Doesn't really matter which way you do the Scrog, horizontal, vertical, up-side down , you will still have to train the plants to grow into the screen. Plants want to grow vertically, yes, but they also want to grow outwards. Therefore you will have to train the growth from the opposite side of the plant where the screen is to make this effective.

Personally, I don't think you can get the full potential out of vertical scrog with the T5's. The benefit of vertical scrogs really comes with HID's, because you are able to use 360 degrees of the light. For example:

1000w HID has a footprint of about 5ft x 5ft, and is usually kept 24in. to 36in. from the tops. That gives you 25 sq. ft. of lit space.

Now, turn it vertically, hung about 3 feet off the ground, with chicken wire wrapped around it, 36" away. Now, the surface area of your lit space is: 5ft (height) x 3ft x 2 x pi (circumference of the scrog), which now gives you about 90 sq. ft. of lit area.

There are many examples of them all around the different cannabis forums, so I wouldn't really call it an 'uncharted' territory. I haven't looked into them so much, but from what I have seen, it's always HID. Maybe you can find someone who has used T5s, and if so, send me the link .

It sounds like a nice project, but if you're only using T5s, maybe you can do a side-by-side vertical and horizontal and see how that goes.

Happy growing :jointsmile:
