That’s an awesome sight mate, love seeing plants like that.
I am growing in a 4x8 and found the same problems with 5 plants in there. That led to my current grow plans and setup. 18 - 15” square fabric pots, each plant gets mainlined, 2 cuts giving 4 tops.
The pots are heavy wire framed with 2 handles that are made so that the corners, of the handles, make an 8” square. In my tent that will give me 72 tops. Above the pots, height can be varied, sits 1/4 steel rod supported by an aluminum rail between the tent posts. These rods are spaces 8” apart and give me a place to tie and support each top and giving an even spacing of 8” and keeps the canopy nice and even.
Always heated the idea of nets and this lead to my current plan.
