I have 2 bannana cakes from ihg one under hps and one under hps that I place in same spot under same lights
As a test the rest of my 30+ plants have been moved around daily in diff spot and diff lights and so stoned no way to track those other then they all send happy
The hps seems to be lighter color leaves and the cod is noticeable darker other then hps being a little bigger
This my second cob run and it was decent but not as dense as hps so I’m trying to find that Happy medium
