The TerraCycle Plantable Coir Pot with expanding potting mix wafer is the ultimate eco-friendly pot. This pot is perfect for seed starting and transplanting. The Plantable Coir Pot retains moisture, has excellent drainage, and promotes healthy roots for your plants. 1) Use alone or, for best results, place coir pot inside a slightly larger plastic pot. 2) Place unwrapped wafer in pot. 3) Slowly add water while mixing slightly. 4) Plant seed or seedling directly in expanded mix. 5) When roots begin to show, transplant the entire coir pot.
