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 sistem razsvetljave 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.
V nedavni objavi na blogu James Grouzos iz PL Light Systems pregleduje 10 načinov za vzdrževanje vaših svetilk, tako da boste še naprej imeli optimalno moč PAR, hkrati pa zagotavljali visok pridelek in največjo učinkovitost.
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.
Preverite svojo svetlobno moč s pomočjo merilnika svetlobe, da vidite, koliko svetlobe resnično dobite. To lahko storite po dveh do treh letih uporabe svetilke. Grouzos priporoča uporabo kvantnega-senzorja (PAR-senzorja) za merjenje. Za meritev se postavite na sredino med štirimi svetilkami in opravite meritve na ravni posevka. Upoštevajte, če obstajajo sence, predmeti ali karkoli, kar bi lahko motilo branje. Prav tako se morate zavedati, da je vaš merilnik svetlobe kalibriran. Tako kot drugo opremo (na primer pH meter) je treba tudi merilnik svetlobe kalibrirati, da zagotovimo natančne odčitke. Kako kalibrirati, glejte priročnik za senzor svetlobe.
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.
