Ok, so who has a nice looking PC Rainbow? I have had two for a year now I picked up as frags. One is getting blasted with 500 par the other 300 under t5 and led. The one under 500 grows thicker stalks and its faster growth, the one under 300 grows thinner stalks but colors up much much better. Here is the 300 par PC Rainbow under blue led and t5. It really took about 10mths to get it this color. I have found it to be really finicky. I would love to see others that have had luck with the color on this guy. Parameters - Temp 79, Alk 8.5, calc 400, mag 1250, sg .026, phos .02-.06 and trates ,3
