🌱 Why Choose an Egg Carton? 🍂

Egg cartons are made of lightweight material, usually paper or cardboard, which makes them an ideal medium for seed starting. They are shallow enough to promote good root development and easy for young seedlings to thrive.

🛠️ How to Use the Egg Carton Tray: 🪴

1. Prepare the Carton: 🧴
