Coast of Maine® Sprout Island Seed Starter

The Char Coir 4" BioPot is designed for the vegetative stage and is equivalent to a 16 oz. cup of substrate minus the plastic cup.

Ocean forest potting soil is light enough to allow for expansive root growth while feeding your plants for the first month, allowing you to slowly add fertilizer on an as-needed basis.

These inserts ensure consistent drainage and performance, making them ideal for both small and large-scale gardening needs.
