"Washington also grew hemp (cannabis), like many people of his time. Hemp was considered an important crop and widely used as a source for paper, cloth, rope, ship sails and for many other uses. “Make the most you can of the Indian Hemp seed and sow it everywhere,” wrote Washington in 1794. His whiskey distillery and hemp acreage might remind us that Washington was a down-to-Earth human being, as well as a warrior, statesman and American patriot." 2007 http://tinyurl.com/37s8xg

One thing we know for sure, Washington did not have a grow light;)
