Yeah, that is a combination of different training techniques. While it can be very beneficial to the yield, I dont like just growing one single plant. I love the variety growing offers. I have day time smoke, afternoon smoke, and knock me out night time smoke. I grow combinations of sativas and indicas, fems and regs, etc. I generally go with 4 at a time but ended up with 2 of 3 males of one strain when I was hoping for 2 of 3 females.
