Ipana (lux = lumens / area illuminated in square metres). For indoor use, higher lighting efficiency produces more lumens per unit of area with less power and less waste heat. LED grow lights use very low power and are usually engineered to produce monochromatic light matching the highest absorption wavelengths of plant photosynthetic reactions. This design optimizes photosynthesis for a given quantity of input power, as opposed to fluorescent lights which only provide a portion of the desirable spectrum or incandescent and gas-discharge bulbs which also produce only a portion of the optimal wavelengths and, in addition, waste significant energy in 	Growroom

Light-emitting diode (LED) lamps have replaced high-intensity discharge lamps (HID) as the most efficient devices in terms of Lumen (unit)s of light output per unit of power input, but are not yet as widely used. Continuing improvements in lifetime cost per lumen, long life power supplies, and banked or multi-LED fixtures are making LED lights more suitable for large-scale plant lighting. Compact fluorescent lamps are less efficient than LED or HID lamps, but run relatively cool and are widely available in simple fixtures and therefore continue to be used. Traditional fluorescent lamps 	Growroom

Fluorescent and compact fluorescent lamps are excellent light sources for young plants (seedlings). They are also used to supplement the light generated by primary HID lamps. Ventilation. As a controlled environment, grow rooms offer many advantages over outdoor alternatives. However, without adequate ventilation, the plants may consume resources, like oxygen and carbon dioxide, faster than they can be replenished. Adequate gas exchange is necessary for optimal plant growth. Ventilation is also an important method for maintaining an optimal temperature for plant growth	Growroom

Cultivating marijuana is illegal in many countries, and thus some choose to grow marijuana indoors in an attempt to conceal their activities. Law enforcement authorities attempting to locate grow rooms are known to search the records of electricity providers for signs of excessive electrical consumption and employ air or ground vehicles using thermal imaging cameras/FLIR/infrared cameras) to detect unusual instances of excess heat radiating or otherwise escaping from buildings. Growers respond to the 	Growroom

Growroom A growroom (or grow room) or growth chamber is a room of any size where plants are grown under controlled conditions. The reasons for utilizing a growroom are countless. Some seek to avoid the criminal repercussions of growing illicit cultivars, while others simply have no alternative to indoor growing. Plants can be grown with the use of grow lights, sunlight, or a combination of the two. Due to the heat generated by high power lamps	Growroom

The wintergreen flavored toothpaste (0.243% sodium fluoride was its active ingredient) reached its peak market penetration during the 1950s in North America. Marketing of Ipana used a Disney-created mascot named Bucky Beaver in the 1950s. Introduction and early popularity. Ipana was introduced in 1901 by the Bristol-Myers Company of New York. Ipana was an early and large sponsor on United States radio broadcasts starting in 1923 with the program The Ipana Troubadors". A series of popular records was issued under that name by Columbia from 1925 through  1931. Sam Lanin was the leader and contractor of the studio group. From 1934 to 1940, the brand sponsored "The Fred Allen Show", which ran under the names "The Hour of Smiles" and "Town Hall Tonight". After Allen switched sponsors, Ipana sponsored "It's Time to Smile", with Eddie Cantor and Dinah Shore. With hexachlorophene. In 1959, Bristol-Myers added hexachlorophene to Ipana toothpaste. Television ads at that time proudly proclaimed that this ingredient made Ipana superior to competitive toothpaste brands in germ-killing power. It was not known at that time that hexachlorophene was dangerous, and so, the ingredient  was later removed. Magazine promotions. In the 1950s, Bristol-Myers saturated women's periodicals with a broad-based monthly ad placement campaign for Ipana. Magazines such as "Better Homes and Gardens," "True Stories," and "McCall's" were targeted to cover the broad range of women's interests; however, the campaign all but ignored men's magazines, and this weakened the brand by leaving perceptions that Ipana was a product for women and children. Brand decline and withdrawal. Sales of Ipana declined throughout the 1960s and into the early 1970s, due to: Bristol-Myers withdrew many of its basic care products , including Ipana, from the market. By 1979, Ipana had been discontinued entirely in the United States, but it was still being sold elsewhere in the world. Ipana was never submitted to the American Dental Association's Council on Dental Therapeutics for possible acceptance by the ADA as an effective decay-fighting dentifrice. Revitalizations. In 1986, a gel version of Ipana containing two fluorides was introduced in Turkey. At present, the Ipana brand is a leading toothpaste in Turkey. In 2005, River West Brands, a Chicago-based brand revitalization company, re-introduced Ipana into the U.S. marketplace. River West Brands divested  itself of Ipana by selling the brand and related IP to Maxill of Canada in October 2009. Maxill, one of the top three selling toothbrush makers in Canada, brought Ipana back to life in early 2011 as a "retro brand" in the professional dental market, where Maxill had come to dominate the professional oral hygiene category. Maxill extended the Ipana name to other dental products such as prophy angles, topical anesthetic and bamboo toothbrushes. According to the label, its active ingredient is sodium monofluorophosphate (0.76% w/w). Television ads. Bucky Beaver (voiced by Jimmie Dodd) was the marketing icon and  mascot of Ipana commercials from the 1950s. Bucky Beaver's slogan was "Brusha, brusha, brusha. Get the New Ipana—it's dandy for your teeth!" Mr. Decay Germ, stylized as D.K. Germ, was the villain in the Ipana toothpaste commercials. In the commercials, Bucky Beaver told him, "Mr. Decay Germ, stay away from me. I'm sick and tired of cavities. Go bother someone else now." Comic strip ads. Stan Drake, artist of the newspaper comic strip "The Heart of Juliet Jones", started his career as illustrator for the comic strip ad agency Johnstone and Cushing. In an interview with  Shel Dorf for the National Cartoonists Society he said he learned drawing pretty girls on the Ipana ads he did for them. In popular culture. Under the name Frances Westcott, Frances Bergen, wife of ventriloquist Edgar Bergen and mother of actress Candice Bergen, worked for the Powers Modelling Agency, and her face appeared as "the Ipana Girl" in toothpaste ads in magazines. Before becoming a counterculture beat poet, Allen Ginsberg worked on the "Brusha, brusha, brusha" campaign as a market researcher. The jingle is referenced in a scene in the 1978 film version of the musical "Grease" (which built upon  a passing line mentioning Bucky Beaver in the original stage musical), and subsequently appeared in a live televised version, for which the production acquired the performance rights. The toothpaste is mentioned in the 1999 movie "Blast from the Past". A family mistakenly lives underground in a fully stocked private nuclear bomb shelter after a jet plane crash during the Cuban missile crisis. Decades later when they emerge, their supply of discontinued toothpaste is evidence that they really did live underground for so many years. "Bucky Beaver" is the nickname favored by detractors of WWE Executive Vice President [Kevin Dunn], who  has a noticeable over bite and large front teeth.
