Here I go again

[M4ur]

Yes… I just got a storage solution (20ml for 2$ but I suggest you to grab a big bottle of that solution, is 10-12$).also you need ph buffer 7.0 or 4.0 to calibrate the meter… Everything will be around 20$ beside the meter.
PH is the vital component when you grow mj plants… So, if you want healthy plants you need those. Is just my opinion, againe
Read this thread please

Lets talk about PH Meters

When you purchase a PH pen, a TDS, or EC meter; You always store the probe in storage solution, distilled or ph buffer 7.01 solution. Never store dry. On another note. Probes go bad anywhere from 8 months to 2+ years depending on use and storage. If you buy Milwaukee or Hanna meters; You can buy replacement probes.
