Hi Guys. Do any of you use a CF meter for measuring the strength of the nutrients in your water? I know these are used for hydro grows, but I want to know if its a requirement for soil as well?
Yeah, we need a good soil testing section. I have a couple crappy soil pH testers, but what about EC? I thought that was just for hydro, now I am seeing it tested in soil too. Also, will 1 tester test for pH in both soil and water? Do you have to drain the water through the soil and test only the water? So many questions, so few specific answers.
