2. Hydroponics - Wikipedia

   en.wikipedia.org/wiki/Hydroponics

   Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in an artificial environment.

3. Cannabis cultivation - Wikipedia

   en.wikipedia.org/wiki/Cannabis_cultivation

   Cultivation of cannabis is the production of cannabis infructescences ("buds" or "leaves"). Cultivation techniques for other purposes (such as hemp production) differ.. In the United States, all cannabis products in a regulated market must be grown in the state where they are sold because federal law continues to ban interstate cannabis sales.

4. Deep water culture - Wikipedia

   en.wikipedia.org/wiki/Deep_water_culture

   DWC, along with nutrient film technique (NFT), and aggregate culture, is considered to be one of the most common hydroponic systems used today. Typically, DWC is used to grow short-term, non-fruiting crops such as leafy greens and herbs. Supposedly, DWC was invented accidentally in 1998 by a legacy cannabis grower who goes by the name of “Snype."

5. Nutrient film technique - Wikipedia

   en.wikipedia.org/wiki/Nutrient_film_technique

   Plants placed into nutrient-rich water channels in an NFT system A home-built NFT hydroponic system. Nutrient film technique (NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels.

6. Cannabis sativa - Wikipedia

   en.wikipedia.org/wiki/Cannabis_sativa

   In hydroponic growing, the nutrient solution is best at 5.2 to 5.8, making Cannabis well-suited to hydroponics because this pH range is hostile to most bacteria and fungi. [ citation needed ] Tissue culture multiplication has become important in producing medically important clones, [ 19 ] while seed production remains the generally preferred ...

7. Plant nutrition - Wikipedia

   en.wikipedia.org/wiki/Plant_nutrition

   Hypoxia can affect the nutrient uptake of a plant because, without oxygen present, respiration becomes inhibited within the root cells. The nutrient film technique is a hydroponic technique in which the roots are not fully submerged. Incomplete submergence allows for adequate aeration of the roots, while a "film" thin layer of nutrient-rich ...

8. Hoagland solution - Wikipedia

   en.wikipedia.org/wiki/Hoagland_solution

   The Hoagland solution is a hydroponic nutrient solution that was newly developed by Hoagland and Snyder in 1933, [1] modified by Hoagland and Arnon in 1938, [2] and revised by Arnon in 1950. [3] It is one of the most popular standard solution compositions for growing plants , in the scientific world at least, with more than 21,000 citations ...

9. Ebb and flow hydroponics - Wikipedia

   en.wikipedia.org/wiki/Ebb_and_Flow_hydroponics

   Detail of an ebb-and-flow system, nutrient-rich water is pumped through the hoses connecting the containers. Ebb and flow hydroponics is a form of hydroponics that is known for its simplicity, reliability of operation and low initial investment cost. Pots are filled with an inert medium which does not function like soil or contribute nutrition ...
