4″ Coir Pots are an environmentally friendlier alternative to peat pots. Coir is a sustainable product made from coconut husks. It will biodegrade, adding carbon-heavy organic matter to your soil. The fibres breathe well, allowing good moisture and gas exchange. Coir pots are great for potting on seedlings without disturbing their roots – simply plant the pot right into the soil, or into a larger coir pot. Use with seedling soil or regular potting soil. Coir pots are lightweight and biodegradable.
