You can kinda see how you will defoliate and then it grows back bushy again. Then more defol. You can see how the bottom of the plant is pretty clean before you will flip to 12/12. This will allow for good airflow when the buds need it! So you can also see how any branches that come off your 4 main branches can come up to the canopy. Any shoots that come off the mains that come out on the bottom of the main branches can be removed.
