I dont mind building one and having a go with it, what are the timings for running one ie on and off times for the pump, and are they true aero as i've got some 50 micron nozzles and a 60 psi pump to run them or do you just use the low pressure spinning nozzles and a mag drive pump. Also what are the water temps and do you use just ph'd water or do i need rooting hormones etc
