As environmental awareness continues to rise, the issue of post-processing for rock wool has become more significant. Peat, although commonly used, is a non-renewable resource in the short term, and its overuse has been restricted. Additionally, the uneven distribution of peat resources has led to increased transportation costs, especially from the northeastern production areas to southern regions where usage is high. This has pushed attention toward various organic waste materials. Organic waste used as growing media must meet certain criteria: first, the total nutrient content after fermentation should generally be below 4% (N+P2O5+K2O on a dry basis). If it exceeds 4%, it falls under the category of organic fertilizer. Second, the material should remain stable for over a year after fermentation. Third, the EC value (electrical conductivity) should be below 4, and the water absorption rate should be above 2. Moreover, the raw materials should be low-cost and widely available. Examples include cottonseed husks, pig manure, cow dung, rice husks, slag ash, sawdust, and mushroom-growing residues, all of which can be used to create organic ecological cultivation substrates.
Although organic ecological growing media have only recently gained attention due to rising environmental consciousness, they are now being developed more seriously. These media are typically made by fermenting organic waste, often with the addition of functional bacteria, such as Jinbao fermentation aids. A small amount of peat, vermiculite, perlite, or other mineral materials may also be added to create a non-toxic, renewable medium suitable for modern horticultural practices. The key to developing these organic ecological media lies in creating a product that has stable physical and chemical properties, uses easily accessible raw materials, is cost-effective, environmentally friendly, and scalable for commercial use. Using various organic wastes to produce soilless organic media not only helps solve waste disposal problems but also provides sustainable alternatives for soilless farming, enhancing the overall utilization of natural resources and delivering both ecological and social benefits. Economic returns are also considered. For instance, many flower producers in China have started using Jinbao fermentation aids to turn sawdust, bark, and other agricultural waste into ecological growing media, achieving excellent economic results and gaining widespread support.
