I have been going through the same ring around the rosie routine with someone else in another thread on the same topic and I am more than fed up with attempting to educate the ignorant.
I suggest that you do what I have done and that is get roughly 37 years of growing experience under your belt and experiment with virtually everything imaginable, exchange information with other growers for decades and also exchange information with people you run across on pot growing websites, and I would suggest that you become a member of several more of them so you can have access to more experienced growers than most members here have proven themselves to be, and read things like Jorge Cervantes grow bible and numerous other publications of expert growers and if possible like me you can be an owner of a nursery that covers roughly 12 to 14 acres and who has four family members with degrees in horticulture who like I have you can ask any and every imaginable question about growing and lighting and then after you have done all that get back to me and then tell me that I am wrong.
Until you have done all that there is no need to address me on the subject again because I will not waste anymore time responding to people who are either ignorant or pigheaded or both.
When someone new asks the same question again, which seems to happen almost ever day or every other day here I will tell them the facts one time and leave it at that. If you or anyone else wishes to argue about it you will have to find someone else to do it with because that is not why I am here.
