The wooden structure I've posted some pictures of that I use for strains I know can get huge helps a lot for me; I can do 10 and 15 foot pants because the wood is in a mesh design, so it adds support to branches and I just cut off whatever branches start getting to close, and I can do them tall, but that is also because I have woods behind that, so you can't really see them back there. I did learn this passed year that at least with Blue Cheese, a couple small clones can produce almost the same as a giant; I waited until my seedlings were bigger before cutting clones off, so by the time they were ready they weren't very tall at all; barely chest high and that includes like a foot or so of pot, which means they'd be like belly button height but still produced very well, so I'm thinking that this year, I'm gonna utilize that wooden structure for the taller ones, and then the smaller plants can be outside of that.
I've got Grand Daddy Purple now and I'm gonna place that either near the structure, or in the greenhouse so that I've got something I can tie up branches with as I've heard that strain produces really large buds.

There's a few more strains I'm deciding on but those are for sure going in and around the structure.
