noob-friendly is key imo. I'm still green with hydro and Ebb and Flow's larger margin of error has saved my ass many times already. I love my aeroponic cloner but I left the pump off on accident for a few hours and lost two clones... it also doesn't have anything in it but Clonex and water though so no nasties build up in it. I would probably fuck up DWC somehow too, and it also makes me think of pythium...
Clonex is not a pathogen inhibitor. Left long enough (long enough for the chlorine in the tap water to flash off, a few days), pythium & fusarium would colonise your aerocloner soln, no freaking doubt. Regular application of H2O2 is the trick to keep it all clean, aerocloner or DWC.
Might be a good deal, but whatever you do, don't fall prey to the pseudoscience claims made by some new-age nongs about drinking H2O2, some which appear to be linked to the cited website.
For the uninitiated, there's some truly nutty 'alternative health' loopbags out there who think that it's a good idea to 'get more O2 into the human body' by drinking H2O2 (as if your gut were made out of lungs or something). I can't think of a worse idea. H2O2 is great for sterilising your hydro op tanks, but somewhere between ineffective and stupid for human ingestion. All that is meant by the 'food grade' classification is that 35% H2O2 is suitable for decontaminating foodservice equipment. It DOESN'T mean that the stuff is suitable for human consumption.
