Many growers prefer the use of inert cultivation material when planting indoors. Cultivation mediums could be any number of materials, as long as they promote root access to solution and air, are not degraded by moisture, do not hold bacteria, and could be utilized by root system for stability they should work. Development mediums could either be organic materials found in the nature or artificially manufactured. Some of the more widely used organic mediums include perlite, rock wool, diahydro, coir, and wood fiber although there are literally hundreds of mediums that could be used.
Perlite is one of the many widely used inert materials used in hydroponic gardening. It is volcanic rock which is transformed into lightweight pebbles through a heating process. Perlite could be utilized as the only cultivation medium for plants or mixed with soil to lower soil density. It is able to contain a big amount of oxygen and can be utilized for flowers with root systems that require fresh oxygen. Perlite is a combination of granite, obsidian, pumice, and basalt rocks which have been fused during volcanic activity in a process termed Fusionic Metamorphosis.
Rock wool is one of the most popular cultivation materials for soilless gardens. It is an inactive compound that is produced by molten nutrient substances. It is a fibrous material and exceedingly effective in moving nutrient solution to roots. Gardeners have used rock wool satisfactorily in drainage and recirculated methods.
Diahydro is a type of rock that exists organicly in the environment and is a result of the fossilized remains of diatom. Diahydro is particularly helpful efficient with species of herbs which require high ratios of silica. Diahydro can be up to 94% silica which is used by plants for developing strong cell walls and structures.
Coir, also called coco peat, is the material which remains after the fibers are removed from coconut shells. Coco peat is a totally organic material and does not undergo any manufacturing. It could be utilized by growers for a number of different crop types and indoor systems.
Wood fiber is a organic medium which could be used as a cultivation material. It is a extremely stable medium that keeps its structure for a long time. It is an organic substance and so care has to be taken that it is kept free of disease, pests, or fungus.
Irrigation is one of the most crucial design factor of any hydroponic system.No matter the cultivation medium used it is crucial that it supplies sufficient nutrient delivery and drainage for whatever herbs being planted. Mediums are often selected specifically for their ability to function with the watering system being utilized. It is a important that all mediums are thoroughly cleaned and sterilized prior to growing.
