LST or scrog?

Last and the trellis is pretty close to that same thing. The only real difference is what you're trying to attach too. It pretty hard to screw up the plant with lst. My first grow I wished I let it grow naturally. That way I could have first hand comparison to what the plant wants to do vs what I want it to do. Then I can see each grow if what I'm doing is actually increasing yeild or not.

Newbie to newbie im gonna try both, lst and a trellis later on, im not gonna go full scrog, straight away but hopefully im gonna need a net to hold up those big colas Good luck

I would recommend LST first. Scrog is fun but can be a pain. You can't take plants out to look at them in scrog.

They are usually complementary techniques, but if it's your first time I would avoid the SCROG net simply because once it's installed you can't move the plants or take them out of the tent, which makes it a bit more cumbersome to work with the plants in a fixed position. However, it's all about experimenting. Good luck!
