how many led's do i need to grow sps?
I have a biocube 29 and I want to upgrade my lighting so I can add some sps. How many would I need and how do you figure it out, I know they say 3-5 watts per gallon but led's are different. so how do you know?
Thanks |

Well, it depends if you choose to use optics or not, rapid led has 3w leds so the same rule can apply. Also, they have a diy biocube 29 diy led kit here http://www.rapidled.com/servlet/the-...etrofit/Detail
They also have a constant current one which means you can't dim the LEDs down. Hope this helps. |
