I want to know how much red is actually needed for vegging and how much blue is actually needed for flowering.. I know obviously you want a bigger blue spectrum during vegetative growth, and a higher red spectrum when flowering.. so I want to figure out what minimum of each you need for each cycle..

well I think you definitely need more blue for veg, but I havent even read the whole thread yet.. hopefully we can chat..

take care good times with ur growing !!
