To calibrate your pen you will have to buy the calibration soluition,4.01 & 7.01.You cant use your nutr solution to calibrate with.On the pen there's two trim screws,one for the low ph 4.01 and one for the high 7.01.You put the pen in the 4.01 solution and turn the screw and the same with the 7.01 sloution.Now it's calibrated.You will do this about one time a month ,just so the pen will give you the right PH reading.To have a early and late crop just start one and 5 weeks later start the second. Best of luck to you. PEACE
I'm going to add some nutrients ASAP! But still for some reason, I don't think that the water is reaching the roots when using the drip ring. Do you know a website that sells the pH solution? I know that I could look for it on a search engine, but I'm trying to find out what is recommended by the users. When I mean early and late crop, I want to harvest 10 clones around every 30 days, because I like to smoke more than the average. I was thinking about a Flood and Drain or some type of Aeroponics system to use. Thanks for all of your help!
