So with NFTG they recommend your medium be no more than 400 ppm and run off I believe around 6-7 pH.
I do not have a PPM meter and was wondering if anyone has done a roots original slurry to check the ppm?
They also state when in doubt flush with Herculean harvest or pH up. How much Herculean do I use to flush and do I go until I have a shit ton of run off?
Thanks for the input!
