That shit looks sick Boomer. Nice setup, I had dreamed of doing more and my idea looked a lot like your room, but I am very limited on space right now. I liked your old sig pic better. As far as the meters, I grabbed them because I was sick of waiting for the readings ever day, but the give very different readings on my nutrients than the old meters. I calibrated both the old and new, and the old was reading what it always read(calibrated normal)but the new leave in one was showing the ph .4 higher than the old meter, and the ppm 250 higher than the old one. I checked both new leave ins and they had the same readings, but the old ones were still completely off. So Im kinda trusting the old ones since they did me right in the past, and I wating to see if I want to recalibrate the new ones to the old ones or go with the new readings. Otherwise the probes seem of decent quality, the lcd is backlit but very dim, so Im not to worried about it. The blue lab meter is a green backlight and the hanna is kind of orange, so that is in a better spectrum, I give a btter report when Im not so high and I have a little more experience with them.
