About This Heavy duty construction – 300 gm thickness, BPA-free, non-woven material – Reinforced X-shaped stitching on the handles – Multi-layer overlock stitching on the base Fabric grow bags are an improvement on regular potted containers They breathe better – Unlike plastic potted containers, the fabric used in grow bags allows air to reach plant roots. This encourages “air pruning” which prevents the plants from becoming rootbound. When the roots touch air, they make new root tips instead of putting energy into longer roots which will eventually choke the plant. They drain better – Since water can escape in any direction grow bags are hard to overwater. They have better temperature control – Improved airflow keeps the roots cooler in the summer. The insulating fabric can keep the roots warmer when the temperature cools down.
