Couple per plant and the rest are just tied to themselves
I don't think I need anything more than some general support. I'm thinking a plain ol' 4x8 trellis that spans the tent. One lower to direct the stalks and another up high for fat nugget support.
When I first started out, I was sold on a scrog net, but I was terrified of root rot, so I ran 1 big plant a couple times. I ditched the scrog method when I went to 4 plant-sites because I assumed 1 plant would inevitably get root rot and need to be removed. Never had rot but I like the style I've grown into. I'm sold on the BIG FAT NUGGETS but they've proven time and time again to be too heavy to support themselves.
