Yes 4 up matey and about to stick the white chem and bronson in to germ and that'll be me.. 6 new rockwool plants.. im gonna do a bit of a mix to see what size plants I get so I know what I can use in a flood and drain tray in my size of tent.. so it'll blocks on blocks.. pots of mini cubes.. and blocks on half pots of mini cubes.. of the top of my head.. if any other variations spring to mind I'll have a rattle at it. My 2 grodan lecters are lookin sweet all things considered but they're so tall that I already know even a 2L or 3L pot of croutons is gonna grow too big a plant for me.
