Hemp Seed Growing Tips

Seed Storage

Store your seed someplace cool, dark and dry. Don’t store them next to a water heater, air vent, refrigerator or anywhere that blows or radiates warm or cold extremes. Moisture is the biggest threat to seed storage, so keep seed sealed in original waterproof packaging and away from potential moisture. Freezing is not recommended. Refrigeration can be OK if at optimum temperature and humidity, but not generally not recommended as it can damage the seed.

Test Your Soil

It is advisable to get your soil tested before planting. Make sure to test for metals, sulfur, potassium sulfate and rock phosphate levels. For the most reliable readings, perform soil tests either late in autumn or early in spring.

The best soil for growing hemp is loose, well-aerated, and possesses an abundance of organic matter. The pH level of the soil should be between 6.0-7.5. If you are growing in sandy soil, be aware that additional irrigation and fertilization will be needed to ensure a successful harvest.

Hemp requires high levels of nitrogen, medium-to-high levels of phosphorus, adequate levels of sulfur, and calcium levels that aren’t in excess. Keep in mind that hemp is a plant that is responsible for a process known as phytoremediation. This means that hemp will soak up whatever is in the soil it’s planted in. That’s why it is so important to know what’s in your soil, especially on previously planted crop ground where chemicals have been applied over the years.


Pick the best date to plant your crop, making sure the danger of frost has passed. It is necessary to till the soil before planting. Prepare a firm, shallow bed for the most uniformity in seeding depths, similar to planting clover or alfalfa. Sow seeds directly in the soil at a depth of around 1/2 to 3/4 inch. If you sow seeds mechanically, you can use conventional seeding equipment and either a grain drill or a corn planter will suffice. Once the seeds are planted, it is recommended to roll and pack the soil.


Hemp requires 20-30 inches of rainfall during its growth cycle. If precipitation is less than this, irrigation will be necessary. Be aware that the absorption of water increases each day until flowering begins. Once the plant begins to flower, water absorption decreases significantly, and then increases again as the time to harvest approaches.


Harvesting hemp is a critical stage for CBD production. The presence of molds and mildews will lower the value of hemp biomass, so a timely harvest is essential. There are visual clues on the hemp bud that growers should monitor. When trichomes on the hemp bud shift from white to milky white it may be time to harvest. Weekly testing of CBD content is recommended and can inform the grower of when harvest should be initiated.


Cut individual branches and hang upside down in a cool, dry environment. Ideal temperatures for drying are between 60-70 degrees Fahrenheit, with humidity at 60% or less. It is also important to have continuous airflow, which will help to prevent mold and mildews.
