A question from a fellow grower:
I do have a question, I have a hydro system in steel (4 Gal) I am having problems for pH creep. I add about a quart of H2O everyday and drop the pH down to 3.3 in the water I add to compensate for the drift up to 7.5. It is frustrating that I can’t keep the pH down at around 5.5 -6. I don’t have an external reservoir so I am adjusting this by hand.
