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 required.

Originally launched under the name The Greenhouse Project, [9] the Hydroponic Classroom program was created in 2008 to increase K-8th grade students' interest and proficiency in STEM education while understanding the environmental issues of their time: global climate change, efficient use of water and energy, building greener cities, and growing a secure and healthy food supply.

Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
Deep water culture (DWC) is a hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient-rich, oxygenated water. Also known as deep flow technique (DFT), floating raft technology (FRT), or raceway, this method uses a rectangular tank less than one foot deep filled with a nutrient-rich solution with ...
A rotary hydroponic garden is a style of commercial hydroponics created within a circular frame which rotates continuously during the entire growth cycle of whatever plant is being grown. While system specifics vary, systems typically rotate once per hour, giving a plant 24 full turns within the circle each 24-hour period.
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.
Lettuce grown in indoor vertical farming system. Vertical farming is the practice of growing crops in vertically and horizontally stacked layers. [1] It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. [1]
Games can have both of these at once, offering a basic mandatory tutorial and optional advanced training. Tutorials have become increasingly common due to the decline of printed video game manuals as a result of cost cutting and digital distribution. Tutorials can be important since they are a player's first impression of a game, and an overly ...
