Ecofibre's Industrial Hemp Fibre Production Guide. 2. Hemp is a 4 m tall annual, daylight sensitive, fibrous plant. It is a summer crop, grown for Fibre, Grain & Oilseed in many countries. There are over 2,000 lines, with low THC.
That cost gap has narrowed, however. With better screens and technology that helps the plants power themselves by recycling the energy used to suck in water-in a way, like a hybrid car regenerates power from its own motion-the typical cost of running desalination plants can dip below $2,000 an acre-foot.
A seeding rate of 50 pounds per acre is recommended and the field type seed cost is typically $0.35/pound. Plant populations in wide rows should be similar to soybeans, about 4 to 8 plants per foot of row. Field trials were done in Missouri on 30 inch row spacings, and the vine type varieties filled in the row well.
