Hello there. Hope I can be of sum help. It really depends on how many problems you encounter though your grow. In all actuality when you do 12/12 the plants still go through a 2-3 week veg. The only difference between going straight into 12/12 is that you don't have to switch the lights. Yeild depends on thte genetics inside the seed. You could get from as little as 14g's - 2oz's.when growing I allways like to say ya never know until you try. Going 12/12 will allow you to have more plants in at a time also. They will not get as big as if you were vegging them out for 7 weeks or so. I do believe if you try you will amaze yourself. I promise. Whatever you do. Keepm Grow'n
