cklskypilot Posted February 13, 2011 Share Posted February 13, 2011 Does any one heard of using a sodium for growing corals. They say its closer to the sun then any other lights out there for growing plants. Is this also the same for corals. Quote Link to comment Share on other sites More sharing options...

Michael7979 Posted February 13, 2011 Share Posted February 13, 2011 If someone had a link to this I would check it out. Sounds interesting and worth reading. Quote Link to comment Share on other sites More sharing options...
stylaster Posted February 13, 2011 Share Posted February 13, 2011 I bet it would work fine, but the colors on the coral wouldn't be very pretty. Closest to sunlight is 5500k, very yellow color in bulbs Quote Link to comment Share on other sites More sharing options...
TheGooseWhisperer Posted February 14, 2011 Share Posted February 14, 2011 From what i have heard the growth is good, but the colors are pretty brown/dull. Algae growth would be worse than usual too. Quote Link to comment Share on other sites More sharing options...
dsoz Posted February 14, 2011 Share Posted February 14, 2011 The biggest problem with sodium vapor lamps, if they are low pressure type, is that they produce a vast majority of their light in two very close wavelengths (spectrum color lines) that is just under 600nm (a yellow color). For photosynthesis to work well, it needs more than just yellow light. It also needs the blue and the red light for different processes. If they are high pressure sodium vapor lights, there is a larger variety of colors that are produced, and do include the reds and blues that are needed (make a more "white" light). From the looks of the spectrum found here http://en.wikipedia.org/wiki/Sodium_vapor_lamp the largest intensity of light is found in the green, yellow, and orange areas of the spectrum, with a little in the red, and not a whole lot in the blue area. Again, not the best for photosynthesis. Sodium vapor lamps probably don't have that great of PAR rating, but that is just speculation on my part. dsoz Quote Link to comment Share on other sites More sharing options...
PeteRock Posted February 14, 2011 Share Posted February 14, 2011 Interesting question, I was wondering the same thing recently. For certain plants, I know they grow very well under MH, but create much thicker/nicer "flower blooms" under sodium lamps. So I was thinking it they may aid in blooming or polyp extension or somethign like that. But I know little about reefing, and since I never see any sodium talk or related hobby products, I assume someone has already proven them less beneficial than the halides.
