There are various types of Garden Plastic Pot offered by us that are the most common containers for both indoor gardening and outdoor container gardening. Due to the manufacturing process, they can be made inexpensively and come in a variety of colors, sizes, and shapes. These Plastic pots work best for plants that like their potting soil to stay on the moist side, instead of drying out quickly. Plastic isnât a porous material so air movement doesnât occur through the sides of the container. After watering your plant, the Garden Plastic Pot keeps soil moist for a longer time, keeping more water in the root zone.
