Plant Light Guide: Glossary of Common Terms

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

Highland Track Light Beam Angle

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.

LED Chip mounted directly to Aluminum Body

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

CFL Light via SnappyGoat

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

Aspect™ Pendant Grow Light

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
