Lighting is one of the most important aspects of growing a crop, and just as you would spend money and time to upkeep a car to ensure it runs properly, a apgaismojuma sistēma needs to also be maintained for you to get the most out of it. Grow lights need to be cleaned, re-lamped, and tested to ensure they are still working well. If not, you can run into problems such as slowed crop growth, increased crop cycles, and overall loss in crop productivity, which can lead to lost profits.
Nesenā emuāra ierakstā Džeimss Grouzoss no PL Light Systems apskata 10 veidus, kā uzturēt jūsu gaismekļus, lai jūs turpinātu nodrošināt optimālu PAR jaudu, vienlaikus nodrošinot augstu ražu un maksimālo efektivitāti.
Keep a re-lamping schedule. Lamps used in horticultural lighting do not burn out like household lamps and need to be replaced after so many hours of use. Light output diminishes after every 1,000 hours of use with HPS lamps. Grouzos recommends re-lamping after 10,000 hours of use, which may be anywhere from two to five years depending on how often you use your lights. It is important to note that every 1 percent loss in light equals to a 1 percent percent loss in production, so after 10,000 hours of use, your light output has diminished by 7-8 percent . Decreased lamp output is even more pronounced in sole source indoor applications, where there is no natural sunlight to offset the associated depreciation in light.
Pārbaudiet gaismas jaudu, izmantojot gaismas mērītāju, lai redzētu, cik daudz gaismas jūs patiešām saņemat. To var izdarīt pēc divu līdz trīs gadu gaismekļa lietošanas. Grouzoss iesaka mērījumiem izmantot kvantu{0}}sensoru (PAR-sensoru). Lai iegūtu mērījumu, stāviet pa vidu starp četriem gaismekļiem un veiciet mērījumus ražas līmenī. Ņemiet vērā, vai ir kādas ēnas, objekti vai jebkas, kas varētu traucēt lasīšanu. Jāņem vērā arī tas, ka gaismas mērītājs ir kalibrēts. Tāpat kā citas iekārtas (piemēram, pH metrs), arī gaismas mērītājs ir jākalibrē, lai nodrošinātu precīzus rādījumus. Informāciju par kalibrēšanu skatiet gaismas sensora rokasgrāmatā.
Look for consistency in your lighting. Do all the lamps look to be the same in light output when you look up at them, or do some look dimmer than others? If so, this may mean that you need to re-lamp. Having uneven light output will affect growth and yields.
