Homemade. alwaysba dilemma with which qatly to try bit each grow space is different so difficult to generalise. for yield with no restrictions on time , we have many options , with autos its a  whole new game .lpl i am currently trying different methods in my perpetual auto grow with lots of different strains too. decisions on the way to try eachbjnenhave been based on their general grow choice that I then try to coerce into a form of training. As we don't have a recovery time to enjoy using , we have to be quicker reacting with no damage to slow growth.  inhave tried topping,  fimking , quadlining and my own recent quad +1 version . Fornmy room i cannot go too high due to apex roof so need a squatter plant than a natural grown one would give. By using the quadline I am able to create a more even canopy with longer stacked colas.  Once the initial shape is set , the lower nodes of each branch are stripped out too. this concentrateds all that energy to the mains we chose  No popcorn or bushy , light swallowing mush that wsdtes lumens for us. I adapted it by not removing the 5th nodes and instead pulled them 90° horizontal until the lowers have caught up. this gives 5 huge colas To get the long donkey dicks.  easier for airflow management too.  topping the 5thbisba good method too but I hate losing such a vigorous growing tip now so at a push i fim but never waste it usually.
