i'm thinking i might just wanna get an electric ph meter too...theyre awesome and easy to use and i dont have to worry about running out of ph tester juice and shit
i'm concerned that if i buy all this and get a good growing system...how am i gonna know if the system is bummed out and sucks...i just think the roots suspended in water and spraying the roots with bubbles will eventually drown the roots...but then again I might just be paranoid
