"Hemp" maybe considered an invasive species, because it isn't "native" to N.A. It was intriduced as a cash crop shortly after the europians settled in the americas, and later became feral.
Plants that are properly cared for, have both root space and plenty of room for vegetative growth will produce not only much more product, but it will be better quality. "Drug" quality cannabis needs the proper nutrients and care in order to thrive.
I'm going to go out on a limb here, so to speak, and say that out of those 11 plants, 3 will survive and produce more than a thimble full of smokeable product. "IF" you leave them all in that pot. They will be in competition for sun, nutes, space...everything. They won't do well, believe me.
Those folks growing plants in 'pill bottles' do it as a novelty. Nobody I know or have seen does it for the product.
