I am a beginner at growing. I've done plenty of research on how to grow. I feel like I'm looking to indepth about how to use/maintain my PH600 meter. I just bought a PH 600 meter. I know I need storage solution and cleaning solution but with the PH 7.0 Buffer Solution should I buy 25 20ml packets? Also can I reuse the 20ml packets for each use? Can I use one packet 3-4 days twice a day? Do I need to calibrate it in 7.0 solution each time? With the storage solution should I just put some on a paper towel and place it in the cap to keep the electrode moist? Thanks in advanced!
Also I would like to add that I am growing out of a AG with 1 auto ak47. Once all my supplies gets here I will start a journal.
