Hydroponic Glossary Of Terms
Have you ever wondered what is involved in Hydroponic gardening? In order to understand how to use hydroponics for gardening you will need to understand the terminology of the various parts. You will notice that some of these terms are similar to regular gardening as well.
B-1. - Also called Thiamine, this vitamin helps plants use stored energy in stressful conditions when they normally could not.
Bacillus subtillus - A species of Bacillus found in soil and decomposing organic matter; some strains produce antibiotics
Bacillus thuringiensis - A naturally occurring bacterium present in soil, which has been used successfully by home gardeners and organic farmers to control certain insects for more than 30 years. When ingested by these insects, a protein produced by B.T. interferes with the insect's digestion, and acts as an insecticide.
Bacteria . - Is a single celled organism belonging to the domain bacteria, in the three domain scheme. It can also be a type of organism belonging to one of the three major branches of. Traditionally classified as one of the five kingdoms, bacteria are microscopic and relatively simple cells. They lack the nucleus and organelles of the more complex cells called "eukaryotes;" however, like the cells of plants, most possess a carbohydrate based. In common speech, "bacteria" still refers also to archaebacteria, although the latter recently have been classified as an independent branch or "domain" of life. There are malicious & beneficial bacteria, so not all bacteria are destructive, but all are characterized by the "slime" they produce once an infection has occurred.
Bacterial soft rot. See Botrytis.
Ballast - The "transformer" of a lighting system, which provides the energy necessary for an HID bulb to ignite.
Basal - At the bottom or base of a plant. A basal shoot is a limb growing near the ground. A basal cut is made at the bottom of a cutting.
Base up lamp - A vertically oriented HID lighting system where the base of the bulb (threaded end) is in essence hanging down.
Basic - (see alkaline)
Beneficials - Alluding to the beneficial organisms that are responsible for the transformation of organic materials into nutrients and other compounds that are used for plant growth. Example: Types of bacteria, fungi, protozoa, nematodes, micro-arthropods, and mycorrhizal fungi.
Biennial plant - A biennial plant lives for two years, with the vegetative stage occurring in year one and the reproductive stage (flowering) occurring in year two.
Biological insect control - In essence, the use of one species of insect against another more harmful insect. Example: Using ladybugs for controlling a heavy aphid infestation.
Blood meal - A type of organic nitrogen that is derived from the drying of livestock blood.
Blossom end rot - A physiological deficiency symptom in which a plant has not been provided the proper amounts of Calcium, which is crucial in cell wall maintenance. This symptom appears as a black water-soaked area on the bottoms of tomato fruit.
Blue Light - (See Wavelength)
Bolting - for a plant to prematurely begin the development of a flowering stalk and, subsequently, seed.
Bone meal - An organic fertilizer made of ground livestock bones that typically contains moderate amounts of Calcium and Magnesium, and relatively high amounts of Phosphorus.
Boron - One of the seven micronutrients, Boron is believed to be involved in carbohydrate transport in plants. Boron also assists in metabolic regulation. Boron deficiency will often result in bud dieback.
Botrytis - Also known as grey mold or the Noble Rot (viniculture). , A fungal disease that is promoted by cool, moist weather. Symptoms appear as water soaked, blighted areas on flowers, stems or leaves with a moldy gray growth, hence the common name. Control by removing all infected plant parts and making sure the plants have sufficient room so that good air circulation is maintained around them.
Botrytis - any of several fungal diseases that afflict plants; commonly called bacterial soft rot or gray mold.
Breeding - The production of animals or plants by inbreeding or hybridization.
Bud - A protuberance on a stem, from which a flower, leaf or shoot develops.
Bud rot - (See Botrytis)
Bulb (lighting) - An artificial light source - a light bulb or tube, the correct term is lamp, but "Bulb" is a more common term for the home user.
Bulb (plant) - A bulb is not a root; it is an underground stem that functions as a food storage organ. Think of the onion-- each layer is a modified underground basal leaf, called a scale, closely adhered to the stem to protect it, as well as store additional food. Plants producing bulbs are all perennials.
