i know a bit about hemp.
it is grow really differently than weed
the main difference is that you plant them really close together. so that the plants compete for light and grow nice and tall. Thus creating more fiber.
I dont think they are ruteralis, because all rutes. are just wilde russian strains and are reletivly recent additons. Hemp on the other hand has been bread for thousands of years, and it is a Sativa (70% sure)
the only difference is that hemp strains, as they are the same plant, are bread for the fiber and low THC content.
I also dont think it has significant amounts of any cannabinoid. as several CBD for example is created as THC breaks down.
But i'm really not sure
