I think they are too thin because I'm not getting much sun these days from a window. I also think autos are great for window growing but you need to start way ahead around like a spring.
@Tonino, I still get some of the days pretty decent lighting, but through the night its temperature on my balcony around 5 degrees and that's bad. So I keeping them inside close to a window, but I can't switch those just feminized in these conditions, because of too much light...
