The amount of water you need will depend on your region's climate, the growth stage of your hemp plants, and your irrigation system. As mentioned, drip irrigation requires the least amount of water, but you will still need between two and three gallons of water per plant per day during peak growing season. Keep in mind how often you water your plants and note this in a log. Have your marijuana plants have an irrigation schedule as they grow out of the seedling stage, watering every two to three days is ideal.
The amount of water needed depends on the weather, but it's best to calculate two to three gallons per day, per plant at maximum consumption. You can't run out of water when plants need it most. Hemp has great potential to compete with crops such as corn, cotton and soybeans, but as the industrial hemp supply chain builds, those crops are not going anywhere, Campbell said. Purdue University's Hemp Project reports that most hemp varieties need between 25 and 30 inches of rain a year, especially in the first few weeks of life.
Although hemp can be grown in the same field continuously, assuming that the soil is suitable for hemp production, first of all, it would be better to grow it in rotation to reduce the risk of increasing the pressure of insect pests and fungal inoculum. While many growing operations have existing irrigation systems, farmers looking to add hemp to their crop rotations often seek to integrate irrigation equipment that is ideal for hemp production. Learning to grow feminized hemp requires practice and repetition, as well as the knowledge to select quality feminized hemp seeds for your growing efforts. Hemp is not as immune to drought as its supporters claim, according to a soil researcher at Colorado State University who analyzed two years of Colorado hemp production.
