LST is Low Stress Training. it is when you tie the plants branches down to reduce stress from topping or FIMing. in LST no cutting is involved and the plants respond a lot quicker in my opinion. within hours of tieing down a branch, the furthest growth will respond by turning back up towards the light. if you keep leading the branch down as it grows, the lower nodes will eventually grow straight up towards the lights and will try and make a nice even canopy. you can eventually tie down what ever reaches a taller height then the majority of the canopy as well. with your situation it may be a little hard to find good spots to place hooks or other things that you can attach the string or what ever you use to tie down you plant. hope this helps. if you need a pic as example i can show you my closest LST try haha. keep up the work and get us some more pics!!
