Hempseed oil, clothes, insulation : Cannabis sativa has so many uses !
Common name : Hemp
Scientific name : Cannabis sativa L.
Family : Cannabaceae
Category : Annual
Cannabis sativa is an annual herbaceous flowering plant indigenous to eastern Asia but now of cosmopolitan distribution. It is used as a source of industrial fiber, seed oil, food, recreation, religious and spiritual moods and medicine. Each part of the plant is harvested differently, depending on the purpose of its use. It can be grown in your garden - but in most countries it is regulated : a legal distinction is often made between industrial hemp, with low concentrations of psychoactive compounds, and actual marijuana. A Cannabis plant in the vegetative growth phase of its life requires more than 12–13 hours of light per day to stay vegetative. Flowering usually occurs when darkness equals at least 12 hours per day. The flowering cycle can last anywhere between nine and fifteen weeks, depending on the strain and environmental conditions.

Identify my hemp

To differenciate marijuana from legal industrial cannabis, just consider its global shape. Industry produces high plants of 2 to 4 meters, while marijuana is low, with large buds.

Sow my hemp

Outside: Make your seedlings in open ground between March and early June, in heated soil. To prepare your seeds, soak them overnight in water. Hemp does not like heavy soil or excessive acidity, so sow in the sun in light soil. If your soil is heavy, work its top by carefully removing the clods after a scratch. Then sow in a finely prepared soil, burying seeds 2-3 cm apart. Tamp the soil with the "back" of a rake to allow the soil water to soak the seed well. Water in very fine rain. Inside: You can sow in theory at any time indoors, but it's better to do it in the spring if you rely on outside light to light up your plants. Otherwise you will need to use lamps to simulate long days. To prepare your seeds, soak them overnight in water before sowing. Then sow in fine potting soil, in pots, burying seeds 2-3 cm apart. Tamp the soil with your hand to allow the soil water to soak the seed well. Water in very fine rain.

Water my hemp

In open soil, watering is only useful at the beginning of cultivation. Be delicate after sowing, use a fine watering cane so you do not move the soil. Watering may also become necessary during flowering and fruiting. In this case water at least twice a week without wetting the foliage.

Repot my hemp

After sowing indoors, when your plants have four true leaves, transplant them into individual pots. Switch to containers of at least two liters filled with potting soil or a mixture of soil, compost and sand.

Thin out my hemp

After a fortnight, remove the plants that are too tight, keep only the strongest, every 20 cm.

Reap my hemp

Hemp seeds are harvested in September, when the seeds at the bottom of the ear begin to detach. Harvest the whole ears. Then, to consume them you will have to shell the seeds. Do not panic, it is possible to do it without any mechanical tools. Gently crush the seeds between two boards or between the table and a board, gently tapping with a mallet to avoid crushing everything. Once the shells are broken, discard the whole thing in water and mix vigorously so that the seeds separate from hulls and sink.

Remove my hemp

After the harvest, you can pull out the plants to leave room for other crops and compost the remains.
