No bro no string here... lol.. All i do is pinch, pinch, bend...
Best time to do it is the day after you water, stems are softer,, if you havent tried it you should give a go.. Take hold of the branch between your index finger and thumb pinch until it gives a little, if we call that first pinch 6 and 12 on the clock face, then you need to do the same pinch at 3 and 9, it should be a bit floppy at this point and you should be able to bend it to where you want it, if it doesnt go there then pinch a little more... Its great for level canopy and spreading your plants as well...
Sorry if you know all that bro... But im sure some who read wont....
