The AgroMax Pure UV T5 provides your garden with a concentrated blast of UV-A and UV-B spectrum light. Indoor plants, by virtue of being grown under artificial light, have little to no exposure to UV in traditional setups. In many plant species, exposure to UV-B light will significantly boost and cause changes in phenolic compounds, flavonoid pigments, resins, oils, etc.
– Fits all 2 ft. High Output T5 Fixtures, F24T5HO Lamp Type
– 75% UV-B, 25% UV-A output
– 1 year warranty
The AgroMax Pure UV T5 provides your garden with a concentrated blast of UV-A and UV-B spectrum light. Indoor plants, by virtue of being grown under artificial light, have little to no exposure to UV in traditional setups, however, UV light is a powerful bloom boosting light of which many gardeners have yet to take advantage. Scientific studies show that when plants are subject to UV-B light many of their natural defense mechanisms are triggered. Think of it as your plants producing their own sunblock to resist the UV rays. It is exactly this defense reaction which is targeted by many indoor growers. In many plant species, exposure to UV-B light will significantly boost and cause changes in phenolic compounds, flavonoid pigments, resins, oils, etc.
UV light is excellent for increasing yield and bettering the overall quality of your plants, but one has to be cautious not to overexpose their plants. Overexposure to UV light will not have beneficial effects on plants, too much UV light can “sunburn” your plants. When treating your garden with UV light it is always best started with a low dose amount, with the lamp placed further away and with a shorter “on” time duration. Proper protective eyewear and long-sleeve clothing are necessary when working with UV lamps. Different species of plants have different innate tolerances for UV-B light, dependent on where that particular species is indigenous.
UV light occurs naturally in sunlight, however, UV light is nearly entirely missing from indoor gardens. Nearly every commercially available HPS and MH lamp is constructed with UV blocking glass, therefore little to no UV radiation will pass through to your plants. Additionally, LED technology has not been able to produce UV-B light at any significant energetic level. AgroMax Pure UV lamps provide robust amounts of both UV-A and UV-B light and can be a powerful supplement to any garden. Constructed using a special phosphor formula and an advanced glass tube construction, AgroMax Pure UV lamps are able to provide 75% UV-B, 25% UV-A and a very slight amount of visible light. Use AgroMax Pure UV bulbs to get the best out of your garden.
UV levels provided to your garden will be affected by 3 primary factors, the number of lamps used, the distance between the energized lamps and the plant, and the efficiency and reflectivity of the lighting fixture. When used in a single lamp T5 fixture with average grade efficiency and reflectivity the microwatt levels provided by the AgroMax Pure UV lamp are shown below:
Distance From Lamp Microwatts Per CM2 Coverage Area
1′: 440µW/cm² in a 1’x4′ pattern
2′: 170µW/cm² in a 2’x4′ pattern
3′: 95µW/cm² in a 3’x4′ pattern
4′: 64µW/cm² in a 4’x4′ pattern
Ultraviolet (UV) light is a natural part of Sunlight that reaches the earth and is invisible to the naked eye. At ground level, sunlight is approximately 3% UV light.
Light is measured by wavelength units. The wavelength of visible light ranges from 400-700 nanometers (nm), a nanometer is a billionth of a meter. Light waves ranging from 10-400 nm are known as UV light. The Sun is a source of UV light, which is commonly subdivided into UV-A, UV-B and UV-C light. UV-C light is almost entirely absorbed by the atmosphere surrounding the earth. UV-A light measures between 400-320nm, UV-B is between 320-290 and from 290-100nm is UV-C. UV light is measured in microwatts per square centimeter (µW/cm²) “µ” is the symbol for “micro-watt” UV-B occurs naturally in sunlight. Much of the UV-B light produced by the sun is absorbed by the Earth’s ozone layer. However, depending on your location on the globe, the season of the year, and the time of the day UV-B levels can be upwards of 400 µW/cm².
