A common response and mistake I've made before confusing the envirolights with the $30 lights of america PC work light and similar fixtures.
Also I disagree... EVL in a cab might be good with 1-2 lights and less heat but whats the point for most when you consider that a 96 watt EVL runs 90-100 each and I would have to spend over $1000 to get the same amount of wattage (and less lumens) as my 1000 watt HPS system w/Hortilux. Even with a premium switchable HPS system & cooling thats about 1/2 the price. And with the hood I have and 185cfm fan my fixture runs cooler than my fan cooled 384 power compact system on my aquarium (basically envirolights, 4x96 watt panasonic bulbs). Not to mention single bulb replacement cost vs multiple and the much shorter life span of PC's with a rapid lumen drop with age. I don't doubt you can grow w/ EVL's but with the cost factor... Why spend more money for less??
Too much confusing apples and oranges here. Certain lights maybe best for specific applications. i.e. EVL good for small grow/cabinet and bad for even small grow room. In an aquarium EVL/PC is good for growing less demanding organisms like soft corals but not good for hard corals at the same wattage as a metal halide. But as with many other subjects the argument/debate will I'm sure continue... |
