not much stores sell digital PH pens and i need one still the only one i found that sells them sells 1 brand which is expensive think the store sells it for $120-140. online it costs $80. Wondering if it's worth it or just buy a cheap one?
my current grow is already in flowering so it will probably be too late to use it by the time i get it but i can use it on my next grow right after.
if so which would be a decent PH pen to buy thats reliable? also if anyone knows of a major store that might sell them please let me know i really don't see any stores here selling them. i have the test strips but i don't trust them to be super accurate
