So i decided to run a small experiment where i grew 3 plants in coco. one with distilled water the second with bottle water (soft) and the third with well water (hard) .
i noticed that the runoff PH of the distilled water one was rock stable through out the grow and that the harder a water gets the harder the runoff ph drifts .
propably is a known fact but i noticed it and thought to share it
i was really impressed with how stable was the ph through out the grow . i also instead of flushing decided to water with just distilled water till the runoff shows me 12-20 , without phing the solution. just pure distilled water and the ph was rock solid till the very end
