Just google the brand name with the word grow or journal. Then you can see what they do. As far as I'm concerned, fifteen spectrums is probably a gimmick with stuff you don't need. Just look through grow journals in led section and see the real results from growers here. That's what I did before going with the Mars II 400. The company will tell you everything you want to hear, so check real user experience
