I would like to recommend a product that I been using this entire grow, its called Mad Farmer's Silica Shield. Here is why, today my good friend came over and accidentally knock my bathroom towel rack with towels right on top of the Cougar. There were 4 branches that were bent completely over and not one branch snapped or broke. The branches look like nothing at all happened to them. Close call and almost a early harvest. I will say this about all my plants this grow, their stalks, branches, stems seem very strong and hard. I am sure the Silica Shield played a major role in that. I'm going to buy for every grow now.
Peace
