A multi-purpose growing medium, CoirProducts GrowCubes are designed to help fast and robust root development. Wrapped in a biodegradable cover, GrowCubes maintain their shape and can be planted in pots or in the ground. With stable EC (electrical conductivity) levels and neutral pH, GrowCubes will hold onto added nutrients and prevent soil acidification. Our GrowCubes are incredibly easy to use – simply hydrate them with water and watch as they expand to provide a healthy growing environment for your plants. They’re also easy to store and transport, making them a great choice for both home gardeners and commercial growers.
