Introduction
Hey there, readers! Today, we’re diving into the world of hemp cultivation in high tunnels, a technique that’s gaining popularity among growers. If you’re curious about this innovative approach to growing hemp, you’ve come to the right place. We’ll cover everything you need to know, from the basics to advanced tips and tricks.
What is a High Tunnel?
A high tunnel, also known as a hoop house or polytunnel, is a semi-permanent greenhouse-like structure made from a metal frame covered with plastic sheeting. It provides a controlled environment for growing crops by regulating temperature, humidity, and light exposure.
Benefits of Growing Hemp in High Tunnels
1. Extended Growing Season
High tunnels protect hemp plants from harsh weather conditions, extending the growing season. This allows growers to produce multiple harvests per year, increasing their profitability.
2. Controlled Environmental Conditions
The enclosed environment of a high tunnel enables growers to control factors such as temperature, humidity, and ventilation. This optimal environment promotes plant growth and prevents pest and disease outbreaks.
3. Higher Yields
By providing a stable and optimal growing environment, high tunnels result in higher hemp yields compared to outdoor cultivation.
Considerations for Building and Maintaining High Tunnels
1. Location and Size
Choose a location with good drainage, sunlight exposure, and access to water. The size of the high tunnel depends on the scale of your operation and the number of plants you plan to grow.
2. Ventilation
Proper ventilation is crucial for maintaining optimal humidity and temperature levels. Install fans and vents to ensure air circulation and prevent condensation.
3. Lighting
Hemp plants require ample sunlight, so adequate natural light is necessary. If natural light is not sufficient, supplement with artificial lighting.

FAQ About Hemp Grows High Tunnel
1. What is a high tunnel?
A high tunnel is a covered agricultural structure that provides an extended growing season and protects crops from harsh weather conditions. They are typically made of a metal frame and covered with a clear or opaque material, such as polyethylene or polycarbonate.
2. Why grow hemp in a high tunnel?
High tunnels provide several benefits for hemp growers, including:
- Extended growing season
- Protection from pests and diseases
- Improved temperature and humidity control
- Increased yield and quality
3. What size high tunnel do I need for hemp?
The size of the high tunnel you need will depend on the size of your operation and the number of plants you want to grow. A general rule of thumb is to allow 25-30 square feet of growing space per plant.
4. What type of cover material is best for hemp in a high tunnel?
For hemp grown in a high tunnel, a clear or opaque cover material is recommended to provide optimum light transmission. Polyethylene and polycarbonate are both commonly used materials.
5. How do I ventilate a high tunnel for hemp?
Ventilation is crucial for maintaining a healthy environment in a high tunnel. Proper ventilation can be achieved through the use of fans, vents, and passive ventilation techniques.
6. How do I heat a high tunnel for hemp?
Heating may be necessary in colder climates to extend the growing season and protect plants from freezing temperatures. Various methods of heating can be employed, such as propane heaters, wood stoves, and under-bench heating systems.
7. How do I irrigate hemp in a high tunnel?
Irrigation is essential for maintaining optimal moisture levels for hemp plants. Drip irrigation and overhead irrigation systems are commonly used in high tunnels.
8. What pests and diseases are common in high tunnel hemp?
Common pests and diseases in high tunnel hemp include spider mites, aphids, powdery mildew, and Botrytis. Integrated pest management practices should be implemented to prevent and control these issues.
9. What are the benefits of using a high tunnel for hemp cultivation?
High tunnels offer numerous advantages for hemp cultivation, including increased yield and quality, reduced labor costs, and protection from environmental factors.
10. What are the challenges of growing hemp in a high tunnel?
Challenges faced in high tunnel hemp cultivation may include initial investment costs, potential disease and pest issues, and the need for supplemental lighting during the winter months.
