Don't know your training style. I use two things. I have a bunch of these adustable plastic clips. They work great!I also use a tie down set up. It consists of 3 items. Garden velcro tape, soft wire and clam style paper clips. Take your tape and wrap it around the wire. Move the wrapped tape down the soft wire far enough that you can twist the end back on itself tightly so it can't unravel. Make the tape as long as needed, make a hook on one end for the plant or loosely loop it around the branch and twist the wire on itself for stronger pulls. Just clip the velcro tape to the top edge of the EB.
It's easy, flexible and resuseable. It's not too much of a PIA with the cover if you build the nute mound large enough for limited top dressings needed.
I try to use the clips as much as possible and they work very well.
