does anybody recommend any cheap ones?
Worried about ph drift whilst im away so would be nice to know there's something reliable for just a week.
Also, does RO water with nutes have much drift? Ive found with ph down in nutrient mix with hard water makes my ph actually end up HIGHER than if I don't use it. Unfortunately my mix without ph down is still too high.
Thank you
