Lots of gardeners like the utilize of inert cultivation material when gardening indoors.
Growing mediums can be any number of substances, as long as they allow root access to water and oxygen, are not broken down by moisture, do not contain disease, and could be used by root system for stability they should work. Growth materials could either be natural materials found in the environment or commercially manufactured. Some of the more popular organic materials include perlite, rock wool, diahydro, coir, and wood fiber although there are literally hundreds of materials that could be utilized.
Perlite
- volcanic rock which is transformed into lightweight pebbles through a heating process
- utilized as the only growing medium for plants or combined with dirt
- able to contain a significant volume of air and could be utilized for herbs with roots which require fresh air
- combination of granite, obsidian, pumice, and basalt rocks that have been fused during volcanic activity in a process called Fusionic Metamorphosis.
Vermiculite
- natural mineral that is cooked until it expands into a lightweight, porous pebble material
- usually created in commercial heaters specially designed for the function
- holds more water than air
- has a wicking property which makes it appropriate for transporting water
- so efficient at drawing solution they could sometimes flood root
- if this happens gardeners will normally add perlite to balance out the mixture.
Rock Wool
- one of the many popular growing mediums for hydroponic gardens
- inert compound which is created by molten mineral substances
- fibrous medium and exceedingly efficient in transporting mineral water to root systems. Growers have used rock wool successfully in drainage and recirculated techniques.
Diahydro
- rock that occurs organically in the environment and is a product of the fossilized remains of diatom
- especially useful with species of crops which necessitate high ratios of silica
- can be up to 94% silica that is helpful by plants for developing strong cell walls and structures.
Coir
- also called coco peat
- remains following the removal of fibers from coconut shells. Coco peat is a completely organic medium and does not undergo any manufacturing. It could be utilized by gardeners for lots of different flower types and indoor systems.
Wood fiber
- organic material that can be utilized as a growing medium
- extremely stable medium which keeps its structure for a long time
- care should be taken that it is kept free of disease, pests, or fungus.
Clay pellets
- heated until they expand and become porous are known as LECA, or Light Expanded Clay Aggregate
- useful for gardeners who need to have clean medium that does not hold any minerals
- completely inert, has a neutral pH value, and gives nothing of impact to herbs.
Gravel
- utilized by many gardeners for their indoor growing material
- aquarium gravel is normally used because it is clean and an suitable dimensions
- gravel medium methods can often employ electric pumps and overhead watering systems to ensure a steady supply of minerals
- drains very well, so well that if it is not constantly given with water roots could dry out quickly
Brick shards
- appropriate cultivation medium for a number of varied crops
- similar properties to gravel from a gardening perspective although may change chemical ratios
- can modify pH levels and has to be thoroughly cleaned before each use.
