In a hydroponic system ultrasonic hydroponic foggers [1] are used to create a fine mist, the individual particle size of which is typically of about 5 μm in diameter. These fine particles are capable of carrying nutrients from the standing water of a reservoir to plant roots. Benefits include humidification and exponentially improved root ...
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 ...
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 ...
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 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.

Semi-Hydroponics (Semi-Hydro or S/H) was the first passive hydroponic technique utilized for orchids, originating in the early 1990s, using Lightweight Expanded Clay Aggregate (LECA) as a medium in solid-bottomed containers, into which one or two, small-diameter holes were placed in the sidewall, setting the depth of the internal reservoir.
Pythium. 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]
Trunk injection/endotherapy is currently the most popular method for control of damaging insects, [10] pathogens, [11] [12] and nematodes [13] [14] [15] in landscape tree care. Endotherapy is the concept when treatments using the appropriate material formulation are carried out from the inside out through xylem translocation in the trunk/stem ...
