Here is a great tip for those who use reverse osmosis water to buffer your water and help stabilize pH. There are two ways, both efficient.

- For those who prefer simplicity, all you have to do is add 20% tap water to your reverse osmosis water.

- For the purists who do not want to use tap water, or whose water is particularly bad, here are two easy steps:

1 – First increase your pH up to 10.0 with pH Up or potassium carbonate
2 – Then bring it down to 6.0 with pH Down

In both cases you’ll obtain water well adapted to hydroponic nutritive solutions, while avoiding untimely pH fluctuations.
