Catastrophe scrog..I don't think so..lol. Ya completed an attempt. That's more than some.
Scrogging out a large plant or any plant in a small area is a lot of work. From what I saw all you were missing was the timing. Plant count under the screen is super import as well. Clones are excellent for scrogs because ya mainly know how the plant will grow. That advantage can be taken away if you throw to many plants under a screen. 1 or 2 clones will fill a 4x4 with ease and allow you and the plant more room to grow and work on it.
This multi grow I have going I threw a screen and 4 plants in a 4x4. I've since had some health issues and just can't manage a scrog this round so I removed it. But in hindsight I think that was a good move. I know what an overgrown scrog looks like and it's not a fun ride. Ya end up removing a lot of material that was intended to be a part of your scrog. That's not how it goes..lol
A guy with your skill set would rock a good planned scrog. If ya try it again feel free to bounce any questions off of me. I learned to grow using a scrog. I grew my first plant normal. After that an old Australian grower showed me his scrog. I never looked back.
Someday id like to gather all the info and hands on experience I have with this method and make a nice sticky thread.
