Agricultural Info About Hemp

The cultivation of Hemp for fiber

Hemp is known as a bast fiber plant, meaning there are commercially useful fibers in the stalk. Hemp is an annual plant that must be grown from seed each year. The seed is planted in the early spring once the soil is warm. Hemp grown for hemp fiber requires a well prepared seed bed high fertility, good drainage and soil with good amounts of organic matter. Hemp typically does not require herbicides, pesticides or fungicides when planted early at a high plant population.

Hemp grows quickly and can reach heights of 10 to 12 ft. in 75 to 90 days. When hemp is grown for fiber in Ontario the crop is cut down in August and is allowed to lie in the field to cure through what is called the retting process. Retting involves allowing moisture and heat to activate microorganisms that dissolve the naturally occurring glues in the stalk that hold the hemp fibers together. The crop is turned so the retting process takes place evenly. The hemp stalks are baled once the retting process is complete and stored in dry covered storage on the farms. The bales of hemp stalks are delivered to the processing facility on a year round basis.

For further information on the cultivation of hemp see the OMAFRA website.

Contracts for Growing Hemp

Hempline Inc. contracts farmers within our area to grow hemp stalks for us. The contracts are established prior to the crop being planted. A predetermined price is paid for each ton of baled hemp stalks produced. The growers must produce the baled hemp stalks according to our specifications. Premiums are paid to the growers according to the delivered conditions of the baled hemp stalks.

At this time we do not contract hemp production outside of a 100 km radius of our processing facility at Delaware, Ontario, Canada. This is due to the cost of transporting the baled hemp stalks long distances and the added expense of inspecting each field. If you are within our growing region and interested in producing hemp on a contract basis please contact us.
