Google works: http://extension.oregonstate.edu/catalog/html/sb/sb681/ is titled "Feasibility of Industrial Hemp Production in the United States Pacific Northwest"
From a brief look, major factors are good irrigation and fertile soil. However, with the "optimum yield" rainfall being 500-700mm (20"-28") we may be a bit too wet on the east side (so far we've recorded over 20" this month!). The paper also indicates loose, fertile loam as the ideal soil, with lower and uneven yields for heavier, poorly-drained soils. Probably find some microclimates on the Big Island that will work well though.
