Hello ,and a Happy Easter to you all. I would like to tell you of my last couple oF days and the interesting thing that I have found out. I have been using a Oakton Ph Tester for the last 8 years or so and untill the last two days the pen has been perfect. So 10 days ago I strart some new seeds (Bogbubble, Lifesaver and some Mystery BOG strains for a total of 16 seeds. Any ways after all is said and done I have 6 BB, 2 LS, and 2 MB. I go to set up my bubbler under my flouresents, put the stones in the H2O and go to test the H2O and my pen will not stay at one point on the ph scale, it just jumps all over the place. So I re calibrate the ph pen and try again, same thing. So I take the pen out of my grow room and go to another part of my place for new H2O. I test the H2O and the ph act's like it normaly does.... so I think that's weird...what's going on? So I start by testing everything from new air stones, and container's to changing the air pump, but everytime I go near my grow room and the cloning/seeding area the pen freak's out....! So I finally figured out that the pen seems to be affected by the flouresents. So for all out there who have this type of pen... BE CAREFUL my pen seems to be affected by flouresents, so FYI.Anybody else have this happen?;)
