Looking very nice!
I've got pinnatifada growing under some pretty high lights planted in substrate but most leaning against hardscape in the hope they'll attach.
I've only had them in for about a week and a half now but for me it seems that the new shoots are much more copper colored then the older leaves. It also grows more and more compact as it gets settled so high light does the job I'd say..
Frrok have you entered scapes in contests before?
mind taking a look at mine giving me some pointers?

Thank you. I have some pretty intense lighting also but it ramps up and down on a controller. Even the plants up closet to the light source don't appear to red. Definitely very lush though. I was considering extending the high light time. Jut to see what happens but I don't want to deal with algae. No algae right now.
I have entered the iaplc contest before. I'll check out your tanks.
