Hello, You may fair better using mainlining rather than LST. I feel LST requires that little extra veg, for all the training that has to go on with recovery as well to be taken into account. I top and mainline in a 60x60. Usually have between 6-10 top colas. I find this easier in my small space as I can lower each branch down and use topping to allow the branches to make an even canopy. I really don't have the space to do LST properly or how I would like. I hope this helps, good luck and happy growing
