When I first tried growing Ak 47 AF Lowriders I was told to do a 20/4 light schedule throughout the grow. My first grow was ok on the yeild, but on my second attempt I increased the lighting and kept the same lighting schedule(20/4) and got a good size oz on one plant and just a little less on the other plant I was growing.
I am now doing a third AF grow with even more lighting (same schedule) and I am hoping to get even better results.
