Re: Test HPS tegen HPS/MH
Na veel zoeken heb ik het volgende gevonden aan literatuur welke de keuzevorming makkelijker maakt tussen de philips -son t pia lamp en de -son t agro:
The 430-watt Philips HPS lamp is a real workhorse. When burned in a 430 ballast the lamp gives more lumens per watt than standard 400 watt hps lamps. The light also has slightly higher blue content. When used in a standard 400-watt ballast, a slightly higher lumen output and better color range will occur.
These High Pressure Sodium lamps are used in greenhouses to elevate the red, orange and yellow electromagnetic wavelengths hitting the plant. This (along with shorter photo-periods) signals the plant to start producing bloom hormones. Increased red, orange and yellow wavelengths can produce higher yields and more abundant blooms and fruiting sites when quality plant foods and bloom leaf sprays are used.
Indoor gardeners, lacking the Sun, may find that Hps lamps do not supply the necessary amount of blue light to keep plants healthy. Blue light drives photosynthesis, translocates sugars and keeps the immune system working properly. Those growing areas using HPS lamps exclusively in the bloom stages of growth may experience adverse vertical stretching and blooms located only at the top of the plant.
It is suggested to burn a Metal Halide lamp along side of the HPS lamp to increase sugar production and horizontal growth. Increased insect attack in the final stages of HPS only bloom growth may also be experienced. Other options would include using Sunmaster Warm Metal Halide lamps that burn at the 3 thousand Kelvin color temperature range. They have enough red, orange and yellow light to trigger bloom hormones and an ample amount of blue to keep plants healthy and proportional in size.
Beste Prutser, als je het hierbovengenoemde stuk als vervuiling van je draadje ziet, dan haal ik het er graag uit
