Gotta have it.
If your using a ph meter or dissolved solids meter this is a must have. Not cheap but accurate. If you want your grow to turn out right you need accurate info on your water ph and fertilizer strength. Don’t think you can compromise here. Not cheap but reliable.

Not a quick shipper as promised
Do believe the shipping... it really does take that long. Packaged up soon after order but took week to actually get to carrier and shipped. Not a big deal. Why lie though?
P**I
Not what you get
I bought this product and never received ppm solution to cal. It I got the ph cal. Not the conductivity 1 tho messaged and never responded back what a joke
