Buying Guide: Grow Bags and Plant Nutrients

Round Fabric Grow Bag Planters
The Gro Pro style round fabric grow bags use breathable fabric that gives roots better access to oxygen. Air flow prunes the root structure, and the fabric helps keep roots cool in the heat. Check the 3 gal size against your plant's root space before ordering.

Rooting Enhancer and Plant Supplement
RapidStart promotes root growth and can be used with coco coir, soil, soilless mixes, hydroponics, cloning machines, propagation trays and root drench. CALiMAGic is a soluble calcium and magnesium supplement that will not clog spray lines or drip emitters.

Using These Products Safely
Follow the directions on each label for mixing and feeding rates. Check your plant's needs before choosing a product, and measure your container before ordering a grow bag.
