Dude! What the fuck is wrong with you? I gave you all of the information you needed. I spent time using the thread search tool, something that you should learn to do, to find the post where Stink tells us what TDS meter he uses. Then I went to Google to find the conversion factor that that company uses. Remember
this post #8862? Didn't even get a +rep from you for doing that work. Didn't do it for one, but just pointing out that its sort of douche-y to not do so when someone goes out of their way to help you.
I did all of that because I got tired of seeing you re-bump this thread every 10 minutes asking the same thing after people politely tried to tell you how to go about doing it regardless of the meter and conversion factor. The absolute numbers don't fucking matter, it is all about relative to whatever starting point you choose and the particular strain you are running.
You then have the nerve to come back to this thread and rag on Stink after all he has done and after getting many good answers, to say that you "thought someone could answer." You then insult everyone else assuming that they aren't real growers if they don't convert their PPM back to which is rude on its surface and stupid underneath.
