Grow bags are made of patented, double-layer felt fabric instead of plastic. This felt-like fabric allows for great aeration so your plants will not suffer from heat build-up, overwatering, or poor aeration. Prevents heat build up in the roots due to good air flow coming through the fabric.
Grow Bags have a porous fabric that air-prunes plant roots, resulting in a robust and healthy root system. Can be used for years round!
