First time scrog how's it look?

What @00110001001001111O said and I think that net could be moved down a bit.. carefully. I would also check those roots.. Good luck ✌️ 💚

They can be used for training or suport.. or both. if one is taller you can use it to train it out horizontally until the other catches up. Depends on your plans for the canopy a bit, too. Looks like you aready did that a bit, but those branches will turn upward just past whatever is holding it down, so some of that height is coming back within 24 hours. I don't think it's too far down.. it's right where it needs to be to control one and allow the other to even out. Scrogs are great. Wish i started using one when i started. Takes a few consistent grows to work out a well-thought out plan. I think they help visualize stretch too. I usually have 2 "squares" of 5" LxW each between plants when flower starts and confident it'll fill in those gaps before vege growth tapers off. That may not be universal (different size of plants at flip will have different stretch and any number of other relevant factors involved), but the concept translates - gain familiarity quickly. I use one for traning, then 15-16"above that a 2nd scrog is for support in case of weak limbs that can't hold their weight. Happens occasionally.
