Mat will warm the root area approximately 10°F-20°F over ambient temperature to improve germination process.
