Free-Circulating AirThese grow bags are made of felt (non-woven, pressed fabric), which has small holes in it to allow the free circulation of air. This free circulation of air benefits the roots of plants by allowing them to more efficiently absorb water and nutrients from the soil. In traditional plastic, ceramic, or clay pots, the roots of a plant will grow out and hit the edge of the container. When this happens, the root system is not being used efficiently, which limits the ability of the plant to pick up nutrients. Plants that grow in traditional pots are also susceptible to temperature shock in warmer weather, due to the surface of the pot absorbing more heat.Self-PruningGrow bags encourage the plants to self-prune. As the root of a plant hits an air pocket, the plant will automatically prune the root, creating a side bud. The plant then develops a solid, fibrous root system, which allows for a greater surface of root hairs. If you wish to transplant some plants that have been previously grown in traditional containers, you can break up the root systems to encourage growth. Some more fragile plants may not do well if their roots are broken up, so make sure you know which plants are intolerant to this.Companion PlantingCompanion planting in grow bags encourages the mixed growth of plants. In a small “ecosystem” such as a grow bag, there are complex root systems as well as a mix of soil microbes in sister plants that will help feed each other.Easy to WaterGrow bags take away the guesswork of watering your plants. There are small holes and pores in the pressed fabric which allow any excess water to drain. While grow bags reduce your chances of over-watering, there is still a risk of under-watering the plants. Since air circulates so freely throughout the grow bag, the soil can dry out rather quickly. Be sure to water regularly.Mobility and DurabilityGrow bags are great for gardens of all sizes, both indoors and outdoors. You can start a plant in a smaller grow bag and move it to a larger grow bag as the plant reaches maturity. Grow bags are predicted to last 7 to 8 seasons, but with good care, they can last for much longer. Grow bags’ fabric is pressed together, not woven, which increases their durability. The bags can be cut without damaging their structure, allowing for the growth not just on the top of the grow bags, but also around the sides of the bag.Starting your own Grow bagStarting your own grow bag is very simple, you will need just a few things:Organic SoilStarter FertilizerWaterGrow BagSeeds or PlantsA location with enough sunlight
