If he can't prove it NOT helping, then how can he say it doesn't help? He's making claims here, not me... so the burden of proof is on him.
I repeat: The claim that RO is required for growing cannabis in hydroponics is extraordinary. The burden of proof of an extraordinary claim lies with the claimant. So- how did you determine that RO is necessary? Specifically, what problem were you seeking to resolve- and did it work?
And what was that 'scientific sounding mumbo jumbo' you were accusing me of a few posts back?
You're at very high risk of being deemed a troll at this point. Knock it off, begone or I'll see to it that you are gone. Remember, I am a mod now, albeit a somewhat reluctant one.
I agree my hydro shop has everything in 250g bags, small bottles etc, cant get bulk. How did you convince them to get 20L H2O2 in?
Oh, they can get bulk packaging if they want to. However, if you guessed that the margin is higher on small packages, your guess is right. Ask them for larger packages. If they won't respond to your requests for larger size packages with appropriate discounting, shop elsewhere. My hydro supplier was quite happy to buy in 25kg jugs of H2O2, particularly after I did the shopping for them, obtained pallet-quantity pricing and indicated what I would be willing to pay, which included a healthy profit for the shop.
