Indoors they can get huge in the right conditions especially of you keep pouring the N to them. If you think about it aren't they vegging and flowering at the same time during a big part of their life. If you keep up pouring the light and feeding them I dont think they ever really stop stretching.

The Great Pipeman & Marlboro Auto Grow was my first time really trying to grow an auto and first grow in the RDWC. I kept feeding them N until the 7th or 8th week I think and I had to super crop the Pineapple Express and the Gorilla Glue 3 times to keep them out of the HID's. The smoke was good on all of them, but they were all different phonotypes from the same breeders and you cant clone them for the way I want to grow. I did hear a rumor that Autos Suck and whats his name didnt kill himself in that cell..
