No this is not a bad idea it is a bad way to do it. What you are doing is called low stress training and many growers do it but not with tape. Use plant wire which is basically a spool of wire coted in plastic kinda like a bread tie that you cut to the desired length. You can pick this stuff up at just about any hardware store. Tie the wire around the plant and then tape the wire to the bucket. Or you can top your plant if you wish to create more growth. Toping is when you cut the tops off of your plant, when it regrows it will shoot two new tops from the cut area. There is many good videos on YouTube that will explain all of this much better just search LST cannabis or topping cannabis and a ton of videos will pop up explaining these growing techniques.
