A - how high is your net from the floor?
B - how long does it take before you flip to "fill a net"?
I think that if you look at your total grow time and how often you harvest per year you'll see why I chose to perform without a net
I just flipped four 4-top plants, one was 43 days and the others 52.
What I save by being able to flip as early as a month and a half - and having room for more small plants - and being able to rotate plants through my flower room - gets me about a harvest per month or so - and a variety of strains instead of a ginormous harvest of one strain that takes forever. So far this year I have harvested 5 separate grows (11 plants), getting from 2-5oz each plant.
I think even if I went for a longer veg, it would still be a manifold, just more limbs and a bigger pot.
Oh, stoner dude forgot...
The A and B questions are about the stretch. You may be tucking sideways, but if you weren't you would be vegging 3'-4' tall plants. Some strains stretch almost 200% after flip. Most I have grown are 100% or less, but 100% puts you at about 7' total. It's stoner math, but I think the long veg and strain are your stretch issue, not lights.
So if you are set on a scrog, I would use a smaller pot, or at least a wider one to shorten it, and lower the net so you don't have to veg as long because you can start tucking sooner.
Oh, and if you use twist ties instead of tucking you can reposition stuff if needed, like if some limbs outgrow others. get them through the net then tie everything down.
