In a 22inch tall, 11 inches wide, and 6 inches deep box, what would be an average yield? One plant. Other factors include under a cfl and i was thinking about auto flowering strains because they generally grow small and this is only a 6 inch depth box. Considering the light and container holding her is taking off a few inches off that space. Given that people can do it in a computer and this is alittle taller than youre average desk top how much yield are we looking on at average and or at best of one plant?
