Soil Kits For Hydroponics
Even though hydroponic gardening does not use regular soil, there are some plants and some hydroponic systems that do better when a growing medium is used to help support the root system.
The growing medium packs can be purchased just about anywhere that gardening supplies are available. Sometimes, people that want to have a small indoor garden will purchase hydro grow kits that are easy to use, not very expensive, and can be used for various plant types including herbs and vegetables. Usually a hydroponics kit includes the growing soil and other supplies that are needed.
It is important that these soil kits include some type of nutrient mix to feed the plants because there are no nutrients in the medium. If the soil kit does not include a nutrient mix, or if it runs out, it can be purchased separately either online or at a local gardening store.
