10. Hemp
Don’t worry it’s legal and very profitable to grow hemp. Difference between marijuana and hemp is quite significant but many people mistake them. Both belong to the same plant species, Cannabis sativa L. but by definition, industrial hemp is high in fiber and low in THC (tetrahydrocannabiol) which is the psychoactive ingredient of marijuana. For example, the European Union strictly regulates THC levels of industrial hemp requiring it to be less than 0,3% whereas levels of THC in marijuana range from 3 to 30%. One acre of hemp can yield around 700 pounds of grain (which can be turned into 22 gallons of oil) or 5,300 pounds of straw which can be turned into fiber. Five gallon bucket of hemp oil costs around $150 and potential returns for hemp fiber range from $170 (low yield) to $759 (high yield) per acre.
