woot woot the flowers are stating to come in and wow what a differnce the new ACCURATE ph meter made, was something I wanted for a while but didnt make the purchase. My old $50 meter was off by .27 even right after calibration!!!!! I can only imagine how much it drifted after a week or two, very happy with the $120 tester, I reads almost instantly and is very precise. I started co2 this week and switched to flower nutes.
