When do you switch to flowering? I think that the reason you need to use two screens is that you are vegging until the screen is full. The point of the traditional SCRoG is so that the ONLY thing sticking through the screen is buds. To do that, the plants are usually put into flowering JUST as they hit the tip of the screen, so that the 'flower stretch' can be used to fill the screen. After that, it's only buds coming through.

I propose you call the method you are using D-SCRoG, for dual screen of green

I am interested to see how this grow turns out with your dscrog
