I get a little cranky when people that have offered help (directly or indirectly) get disrespected, your comment suggests that you haven`t seen any root pics of accumulator based aero or had the opportunity to compare those roots to your own.I have asked repeatedly for plant pics from using an accum, but no one has done so. I have lots of pics in my journal.
If the accumulator based aero produced superior results it would make your stance on accumulators appear misguided.
You do seem to do your level best to discourage their use, commercial growers only, floor space issues, explosions etc. If an accumulator/solenoid offers no benefits to using just a pump/timer why bother attempting to emulate the same performance using relief valves.
