About the Meters & Tools category

In this guide you will find Information and links to PH, EC,& TDS, meters, pens & solutions offered by our Official Sponsors and Vendors.

Just got a TDS meter and got a reading of 756 ppm from my run-off. Is there a scale that gives acceptable ranges for run-off ppm?

Hi Latewood, I have some questions about EC and the grow information on the grow, Booster and THC pack sold on this site. Is this the correct category to put them in ?.

Take care.


sorry I posted in wrong place.
