To make the grow tubes, I cut slots across with a hack saw and then heated the plastic with a heat gun to soften it. Once it was soft I pushed in a tapered wooden plug to hold it open until the plastic hardened again. I did this outside because the PVC gives off some fumes when you heat it. The second photo below shows a close up of one of the openings after the tube was filled with pea gravel.
