Review on Accurate Hydroponic Growing: General Hydroponics 4 01 Calibration Solution by James Vilchez

I haven't used the product yet, but I've started scribbling the expiration date with a marker, or at least I think so? What worries me is that they even decided to trick the customer or make him wonder if it's them or not. Shady if you ask me. Now I have to deal with the expiration date before I even break the seal. I will update the review after a few uses and weeks after opening. But for now 2 stars!
