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.

Root rot is a condition in which anoxic conditions in the soil or potting media around the roots of a plant cause them to rot. This occurs due to excessive standing water around the roots. [ 1 ] It is found in both indoor and outdoor plants, although it is more common in indoor plants due to overwatering, heavy potting media, or containers with ...
Without the sun, your plants are essentially in the dark. Most indoor hydroponic gardens need full-spectrum LED grow lights, which provide the light wavelengths plants need for photosynthesis ...
A major limitation of hydroponics is the fact that 1 kilogram (2.2 lb) of water can only hold 8 milligrams (0.12 gr) of air, no matter whether aerators are utilized or not. Another distinct advantage of aeroponics over hydroponics is that any species of plants can be grown in a true aeroponic system because the microenvironment of an aeroponic ...
The corky root rot became one of the most serious diseases of tomato because growers used the inoculated soil without any type of disease management. [10] For instance, this occurred in Sweden when monoculture of tomatoes resulted in a yield reduction of 30-40%.
Root rot is the most common cause of death for houseplants but keeping houseplants too dry ("under-watering") can also be detrimental. Plants require nitrate , phosphate , and potassium to survive, as well as micronutrients including boron , zinc , manganese , iron , copper , molybdenum , and chlorine .
Pythium-induced root rot is a common crop disease. When the organism kills newly emerged or emerging seedlings, it is known as damping off, and is a very common problem in fields and greenhouses. [2] Thus there is tremendous interest in genetic host resistance, but no crop has ever developed adequate resistance to Pythium. [3]
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.
