Coco baskets or Or Biodegradable Plant Pots are matted coco fibers that are covered in natural latex. They can be potted up with soil, or soilless media, like perlite, coir and hydroton. While growers can easily use them in the conventional overhead watering method, the coco baskets are ideal for ebb and flow systems. The baskets absorb water and nutrients from the ebb and flow tray. They allow the nutrients to quickly drench the roots, because the water disperses immediately.
