A grow bag is a container designed for growing plants and vegetables in small spaces, such as balconies, patios, or rooftop gardens. It is usually made of durable, breathable materials like fabric or woven polypropylene, which allows for air circulation and drainage. The dimensions of a 12*12 grow bag typically refer to the width and height of the bag, which can vary in depth. A depth of 8-10 inches is common, but some bags can be deeper. Grow bags provide several benefits for plants, including improved aeration and drainage, as well as better root development. They also allow for easy mobility, as they can be moved around as needed to optimize sun exposure or protect plants from harsh weather conditions. When using a 12*12 grow bag, it's important to choose plants that are suitable for the size of the container and the amount of sunlight and water available. Common crops grown in grow bags include tomatoes, peppers, herbs, and small fruits like strawberries.
