The Viagrow 45 gal. Fabric Aeration Grow Bags with Handles are durable enough to last for multiple seasons of gardening while creating an oxygen healthy root system for the plant. Designed to allow roots to breathe, these pots stand up well to heavy harvests and can be used for soil or hydroponic applications both indoors and outdoors. The aeration pots' fabric material is made of 100% new polypropylene (PP) and is environmental friendly. Excellent drainage over traditional nursery pots, allowing water to evaporate more evenly. Great for use with soil or soilless media, use with your favorite drip or flood and drain hydro system. Collapsible design for compact storage. Viagrow aeration pots come with handles for easy filling and maneuvering. To avoid tearing the Viagrow aeration pots handles (15 gal. - 300 gal. sizes), do not move using the handles when they are wet or contain heavy grow media. For heavy pots, we recommend moving them using the Pot Lifter. Shipment includes 2 large fabric grow bags.
