Coco coir & peat mossĬoco coir and peat moss are fine fibers, which provide the main structure of these types of mix. There’s no inorganic matter like sand, silt, or clay involved, which means that the mix technically isn’t soil.Įach component of the soilless mix serves a purpose. Soilless potting mix might look like soil, but it’s actually just a mix of organic matter like peat, wood chips, or coco coir, perlite and/or vermiculite, and often a slow-release fertilizer. This might be a loose mix or plugs bound with something like a polymer ( FlexiPlugs are an example of a polymer-bound plug, while some peat plugs are simply contained in a thin baggie). If you’re an indoor grower, you’re probably using a soilless potting mix in some way shape or form.
