Treetops Reviewed by Treetops on . where can i get a not so expensive EC/TDS tester? Ive been looking around and trying to find one that isnt $100+. Im just doing a small 1 plant W/F grow so do I even need one that bad? I see stuff in here that indicates just following instructions for the GH 3 part or Latewood's recipe with R/O water, calmag+ and LK and it should be fine. Then I see others expressing the dire necessity for a ec/tds/ppm meter. This is my first hydro set up so theres a huge learning curve that im trying to accomplish without asking too many questions.
