Holistic

What does Holistic mean? Holistic means encompassing the whole of a thing, and not just the part. Holistic medicine looks at the whole person for answers, not just at physical symptoms.   Holism is the idea that systems (physical, biological, chemical, social, economic, mental, linguistic) and their properties should be viewed as wholes, not just as a collection of […]

Hypochlorous Acid (HClO)

What does Hypochlorous Acid (HClO) mean? Hypochlorus acid (HCIO) is a weak acid that is formed when the chemical chlorine dissolves in water. Hypochlorus acid has strong antimicrobial and antibacterial properties. It is often used as a safe disinfectant to treat water supplies, irrigation systems, and food preparation surfaces. Hypochlorus acid is also used to sanitize water […]

Hypochlorite

What does Hypochlorite mean? Hypochlorite is an ion of chlorite and oxygen used in a chemical formulation most commonly known as bleach. More on Hypochlorite Hypochlorite is a broad-spectrum germicide that has many uses in horticulture. Hypochlorite kills microorganisms on contact and is used as a common disinfectant. It is used to sterilize pots, trays, pruners, and other […]

Hypha

What does Hypha mean? A hypha is a single filament in a fungus that can reproduce either sexually or asexually. A hypha tends to grow at its tip. An external assembly happens during this process, whereby the cell walls are extended. In fungus, the different hyphae are classified into different singular septum cells known as septa. These […]

Hypertonic

What does Hypertonic mean? In a solution which is hypertonic, the total dissolved solutes is greater than the dissolved solutes of another solution. In plant cells, the hypertonic environment would be all solute particles and the solution they are dissolved in, on the outside of a plant cell. An osmotic gradient is the difference in concentration of […]

Hymenoptera

What does Hymenoptera mean? Hymenoptera is an insect order whose member species possess membranous wings. The front membranous wings are larger than average. While they can have some detrimental effects, these insects facilitate plant pollination. More on Hymenoptera Biologists recognize at least ninety families of hymenoptera, with over 100,000 species. The most common hymenoptera are ants, sawflies, wasps, […]

Hygrometer

What does Hygrometer mean? A hygrometer is a device used to measure moisture content and relative humidity in the atmosphere. As humidity is a derived quantity, the measurements rely on other fundamental quantities, like temperature, mass, and electrical charge. Hygrometers play a big part in saunas, greenhouses, industries, incubators, and, most importantly, indoor plant care. Plants growing […]

Hydrotropism

What does Hydrotropism mean? In plant biology, hydrotropism is a plant’s growth response towards water sources. Hydrotropism, which is triggered by plant hormones, can be a positive or negative response, whereby the plant will either turn away from water concentrations, protecting itself from oversaturation, or move towards them, protecting itself in times of drought. Consequently, through hydrotropism, […]

Hydroponics

What does Hydroponics mean? Hydroponics is a method of growing plants without using soil (i.e., soil less). This technique instead uses a mineral nutrient solution in a water solvent, allowing the nutrient uptake process to be more efficient than when using soil. There are several types or variations of hydroponics. More on Hydroponics Hydroponics is suitable for commercial […]

Hydroponic System

What does Hydroponic System mean? In horticulture, hydroponics is a form of agriculture where plants are not grown in soil, but rather in trays or grow beds fed by a constant flow of nutrient solution. A hydroponic system refers to the tools and equipment that are packaged together in order to grow plants hydroponically. Currently there are […]
