These two cannabis plants are being grown in a DWC (deep water culture) hydroponic system. They are in the vegetative stage and are being grown in a 4'x4'x7' grow tent under a 600W MH (Metal Halide) grow light. There are many types of hydroponic systems. If the nutrient solution floods the loose growing medium and recedes for aeration, this is ...
Kratky method. The Kratky method is a passive hydroponic technique for growing plants suspended above a reservoir of nutrient-rich water. [ 1] Because it is a non-circulating technique, no additional inputs of water or nutrients are needed after the original application, and no electricity, pumps, or water and oxygen circulation systems are ...
Passive sub-irrigation, also known as passive hydroponics, semi-hydroponics, or hydroculture, [52] is a method wherein plants are grown in an inert porous medium that moves water and fertilizer to the roots by capillary action from a separate reservoir as necessary, reducing labor and providing a constant supply of water to the roots. In the ...
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 ...
Organic hydroponics. Organic hydroponics is a hydroponics culture system based on organic agriculture concepts that does not use synthetic inputs such as fertilizers or pesticides. In organic hydroponics, nutrient solutions are derived from plant and animal material or naturally mined substances. [1] Most studies on the topic have focused on ...
Passive hydroponics, semi-hydroponics or passive subirrigation is a method of growing plants without soil, peat moss, or bark. Methods [ edit ] Instead an inert porous medium transports water and fertilizer to the roots by capillary action .
CEA technologies include hydroponics, aeroponics, aquaculture, and aquaponics. [2] Different techniques are available for growing food in controlled environment agriculture. Currently, the greenhouse industry is the largest component of the CEA industry but another quickly growing segment is the vertical farming industry. Controlled Environment ...
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 artificial solution compositions for growing plants, in the scientific world at least, with more than 20,000 ...
