Growing Media

We've chosen our favorite growing media for starting seeds and seedlings. We've had the most success with grow cubes & covers, plugs, & block covers. Due to the cost of shipping we do not offer soil, coco, or other types of growing medium in our online store. However, our retail stores do stock and sell Canna Terra Professional, Canna Coco, FoxFarm Ocean Forest, Happy Frog, Sunshine Advanced Mix4, Pro-Mix, and Canna Aqua Clay Pebbles.
