I am not sure it's so much LED, but how they are not being utilized with all channels creating a robust full spectrum. I have noticed all blue spectrum led grown corals look drab when you crank full spectrum. Either way, I feel more hobbyist will eventually figure this out. I wish I had so many corals back from the day, lol...
Gotta find these gems, grow them out, share with a trusted local hobbyist that does the same, then try and make a few bucks. This takes time, and a process that should be enjoyed.
