phoenix44 Posted March 9, 2009 Report Share Posted March 9, 2009 hello everyone! :lol: I got 2 new t5 HO's today rated at 54 watts each, 18000K. ive had t5's on the tank before, but this is a 4ft light instead of the 2ft i was using in the past. I know what the kelvin ratings are etc etc, as far as wavelengths are concerned; but what I DO NOT know is what this means for me. are these tubes suitable for growing plants? (i suppose the pants that need lower light will be unhappy) Ive heard that 6500k - 10,000K is perhaps more suited for the propagation of aquatic plants... is this true?

phoenix44 Posted March 9, 2009 Author Report Share Posted March 9, 2009 is that yes for 18000K is good for plants, or 6500 - 10000K is better for plants, or yes to both? Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted March 10, 2009 Report Share Posted March 10, 2009 Don't hit me again boss. Some people use 6500k, I use 4000k and 10000k. I think they are more in the range of those used by mariners. I guess the answer is still yes, or try them and report back. Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted March 10, 2009 Report Share Posted March 10, 2009 My supician would be that it will not be as good as 10000k but have never used them to find out. Quote Link to comment Share on other sites More sharing options...

A-town... Posted March 10, 2009 Report Share Posted March 10, 2009 I run 18000k t5 with a life glo t5 tube cant remember how many K the tiger lotus and every other plant in the tank loves the light. Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted March 10, 2009 Author Report Share Posted March 10, 2009 awesome, thanks man... reason i asked is cause i used to run the same K rating tubes in the 2ft size, and a 15000K and actinic blue and the plants boomed! But I was hoping to replace the whole lot with just the 4ft light hood. I'll see how it goes for a few weeks, and then if growth has slowed down - ill add a 10000K tube.

Yep it would be, the higher the kelvin the whiter, crisper the light. Quote Link to comment Share on other sites More sharing options...
