Building a DIY high tunnel greenhouse on a budget is a simple and affordable project that can grow vegetables and crops even in the dead of winter. The process involves setting up the foundation, assembling the main frame, building the support structure, and attaching high tunnel doors. There are three ways to set up a greenhouse: buy a kit, build it from scratch, or buy a second-hand one.
The most essential hardware components required for constructing a high tunnel or greenhouse include a minimum crew of four, three to pull strings attached to the edge of the plastic film, and the fourth to keep the film flowing over the hoops. Fasten the 2×4 base with 3-inch screws and use a drill and auger to bore 1 ½-inch-diameter holes into the ground inside each corner.
High tunnels feature a single layer covering of greenhouse polyethylene plastic film, roll up side walls, and woven plastic “fabric” end walls with zippers. Our 30 ft. wide mobile greenhouse high tunnel DIY Kits are designed for simple operation and on-farm functionality, configuring to maximize natural ventilation.
In summary, building a high tunnel greenhouse on a budget requires several steps, including setting up the foundation, assembling the main frame, building the support structure, and attaching high tunnel doors. By following these steps, homeowners can create a sustainable and efficient growing space for their plants, even in harsh weather conditions.

What is the difference between a greenhouse and a high tunnel?
A greenhouse and tunnel are two types of growing systems used for plants. Greenhouses grow plants in pots on a table, while tunnels grow plants in the ground. Greenhouses use heaters and powered ventilation systems, while tunnels do not. Haygrove Tunnels, a UK-based company, built tunnels to counter cool rainy growing conditions. The company’s success led to the creation of tunnels worldwide. The purpose of tunnels is to reduce crop loss from heavy rain and start plants growing earlier in spring, allowing for an earlier harvest.
What is the most profitable plant to grow in greenhouses?
Spinach is a lucrative cash crop that can be grown in a greenhouse to protect it from the sun and sell unlimited leaves per season. Baby spinach, which grows well in a greenhouse due to its weak stems, can be served raw or steamed. Microgreens, such as basil, beets, and mustard, are nutritious and delicious vegetables that are typically sold at high prices in restaurants. Growing microgreens in a greenhouse is a lucrative business, especially if you have a ready market and can harvest them within 2 to 4 weeks.
What temperature should a high tunnel greenhouse be?
Tomatoes flourish in temperatures between 70 and 75 degrees Fahrenheit, with a minimum of 55 degrees Fahrenheit. Temperatures exceeding 90 degrees Fahrenheit during the day and 70 degrees Fahrenheit at night can have a detrimental effect on the majority of tomato cultivars.
How much does it cost to build a tunnel in India per km?
Bruhat Bengaluru Mahanagara Palike plans to build a first-of-its-kind tunnel road in the capital city, Bengaluru, with an estimated cost of Rs 8, 043 crore. A Turkish consultancy firm has been hired to prepare a feasibility report, which has been completed and submitted, receiving Rs 4. 70 crore. The project aims to facilitate smoother traffic flow and alleviate congestion issues on the north-south corridor. The tunnel road will follow the existing metro lines and heritage buildings, ensuring no damage to either.
What is the difference between a high tunnel and a hoop house?
A hoop house is a cost-effective and quick way for growers to upgrade their operation. These structures, often called high tunnels, are made from pipe frames and covered with a single-layer poly film. They are placed directly over soil and attached to ground posts, allowing for easy relocation. Hoop houses protect plants from rain, wind, and cold weather, allowing for higher-quality yields for longer periods.
They also maintain uniform temperatures by absorbing and trapping heat from the sun, allowing for earlier planting and later harvesting. Greenhouses, on the other hand, are more complex and require more maintenance.
What are the dimensions of a high tunnel greenhouse?
A high tunnel is tall enough for a person to comfortably walk upright inside and grow trellised crops like tomatoes. It differs from low tunnels, which are 2 to 3 feet tall. High tunnel sizes range from 14 feet x 30 feet up to 30 feet x 96 feet and can vary in design. Some growers construct their high tunnels on skids for crop rotational purposes. High tunnels can vary in size and design, making them suitable for various crop rotations.
How much does it cost to build a high tunnel?
The price of high tunnel kits varies considerably, with costs ranging from $2. 25 to $5. 00 per square foot. This variability is attributed to factors such as tunnel dimensions, features, bow steel thickness, and plastic film type. These kits are available from a multitude of suppliers.
What plants are best for high tunnel?
The most suitable crops for high tunnel production include early-harvest varieties such as tomatoes, cucumbers, peppers, berries, and salad greens. It is notable that fruiting vegetables, such as tomatoes and seedless cucumbers, tend to have higher market values.
What is the most profitable crop for 5 acres?
Micro-farming is a small-scale farming approach that involves cultivating a variety of crops on a 5-acre plot of land. Common cash crops include garlic, bamboo, oyster mushrooms, and ginseng, which are easy to grow and highly valued. Livestock, such as poultry farming, pigs, and turkeys, can also be a profitable venture. Poultry farming provides meat, eggs, and honey, which can be sold in farmers markets due to high local demand. Pigs can be raised comfortably on the acreage, and turkeys are especially lucrative during the holiday season.
Beekeeping is another profitable venture, as it is essential for crop pollination and provides honey, which can be sold for a profit. However, it is important to choose the type of beekeeping that suits your limited space.
Can you use a high tunnel as a greenhouse?
High tunnel greenhouses offer several benefits, including ventilation without a dedicated system, lower costs for construction and operation, in-ground growing, protection from hail, wind, frost, excessive precipitation, and pest pressure, and a more consistent growing environment for plants. They can accommodate in-ground growing, protect seedlings before they are moved into outdoor rows, and provide protection from hail, wind, frost, excessive precipitation, and pest pressure.
In contrast, greenhouses provide a more consistent growing environment for plants, often equipped with climate control and greater insulation values. They can be used year-round if equipped with heating and cooling equipment, offer more protection from the elements due to their complete enclosure and polycarbonate panels or glass, have a solid foundation for growing systems and benches, allow for more plant options, and provide efficient pest management due to the secure enclosure of the space. Overall, high tunnel greenhouses offer a variety of benefits for both indoor and outdoor gardening.
