I am on my 2nd grow and didn’t even learn how important pH is until the middle of my 1st grow. I believe that lack of knowledge had a big impact on my small yield.
Fast forward to yesterday when someone here, @Mark047, explained some about TDS PPM and how testing that stuff is AS important as pH testing.
So I googled it and my search results included a single result for anything gardening related, and this was that article.
It sure was easy to grasp and taught me quite a bit.
Now I just have to find that pesky meter and figure out what its Conversion Factor is and what the level of PPM/TDS for Marijuana is and I’m ready to test that shit ASAP.
I hope this will benefit some of you too.
