Stealth I can hardly claim to be an expert either on LED's or Liquid Light so I can only offer the thought that in reading over the literature carefully (which i always try to do) I saw nothing about needing a certain kind of light, lighting, or spectrum. It HAS burned some of my older fan leaves which is something I've seen with other foliar sprays as well but DutchMaster recommends it for "rooted plants" one week old and older so I tried it on my one week old seedlings and they did quite well with it. I will add I was very careful with my lighting on them though. But I'm afraid I just can't help you with specifics.
