I use 4 RB 1w kit from rapid on my 180 and it's crazy bright. For your 120, you only need the 2 led kit, will be more than enough light.
Is it bad I use 2RB and 1UV for ma 12G? Hehe...
1w or 3w? That's prolly all you need to grow stuff in a 12g if they are 3w, lol
Thanks guys,the ones from Rapid look good but I don't really want to put them together, looking for something ready out of the box. Any more suggestions??
