what is the best ph# for the water to be.

[Treetops]

For hydro I like 5.6-6.0 and can't say I've ever had troubles at that ph. I personally think 6.5 is too high for hydro.

Cool chart Treetops!! :thumbsup:

Thanks Weedhound...Just so you are aware, the chart on the right is for dirt/soil..left side is hydro....
