The One Shot Bucket System....

What should the pH be set at? And you normally adjust the pH with vinegar and baking soda right?

Propher Ph up and down work better. Lemon juice, vinegar, baking soda all work but they don't last as long and will build up in no time at all.

You want to keep your Ph between 5.2-6.0 at all times.
As the plants use up nutrients and deposit others back into the water the Ph will change and should be adjusted twice a day to maintain proper levels.

Twice a day?! And why does hardon recomend 6.8pH? Is that for soil growing?

Correct.

Soil grow requires less acidic / more alkaline environment than hydro or bucket grows.
