So I've been pondering about drain to waste systems, wich can give perfect nominal pH and nutrient EC. I can't stand the thought though of the "waste" part though. I would feel like a bad person, litterally, throwing all those extra nutrients away. Not that it's especially much more than when doing regular swaps of whole tanks in recirculating systems. and just our daily piss, probably is much more each day than what's wasted in our hydroponical systems. But you just don't do that!
Anyway, if I'd do a run to waste system, saving all the "waste" to a tank, wich I'd then refurbish by heating to almost boiling point(97-98C), keeping it there for a while. It would then close to sterilised. I'd then top it off with new extra nutrients up to the correct EC, then start using it in the system. Could do this pretty easy since I already got the "tank" with heating from a no more used make-moonshine-set-up.
Anyone know if we'd have any problems with this refurbished nutrient solution? I don't find much on this googleing. The sterilization/killing germs part must surely be enough(I could add some bleach or h2o2 if heat is not enough)?
But will the heat break down any nutrients or do something else? I understand the proportions between nutrients will be another than what was started with, but I'll gamble it'll be sufficient, and when mixed with new nutes according to recepie, guessing it'll be at least better than most of times/generally in re-circulating systems.
It would feel good never wasting any nutrients, always reusing that last part, and at the same time probably have a better "Nute-In" value than in most recirculating systems.
If it works as I hope, you'd minimalized your waste. If working the heating/pasteurization
