Messina Seedlingers Start & Sprout Square Pot Small have been designed to provide a perfect growing medium for seeds, seedlings and starter plants while providing gardeners with an indicator as to the plants need for water with just a quick look. These innovative pots change color based on how dry they are, allowing even novice gardeners to easily tell that the pot needs a watering. Their unique, biodegradable composition also allows for roots to easily penetrate the sides of the pot allowing for planting in prepared soil without having to be broken apart. While the pots will last for weeks above ground with regular care, once planted they will decompose quickly and effortlessly. Comes with 3 trays with 6 pots in each tray.
