Hi – looks like your clip method is working for you. I usually veg with floros too and what I like to do – I grow in rectangular earth boxes – is to wrap a bungie around the box just below the lip and then use those furry pipe cleaners to secure them to the bungies. I just do this until they surround the box and then flower them.
But I might recommend using the led to veg. I am doing my first led grow with a 400w solar storm and I’ve found that the nodes are almost too tight lst like usual. I feel like I’m getting way more bud sites for same height.
