I think timing is critical in a scrog.Ideally you want the plants to do alot of the stretching out of the screen so they are building bud sites.The best way to do this is figure in your rate of growth,And how long you think it will take the plants to Fill the screen.You know its gonna take them a week before they even start to flower and than you have 3 weeks of stretching after lights out to 12/12.Figure in the next week if you flip now them filling everything else in and also be prepared to cut shit so your tops arent all over top of each other.I think you can get away with a branch in every hole if you do some defoliating but dont get crazy with it.There are alot of mixed reviews on it and i personally dont like to remove to much cause the plants get there energy from the leaves not the buds.Ill start removing more and more towards the end to really fatten the buds and ripen them but not while the plants stretching.Just remove the leaves that are absolutely necessary.I think your grow is gonna turn out real nice.I like your scrog,It looks good.
