Fabric pots come in different sizes. You can select different plants depending on their sizes. In a 3-gallon pot, you can grow plants like pepper, peas, lettuce, and more. The 5-gallon fabric pots are ideal for growing vegetables like potatoes and tomatoes. These bags work also well for herbs, flowers, and small fruit trees. If you want to grow relatively more vegetables, bring 10-gallon-sized pots. These fabric gardening pots are great for cultivating salad greens and spinach. A big grow bag will really work as a small garden!
