Outdoor Hydroponics

Helpful Information About Outdoor Hydroponics

Outdoor hydroponics is certainly a growing trend for many good reasons.  This practical and effective method of growing plants is done without any soil, using only water and nutrient solutions.  Terrestrial plants are able to be grown either in a nutrient solution or an inert medium including gravel, perlite, coconut husk or mineral wool, with their roots.

Hydroponics vs Soilless Culture

The distinction between soilless culture of plants and outdoor hydroponics is often confused.  Hydroponics is a much smaller term than the broad coverage of soilless culture.  When examining soilless culture, the only stipulation is that no solid with silt or clay be used.  Interestingly, sand is allowed however, technically speaking, sand is a type of soil.

While billions of plants in containers are produced every year including trees, forest seedlings, shrubs, bedding plants, vegetable seedlings, vines and perennials, they are in a soilless medium but not considered hydroponics.  Even some plants that are grown in peat bags in greenhouses are often referred to as hydroponics however the medium actually provides some nutrients to the plant so the term is used incorrectly.
