Treez, my most recent scrog had plants that were 8" from the top of the grodan cube to the screen then 6" to 8" from the screen to the light so yes the total plant hieght was indeed 14" to 16". (picture a flat space of 24"x24" of nothing but 6" to 8" tall buds) The T5HO light fixture was less than 3" total hieght. If I had been using the "drain-to-waste" method of watering then adding in the 6" for the grodan cube brings the total hieght for everything together would be literally 25". Even adding in another 2" gap between the top of the plants and the light it would be only 27".
Real life being what it is the absolute minimum numbers are rarely achievable but you can see that 35" is entirely possible even if you have the growing medium or container pot at 12" rather than just the 6" for the grodan cube.
One reason scrog allows you to use low vertical hieght dimensions is that in a non-scrog system when plants are 30" to 40" tall I have found that the bottom half of each plant is essentially non-productive so that space is wasted. The only "wasted" hieght with scrog is the distance from the medium to the screen. (8" in my case) The most important reason for scrogging is the increase in production per square foot of floor space and even production per cubic foot in your grow setup due to the light being equally available to all the buds not just some of them. Also when using T5HO the light penetration depth is not even close to that of HID lighting. But as you and I know T5HO rocks for other reasons including being dramatically closer to the plants.
Give it a try a couple of times and you will be throwing rocks at other methods. It is even possible to shorten the hieght further with some advanced planning but that is for those that are very experienced with not only the method but their individual strain.
Did I miss anything Scrogbox? ;)
