The artificial solution described by Dennis Hoagland in 1933, [1] known as Hoagland solution (0), has been modified several times, mainly to add ferric chelates to keep iron effectively in solution, [6] and to optimize the composition and concentration of other trace elements, some of which are not generally credited with a function in plant nutrition.

Upside-down gardening is a kitchen garden technique where the vegetable garden uses suspended soil and seedlings to stop pests and blight, [1] and eliminate the typical gardening tasks of tilling, weeding, and staking plants. [2] The vegetable growing yield is only marginally affected. Kathi (Lael) Morris was the first known to grow tomatoes ...
The hydroponic solution alternately floods the system and is allowed to ebb away. A root ball and the growing medium required to grow a single plant. The medium will be washed and sanitized before being re-used. Under this system, water-tight growing containers are filled with a inert growing medium.
Hydroponics is a method for growing plants in a water-nutrient solution without using nutrient-rich soil or substrates. Researchers and home gardeners can grow their plants in a controlled environment. The most common artificial nutrient solution is the Hoagland solution, developed by D. R. Hoagland and W. C. Snyder in 1933.
Due to the plants continuous fight against gravity, plants typically mature much more quickly than when grown in soil or other traditional hydroponic growing systems. [55] Because rotary hydroponic systems have a small size, they allow for more plant material to be grown per area of floor space than other traditional hydroponic systems.
The fundamental principle of aeroponic growing entails suspending plants in a closed or semi-closed environment whilst spraying their dangling roots and lower stems with a nutrient-rich water solution in an atomized or sprayed form. [2] The upper portion of the plant, including the leaves and crown, referred to as the canopy, extends above. The ...
