I have been defoliating since just before going to flowering cycle and I have done so twice since then and by allowing the light to hit all the bud sights they have developed great budding growth. I am using a 2'x2'x4' grow cabinet and they are under a 600w HPS HID/they were veg'd for a longer period under a 600w MH HID lamp. This is my first grow in this unit and I could really use the learning experience from what you have to share, I am inexperienced at defoliation for this purpose. With what you can teach us I feel that it would help me dial in the defoliation process in order to increase both yield and potency. I want to learn how to do it better and dial it in, thanks' for your post and I would appreciate learning from you.
