Hey chromophore,
Looking great! Gonna be some lg ladies! Ill follow along looks like a great grow!

One idea, someone said earlier, is tying your girls down. I think you will have great results tying them down without a screen. What I've learned, from doing it, is your going to want to train your plants for a scrog from the start. If you do the screen with your plants you will end up blocking way more light to way more bud sites than if they were simply tied down to open them up. As they stretch you can tie them more ( keeping it a little more open for light penetration) then if you pack the screen above full of the stretching plants.

My 2 cents
If you do scrog, it will still be very interesting to watch, looks like you're off to a super start!
