Desperate help needed ppm

Discussion in 'Growing Marijuana Indoors' started by crapskater, May 3, 2006.

  1. I just purchased a ppm meter not knowing that it ranges from 0-999. I know that ppm for hydroponics will be >1300. Is there any way i can measure that much with this meter by mixing two solutions? or is it just a waste of money...
  2. are you sure it's not 0-1999? Most I've seen go at least that high. I have a 3-in-1 (Ph/EC/TDS) tester that goes to 4000ppm and it wasn't more than $180 - so unless you got a really cheap one, I'd be surprised if it didn't go higher than 999
