Wow that does not leave much for your plant. Do you have a fan and filter hanging from the ceiling of the tent? What is the recommended clearance above the light and above the plant? The pot also takes up vertical space.
Given this height limitation you may have to bend your plant to the side so it grows out more than up. The net will help you do this.
This is one of the scrog frames I use. The first net (mason line) is 10" above the soil’s surface. The second net is 12" higher.
Here it is three weeks earlier. They are just starting to grow through the first net.
Here I am bending the branches so they grow to the side and toward a square that is empty
The stem top center of this photo shows how much I hand to bend it. The term is supercropping
