Plastic nursery pots are lightweight, durable, and cost-effective containers made from flexible plastic (often PE+PP or HDPE), ideal for starting seeds, propagating cuttings, and growing plants. They retain moisture well, making them suitable for water-loving plants, but they provide poor aeration compared to clay. These pots, featuring multiple drainage holes, are reusable and commonly available in sizes from small starter pots up to 35+ gallons.
