no those are just normal ol cannibus sativa, they grew fields of it all over the midwest, the bark makes some of the strongest rope and canvas, interestingly canvas comes from the word cannabis, because back in the day almost all sails on boats were made from hemp cloth. the inner stem is very woody and an acre of hemp can produce as much paper pulp in 3 months as an acre of rainforest can produce in 300 years. also the seeds are rich in omega fatty acids and are used in birdseed granola and cearal in many other countrys, the oils pressed from the seeds burns brightly and one would think they would make an ideal canidate for e85 since a single 14 foot hemp plant can put out pounds of seeds as apposed to corn wich puts out reletively little compared to the amount of space it takes to grow one. corn is planted 6 inches appart in 3 foot rows, hemp is planted like 4 inches apart in 4 inch rows, as they are encouraged to grow as straight, tall, and branchless as possible, to make the finest fiber. also hemp takes less fertalizer and pesticides to grow, as well as providing a new crop for our farmers to grow. the government thinks paying farmers to NOT grow anything on there land is the best way to raise crop prices (stupid!!!) when those farmers could be growing something infinately usefull that would be worth a lot of money and allow for higher prices on crops. not to mention you would have a hard time growing marijuna crops indoors or out within miles of a field, as the polen goes everywhere.
sorry im a bit obsessed, lol the hemp around here grows very tall, at least 12 feet high in some patches, many of the patches are several acres of pure wild pot plants. the buds are thick, purple and pink colored, with a very sweet bubblegum smell and a thick coating of tricomes on the buds, unfortunatly you could make a pound of hash and smoke it and it wouldn't get you high at all.
