MaXXima

MaXXima is a high-quality rockwool slab built for cannabis growers pushing performance that want root zone consistency from start to finish. With excellent water-holding capacity and strong structural integrity, it’s perfect for medium to long-cycle cultivations where optimal plant size and high yields are key. Ideal for high-density grow rooms and greenhouses, it distributes moisture evenly across the slab — preventing dry zones and supporting uniform root development. Whether you're growing heavy indicas or tall, stretching sativas, MaXXima will handle the load while keeping your root zones dialed in.
