Cheers mate, just read the thread, interesting theory you have. Seems my dragons are only a few days behind your grow so be interesting to see how things go on. At the moment I don't have any nutes as they are all over at my good friend Grey Donkeys place (we have a shared indoor grow going on there) most of what I had was organic however and it would seem that's not best suited for airpots. What nutes are you using for this run, in know you said mineral but what NPK are they.
