One of the plants filled out like a normal plant, but one of them was kind of airy and this is what i find to be the biggest problem amongst autoflower's the fast that they do not fill in like a normal plant would. No matter the environment they never seem to get super dense. Must be in the genetics. The only one that did not exhibit this trait was the iranian, it got so dense and so big I got bud mold on the inside of the bud where the stem and node touch the bud. This was outside though and had no problems with bud mold indoors.
