He was asking me a question through a PM. My bad. Look here is how I feel about the whole darkness thing. If you havent tried it then bad on you. Whether or not if it does anything if you dont try different things then you wont learn anything. Try out a lot of different things that way the more you test, the better knowledge you will have on how you want YOUR bud to be. Its all about personal preference if you ask me. I have done the Darkness things before and after flowering and didnt really notice anything so I dont bother with it. But you wont know till you try yourself!
Peace and keep them ladies green!!
