THE GROWTH: 4/5. Starts off a little slow and seems to be extremely sensitive to light early on. I had to keep moving them away from my lights for awhile. Once they get well into flower though, the light sensitivity goes away, and they get some insanely long legs underneath them. They get extremely tall and will begin falling over, so be prepared to support them. Of the 5 Meph strains in my tent this grow, these got the tallest for sure.
