Wow Thanks everyone for chiming in. I'm not about to get into an argument over which methods work best and try to blanket statement anything but I'd say the the posts in this thread show how much variance everyone uses to find what works for them. I use glr to veg and can't imagine anything causing tighter node spacing. I would say that using glr on Indy dom plants have see them mature and even preflower. For satys that could be an advantage to plants that tend to veg out of control. Same way the longer times might be beneficial for someone needing taller plants with stretch and longer distance between nodes.
