Yeah I’m at a cross roads at the moment. Kinda want to try the Kessils because of the kessil logic. As far as I understand it I can run the blue as blue I want and still get full spectrum. Or I might just run a few 36” Orphek strip lights. I bought a used apogee par meter off Amazon this morning. I think it’s super important everyone either rents or buys a par meter. You can watch BRS lighting videos all day and replicate that and still fail. I’m running my 16HD’s currently on their settings for the 40 breeder test they did cranked to 100% so I’d get 100-150 PAR in most of the tank. It about burned my toadstool and it’s got a purple hammer that’s super angry with it. The tentacles are going clear. I backed them down a bit.
