i was merely pointing out how "an expert" uses a natural lighting schedule to increase your chances of getting females...did not mention a word about soil! just because Jorge's book mentioned soil you can't apply his lighting method? how many growing books have you published with millions of copies sold? i am not an expert and will never claim to be but his method is common sense...no where on earth does 24 hour light exist except in the polar regions so by using a more natural light schedule increases your percentages of females to males...when i used this method i regularly got 80% girls and rarely got any herms! keep doing things the way you like but i know many who have switched to this method with a high rate of success! :jointsmile:
