Fabric-woven, breathable grow bags have taken the market by storm. No longer should your plants be subjected to tapering root systems circling the edges of a plastic pot. Dirtbags from Maxigrow prune the roots as they meet the edges of the pot, forcing the root system to branch off and form more sub-lateral roots. The result is a more extensive root mass concentrated in an area of the pot with preferable conditions for your plants. Dirtbags are made from recycled plastic, making them better for the environment too!
