Having a traditional garden in an open, sunlit outdoor space is impossible for most city dwellers. People living in high rises or apartment buildings who want to grow herbs and vegetables indoors increasingly turn to hydroponics, a method of gardening successful in nearly any type of non-traditional setting. Residents of Seattle, WA rely on a hydroponics store not only for the latest supplies, but also for advice and information.

While the name given to this type of production is associated with water, the term is loosely associated with any form of plant cultivation that does not rely on the use of natural soil. The process relies on a wide variety of substitute plant anchors that include porous sands, bits of shredded wood, gravel, and vermiculite. These materials lack nutrients, and growth is maintained by carefully applying liquid nutrition.

Commercial hydroponic operations normally take place inside greenhouses, but the principles involved can be used with equal success in small closets or restricted kitchen spaces. Growers in many countries are not only providing fresh produce, but are increasingly providing cut flowers for the floral industry. In states where personal cannabis cultivation is now legal, the method is ideal for producing healthy plants.

One of the main obstacles to outdoor gardening is the constant presence of pests, and the need for control. Hydroponic systems virtually eliminate the damage that comes from most soil-borne insects, as well as fungi and plant diseases that can spread readily in an outdoor environment. There is no threat from small creatures intent on devouring delicious garden produce. Climate control becomes far simpler.

For beginners, getting started is not complicated or difficult. Basic setups are available online or at traditional shops, and do not require a large financial investment. The main requirement is a space large enough to safely house a structure capable of supporting both plants and their liquid nutrients. While these systems can be complex, they can also be as simple as a grow light and carefully stacked trays.

There are several types of designs for delivery of water and nutrients. Drip systems are popular, and some gardeners prefer ebb-and-flow nutrient film processes, or aeroponic and wick methods. Starter kits are readily available, and can be adapted to fit a particular limited space. Because the nutrients required differ from those in traditional soil fertilizers, beginners usually opt for an existing commercial brand.

There are a variety of materials used to anchor growing plants, and each one has advantages. None are considered superior to the others, because successful results also depend on environment and individual attention. All systems require adequate water circulation to prevent stagnation and malnutrition. Many experienced growers include aeration pumps to aid delivery of nutrients, and most setups require a specific type of light.

Stores that feature hydroponic systems provide consumers with more than quality merchandise. Most offer tips on growing organic produce that is nutritionally equal to the field-grown varieties, and can recommend plants are most ideally suited for a particular indoor gardening situation. Hobbyists are limited only by space and the amount of time available for gardening.
