Thanks. Lemon juice is a lot cheaper than pH down!
Does it add any interesting taste to the smoke?
Where I live, the tap water is pH 7.7/EC0.7/ppm375 and leaves a lot of limescale in kettles and pots.
Should I aim to buy a few gallons of distilled or purified water just for filling the bucket during the flush, or does the stuff causing the high EC and ppms in the tap water not affect the plant when trying to flush out all of the chemicals at the end?
