Our third outdoor grow.

[Ithg]

If money isnt of concern, I suggest this oakton
Hand-held PH Meters And Oakton Acorn PH 5 And PH 6 PH Meters - ColeParmer-Canada Catalog

But if it is, just get a basic oakton, they're all water proof so no worrys.
Oakton PH Testrs And Oakton PHTestr Basic - ColeParmer-Canada Catalog
Its max range is from 1 - 15.0ph + cheap

Thanks bro, i like 2nd one :jointsmile:
