My IIPA will crack concrete when it's done

Does that help?
No? Well, I don't see any way that the roots will try to get into your basement. They're more fiborous than woody and they're looking for nutrients, not stones. I don't think that you'll even need to guide them down with the cut off buckets. If by some freak chance they did invade your underground that would make a hell of a story and label for an IPA
