No. lol My apera makes a smaller hole than my bluelab but it doesn't take as deep a reading (doesn't seem to matter for me at least). It doesn't really bother them, at least I haven't had issues. I suppose poking holes with a contaminated probe could cause infection. Really though that little root pruning has never stressed my plants or caused issues.You found a ph meter that actual works for soil with out a monster hole?
