Ariel Roots: roots that are above the soil, usually used for structure Ballast:a device designed to limit the amount of electrical current in a circuit Beam angle:measurement of light’s distribution, larger the angle the larger the distribution

Biannual:plants that need 2 growing seasons to complete their seed to flower to seed cycle Bilateral symmetry:the property of being able to be split into two symmetrical halves Bloom:when a plant produces flowers Bud: little growths at the end or sides of the stem; grow into flowers, leaves or more stem Carbon dioxide:(CO2); naturally occurring gas that plants use in photosynthesis. Ceiling hook: a hook designed to hold a light fixture to the ceiling Celsius: unit of temperature abbreviated as Cº Chip-on-Board (COB):refers to the mounting of a bare LED chip in direct contact with a substrate (aluminum body) to produce LED arrays.

Chloroplast:part of the plant cell that performs photosynthesis Compact Fluorescent light (CFL): usually come in long, tube like bulbs and are ideal for plants that needs low to medium light

Cool light: typically blue or white tones, fall in the range 4000K-6500K Cultivate:to grow plants from seedlings Daily Light Integral (DLI): the amount of photosynthetically active radiation (PAR) that hits a plant over a certain amount of time Dimmable: lights can be this and can have different levels of brightness instead of on or off. Electromagnetic spectrum: range of wavelengths of electromagnetic radiation, part of this spectrum includes visible light Energy efficiency:using less energy while having the same output as before Fahrenheit:unit of temperature abbreviated as Fº Fertilizer: a chemical or natural substance added to soil to give more basic nutrients to plants Flower: the reproductive part of a plant, it produces the pollen that allows for new plants to be formed Foliage: the leaves of plants as a collective Glucose:the main sugar that plants produce in photosynthesis and use to grow Grow light: artificial light source that helps plants grow by offering a wide-ranging spectrum of light Hardwire: does not require an outlet but it immobile after installment High Intensity Discharge (HID): a family of lights that produce light through an energy arc, where energy it pushes through to connect two electrodes High Pressure Sodium (HPS):use highly pressurized sodium which reacts with the electricity to produce red/orange color light Horticulture: the art of growing and cultivating of plants Incandescent: produce light by heating a metal coil or filament; least efficient type of bulb Kelvin: unit of temperature abbreviated as K Latitude:the geographic position North or South of the equator Leaf burn: when a plant receives too much light or spends too long in direct light, this can occur causing the plant to turn yellow and not perform photosynthesis Leaves: where plants perform photosynthesis and release oxygen LED grow light:(light emitting diode) use energy through a semi-conductor to produce light, need more wattage to function than normal LED lights plant light guide

Vita™ LED Grow Light

LED normal light:same as above; will not provide sufficient light spectrum to plants for successful growing Longitude:the geographic position East or West of the Prime meridian Lumen: a unit of measurement for the brightness of light Metal Halide (MH): similar to HPS except these use metals and halides for the reaction in the arc, these produce blue and white light Monstera: a plant native to Mexico and Panama rainforests that is notorious for the cuts and holes in its leaves Mounting bracket:bracket on which to mount something to a wall or ceiling Node: an area right below where a leaf or branch comes out of the stem Nutrients: usually found in the soil and absorbed by the roots, plants use this to survive and grow Orchid: perennial flowers that usually bloom in vibrant colors such as white or pink Outlet plug:how a light will obtain power, is mobile to anywhere near an electrical outlet Outlet timer: a timer that will turn itself on and off saving you time and money on your energy bill Oxygen: O2; naturally occurring gas that plants produce in photosynthesis Pendant:loose-hanging light fixture that hangs by a small loop plant light guide

Perennials:plants that survive many seasons; the top usually dies off in winter and grows back in spring Photoperiod: the amount of time per day that a plant needs to grow Photosynthesis: the process by which plants take carbon dioxide, water and light and convert it to oxygen and glucose Photosynthetically active radiation (PAR): visible light radiation that allows the plant to perform photosynthesis Power supply: supplies power to the light fixture Photosynthetic photon flux density (PPFD): the amount of photosynthetically active photons that fall on a surface of a plant in a certain amount of time Photosynthetic photon flux (PPF):the total number of light photons released by a light source Roots: a structural feature of a plant, it anchors the plant in the soil and collects water and nutrients for the plant to use Seedlings: the first part of a plant that protrudes out of the soil Stem: a structural feature of a plant, it allows the plant to stand up and keeps the leaves as close to the sun as possible Soil:a mixture of organic matter, minerals, nutrients and gasses where plants are located and anchored to by their roots Swag hook: a type of hook designed to hang corded lights from the ceiling

Transparent Swag Hook

Track: a place to mount the Highland light fixture, allows for sliding movement Variegation:the appearance of differently colored zones in the leaves, and sometimes the stems Visible light spectrum:a portion of the electromagnetic spectrum that the unaided human eye can see; between 400nm and 700nm Voltage:an electromotive force usually expressed in V Wall fairlead: allows for custom spacing and directionality of wires

Transparent Wall Fairlead

Warm light:typically red, orange or yellow tones, falls in the 2000K-4000K range Water: (H2O); used in photosynthesis to produce glucose and oxygen Watt: unit of power Sources: https://aggie-horticulture.tamu.edu/wildseed/growing/annual.html www.britannica.com https://www.merriam-webster.com https://en.wikipedia.org/wiki
