And other natural composition

Add or remove some composition will effect soil’s moisture-lock capability. To provide ventilation and nutrition, suitable soil plays am important role.
Some soil-free mixture composition, such as peat mixture, is too lightweight for container gardening, and cannot provide enough support to roots. Furthermore, soil-free mixture composition is sterile, barely nutrition. Suitable container mixture composition should be contained with coir, peat, bark, vermiculite and others.
Any growth medium must provide water, nutritions and physical support, and then nourish a healthy plants. A good growth medium must have excellent drainage system, synthetic or soil-free composition mixture, including sawdust, wood chips, sphagnum moss, perlite or vermiculite, are very suitable for vegetable container gardening. These compositions contain no any illness, weed, keeping water and nutritions, and are lightweight.
The selection of manual plant medium is related with the types of plants. Herbs, succulents and all-seasonal plants will grow well in good-drainage soil. If you plant them in containers, choose those growth mediums which contain with barks, sands and perlite.
Leaves and tropical plants need less growth medium as they prefer water.

Find Suitable Soil in Your Grow Bags
Soil is the core of any container gardening, because it is elated with your plant’s growing.
The best proposition of composition using in grow bags should be 1/2 peat moss, 1/3 compost and 1/3 vermiculite, play an important role in keeping moisture. Put 3/4 into a container, slowly shake it by picking handles, and then water to trigger original nutritions. Now, you can start to use your grow bags and composition mixture.
After the growing season was gone, you can reuse the soil mixture, but not include wood mulch. Empty all grow bags and then add 10%-20% new compost and old soil, mixed and use again.
Why Choose Grow Bags Rather Than Traditional Containers
Grow bags are the suitable choice planting various vegetables. If you only have small space, you can use grow bags which are easily distributed and moved according sunlight or water.
Fabric pots are great if you have poor quality soil in your area. The soil mixture you use for your grow bags can help you build an outside garden in the future. Each time you want to throw the old soil from your grow bag, dump it in an area where you plan on having a garden one day. After a few years of doing this, you will have a garden with improved soil quality. Alternatively, you can always reuse your potting mix for several seasons before disposing of it in your outside garden.
There are many other benefits using grow bags:
Movement: Traditional containers are very heavy. In comparison, grow bags are lightweight, and they come with handles which transplant them easily.
Breathablity and Drainage: Compared with other traditional pots, grow bags are made with non-woven fabric material, which means air can reach roots, and prevent over-watering.
Avoid Root-Bound: Long roots will self-circle in plastic or ceramic containers, while in fabric bags, roots will reach into bags’ sides and be pruned by air. In grow bags, pruned roots will grow many small root tips, strengthen themselves. These small tips absorb water and nutrition, and then transfer to roots, final to top plants.
Keep Cool in Hot Summer: Plastic pots are hotter than fabric pots in summer, cannot let the heat dissipate, and plants cannot breath.
