Hey gang just thought I would drop you a line to let you know how things are going. Got in a hurry and tried to run unit without a PH tester couldn't find one in my area so I had to order on line. Well I thought I had a good idea of how much nutes to add and had it deluted to a minimal amount boy was I wrong only planted 2 seeds so when I burnt up the seeds it wasn't a huge loss but still a loss. I know have my tester and when I checked the level it almost turned dark green OOPs well know I have it regulated pretty good and have all the stuff to keep it constant. Will get back with you later to let you know how it is going thanks to all for all the help GREAT SITE and burn one for me Your Bro the old hippy DUGOUT
