looking to get some help setting up I have 4 1000 gavitas and will be using a ebb& flow system (total of 3 which does 12 buckets each) so a total of 36 buckets under 4 lights . Looking for some one who would be Abel to help with this and maybe a diagram how I can set this up under 4 lights . And can rock wool balls be used inside these buckets or what's the best option
