just got this ph pen, does this pen look aight or should I get a new one? this one was free soooo...Im indifferent, as to whether or not if I have to get a new one.
I have the same one, and I have no prolbems, I have had 3 great grows with it. If your a new grower this ph meter should do you justice for a nice amount of time. So yes its a decent Ph meter. Good luck Yay my first post.
