I was going to consider lst as my first go to but right now there is no room for me to do so sadly. I have 2 autoflowers growing in the green house with it and its pretty tight in there lol. The 2 autos should be done and ready to harvest in a week or 2 so might wait and do the lst when she is the only plant in there
Have you ever tried any "super cropping" bro? or looked into it at all?
Ive only started doing it accidentally when I would accidentally bump into a branch enough to bend it over but not break it, Then a day or two later its back up and grows a knuckle that makes the stem even stronger. They will stand back up but if you do it two or three times and also do one or two tie downs in a spot, you can basically make an "
S " out of the stem and tie off at each curve.
Wont require as much space as full LST, and will make your stem stronger, and will cut down on like 4-6+ inches without having to cut any of your nodes off this late. The one thing I would be careful of is during flower when the stems harden up they will not be as pliable as they were in VEG and new growers (not sure how long you've been growing) usually dont have a feel for it and can easily snap stems because they are used to being able to bend them so much... You still have time for that, but its something to be aware of.
Do your research first if you decide to go this route... It can seem brutal and you probably wont want to take the chance of doing it because it seems so drastic to basically bend your branch in half, and looks like you've fucked it up, but they pop back up relatively soon and like I was saying those knuckles actually help a lot for stem strength/stability.
