🌱 What Is an Underground Greenhouse?

An underground greenhouse, sometimes called a Walipini, is a partially sunken structure that uses the natural insulation of the earth to maintain stable temperatures year-round.

This design was originally developed in Bolivia to help farmers grow crops in the cold Andes climate, and it’s now becoming popular among homesteaders, off-grid gardeners, and eco-conscious DIYers around the world.

By digging into the ground and covering the top with a transparent roof (usually plastic sheeting or polycarbonate panels), the greenhouse captures sunlight during the day and retains heat from the earth at night — drastically reducing the need for artificial heating.

Build a $300 Underground Greenhouse for Year-Round Gardening

 If you live in a cold climate, keeping your garden productive throughout the year can be challenging. Many growers use cold frames, hoop houses, and traditional greenhouses to extend the growing season—but these structures often come with high construction and heating costs. Fortunately, there’s a cost-effective and energy-efficient alternative: the underground greenhouse, also known as a walipini.

What Is an Underground Greenhouse (Walipini)?

The term walipini comes from the Aymara language of South America and means “place of warmth.” Originally developed for the cold, mountainous regions of Bolivia, a walipini is an underground or pit greenhouse designed to harness the Earth’s natural insulation and the power of the sun.

Unlike traditional glass greenhouses that rely heavily on artificial heating, a walipini uses passive solar energy and the Earth’s thermal mass to maintain a stable, warm temperature—allowing gardeners to grow vegetables, herbs, and even fruits year-round, even in freezing climates.

How an Underground Greenhouse Works

The concept of the underground greenhouse is based on simple yet powerful natural principles. By positioning your garden space 6 to 8 feet below ground, you can take advantage of the Earth’s steady underground temperature, which stays warmer in winter and cooler in summer.

Here’s how it works:

• Solar Gain: The greenhouse is aligned to face the winter sun—south-facing in the Northern Hemisphere or north-facing in the Southern Hemisphere. This orientation maximizes sunlight exposure.

• Thermal Storage: The walls and soil absorb heat during the day and slowly release it at night, keeping the temperature inside stable.

• Insulation: The Earth acts as a natural barrier against wind and extreme cold, reducing heat loss and the need for external heating sources.

In simple terms, a walipini is a rectangular pit about 6–8 feet deep, covered by a plastic sheet roof supported by poles or PVC pipes. The rear wall is higher than the front wall, creating a sloped surface that optimizes sunlight penetration. Two layers of plastic (one above and one below the support structure) trap warm air between them, providing additional insulation.

How to Build a $300 Underground Greenhouse

According to the Benson Institute, a U.S.-based sustainable agriculture organization, constructing an underground greenhouse is straightforward and affordable. Their 20' x 74' walipini model built in La Paz, Bolivia, cost only $250 to $300—thanks to community help and the use of inexpensive materials such as UV-resistant plastic sheeting and PVC piping.

Here’s a basic overview of how to build your own walipini:

1. Choose the Right Location

Select a site that receives maximum sunlight during winter. For Northern Hemisphere gardeners, this means a south-facing slope is ideal. Avoid areas with poor drainage or high groundwater levels.

2. Excavate the Ground

Dig a rectangular pit 6–8 feet deep. The back (north-facing) wall should be taller than the front wall to create a sloped roof that faces the sun.

3. Build Retaining Walls

Use rammed earth, stone, or concrete blocks to construct the walls. The thicker the rear wall, the better it will absorb and store heat.

4. Install Drainage

Good drainage is crucial. Add a layer of gravel or perforated pipes at the base to prevent water from accumulating inside the greenhouse.

5. Construct the Roof

Build a sturdy frame using wood or PVC piping, then cover it with two layers of clear, UV-protected plastic sheeting. The air gap between the layers acts as insulation to trap heat inside.

6. Ensure Proper Ventilation

Include ventilation windows or adjustable flaps near the top of the roof to regulate humidity and prevent overheating during sunny days.

7. Add Interior Beds and Shelving

Build raised beds or plant directly in the ground. You can also install shelves for seed trays, hanging planters, or irrigation systems.

Why Choose an Underground Greenhouse?

An underground greenhouse offers numerous advantages compared to traditional above-ground greenhouses:

• ✅ Low Construction Cost: You can build one for as little as $300 using locally available materials.

• ✅ Energy Efficiency: Minimal heating is required, saving energy and reducing carbon footprint.

• ✅ Year-Round Growing: Maintain a steady growing environment for vegetables and herbs even in freezing winters.

• ✅ Durability: The Earth’s natural structure protects your greenhouse from strong winds and harsh weather.

• ✅ Sustainability: A perfect project for off-grid or eco-conscious gardeners.

Tips for Maintaining Your Walipini

To ensure your underground greenhouse thrives year after year:

• Monitor temperature and humidity levels regularly.

• Use mulch to retain soil moisture and prevent temperature fluctuations.

• Rotate crops to maintain soil fertility.

• Clean the plastic roof periodically to allow maximum sunlight penetration.

Final Thoughts

If you’re passionate about sustainable living and self-sufficient gardening, building an underground greenhouse is one of the smartest investments you can make. For just around $300, you can create a year-round food production system that thrives even in cold climates—all while reducing your environmental impact.

Whether you’re a homesteader, a backyard gardener, or someone looking to save on grocery costs, the walipini offers an affordable and eco-friendly path to fresh, homegrown produce every day of the year.

Growing Underground: The Ultimate Guide to Walipini Greenhouses for Year-Round Gardening

Have you ever dreamed of growing fresh vegetables and herbs all year long — no matter how cold, hot, or unpredictable the weather gets? With a Walipini greenhouse, that dream can become reality.

Traditional gardening often struggles against the extremes of nature — freezing winters, scorching summers, and heavy storms can all halt your harvest. But underground greenhouses, known as Walipinis, offer an innovative and eco-friendly solution for consistent, sustainable gardening in virtually any climate.

In this comprehensive guide, we’ll explore what a Walipini greenhouse is, how it works, its pros and cons, and expert tips for designing your own underground garden oasis.

---

What Is a Walipini Greenhouse?

The word “Walipini” comes from the Aymara language of Bolivia and Peru, meaning “place of warmth.” Despite the name, these unique greenhouses provide not just warmth, but a stable, controlled environment for growing food underground.

A Walipini greenhouse is typically built 6–8 feet below ground level, using the Earth itself as insulation. The structure features earthen walls and is usually covered with transparent polyethylene glazing that allows sunlight to penetrate while trapping heat.

This design maintains a consistent temperature throughout the year, reducing the effects of frost, wind, and extreme heat — making it ideal for anyone who wants to pursue year-round gardening or off-grid food production.

---

The Origins of the Walipini

The concept of the Walipini was developed in the 1990s by the Benson Institute, part of Brigham Young University (BYU). The goal was to help Bolivian farmers in the harsh Andean regions extend their growing seasons and achieve food security despite the cold, unpredictable weather.

Since then, the idea has gained global attention among sustainable living enthusiasts, homesteaders, and eco-conscious gardeners seeking efficient, low-cost alternatives to traditional greenhouses.

Why Build a Walipini Greenhouse? The Key Benefits

Building a Walipini greenhouse can transform the way you grow food. Here are the main advantages:

1. Year-Round Growing Capability

Because a Walipini is built underground, it benefits from the Earth’s natural insulation. Soil maintains a relatively stable temperature year-round — typically between 50°F and 60°F (10°C–16°C) — protecting your crops from freezing winters and scorching summers.

That means you can grow vegetables, herbs, and even tropical plants all year long, regardless of your local climate.

2. Energy Efficiency and Sustainability

One of the most compelling reasons to build a Walipini is its energy efficiency. Unlike above-ground greenhouses that require heating systems in winter or ventilation in summer, a Walipini uses passive solar design and thermal mass from the earth to regulate temperature naturally.

This results in significant energy and cost savings, making it a perfect fit for off-grid living or sustainable farming.

3. Protection from Weather and Pests

The underground environment shelters your crops from strong winds, frost, hail, and heavy rains. It also provides natural protection from pests such as aphids, whiteflies, and fungal diseases that often plague above-ground greenhouses.

With fewer pests and more stable conditions, you’ll enjoy healthier plants and higher yields.

4. Space Optimization

For gardeners with limited land, a Walipini greenhouse offers a creative solution. Since most of its structure lies below the surface, it doesn’t consume much above-ground space, allowing you to maintain other uses for your property — or even integrate it into your landscape design seamlessly.

---

Potential Challenges of a Walipini Greenhouse

Like any gardening structure, Walipinis come with challenges that you’ll want to plan for carefully.

1. High Upfront Construction Costs

While operating costs are low, building a Walipini can be labor-intensive and expensive initially. Excavation, retaining walls, waterproofing, and glazing materials can add up — especially if you hire professional help or live in an area with difficult terrain.

2. Drainage and Flooding Risks

Because a Walipini sits underground, drainage is crucial. Poor site selection or improper waterproofing can lead to flooding, which can damage crops and weaken the structure. Always choose a location with well-draining soil and consider adding French drains or a gravel base to prevent water accumulation.

3. Humidity and Ventilation Control

An enclosed underground space can easily trap moisture, leading to high humidity levels that may promote mold or mildew growth. Effective ventilation systems, including adjustable vents or solar-powered fans, are essential to maintain air circulation and prevent condensation.

4. Accessibility and Maintenance

Because Walipinis are built below ground level, access can be challenging, particularly for older gardeners or anyone with mobility concerns. Designing gentle ramps or wide stairways can make daily maintenance easier and safer.

---

How to Choose the Perfect Location for Your Walipini

Selecting the right site is key to your underground greenhouse’s success.

1. Maximize Sunlight Exposure

In the Northern Hemisphere, orient your Walipini so that its longest wall faces south to capture the most sunlight, especially in winter. Avoid shade from nearby trees, fences, or buildings.

In the Southern Hemisphere, reverse the orientation — the longest wall should face north.

2. Check Soil and Water Table Conditions

Choose a site with stable, compact soil that can support the structure. Avoid areas with a high water table, as they are more prone to flooding and may compromise structural integrity.

3. Plan for Easy Access

Your greenhouse should be accessible for construction, daily care, and harvesting. Also, consider proximity to water and power sources if you plan to use irrigation systems or grow lights.

---

Managing the Microclimate Inside Your Walipini

Even with natural insulation, you’ll need to fine-tune your underground greenhouse’s temperature, light, and humidity for optimal plant growth.

1. Temperature Regulation

Use insulating materials such as hay bales, foam boards, or insulated panels on exposed walls to help maintain steady temperatures. You can also add thermal mass elements like large water barrels or stone walls that absorb and release heat gradually.

2. Ventilation and Humidity Control

Install adjustable vents or passive air tubes at both high and low points to create cross-ventilation. Natural airflow keeps humidity under control while also cooling the greenhouse on hot days.

If humidity remains high, a solar-powered fan or dehumidifier can make a big difference.

3. Water Management

Overwatering is a common problem in closed environments. To avoid excessive humidity, check soil moisture levels before irrigating or use a moisture meter. Mulching can help retain moisture while reducing the need for frequent watering.

---

Lighting Tips for Underground Gardening

Sunlight is essential, even for an underground setup. Here’s how to maximize natural and artificial light in your Walipini:

• South-facing orientation ensures maximum sunlight during the winter months.

• Add reflective materials (like aluminum sheets or white paint) to interior walls to bounce light throughout the space.

• In areas with limited winter sunlight, consider using LED grow lights to supplement natural light.

• During hot summer months, use shade cloths to prevent overheating and protect sensitive plants from sunburn.

---

Best Irrigation Methods for a Walipini Greenhouse

Because humidity management is key, efficient watering is essential.

• Drip irrigation systems are ideal, as they deliver water directly to plant roots, reducing evaporation.

• A mulch layer (like straw, wood chips, or leaves) helps regulate soil moisture and prevent excess humidity.

• For small underground greenhouses, manual hand watering gives you precise control over water usage.

---

Final Tips Before You Build

Before breaking ground on your Walipini project, make sure to:

1. Check local zoning and building codes — some areas require permits for underground structures.

2. Choose structurally stable soil and plan for proper drainage from the start.

3. Design easy access points for daily gardening and maintenance tasks.

4. Consider installing water and power connections if you plan to automate irrigation or add lighting.

5. Start small — a compact Walipini is easier to manage and can serve as a learning experience before scaling up.

---

Conclusion: Sustainable Gardening Beneath the Surface

A Walipini greenhouse represents more than just a gardening trend — it’s a sustainable, energy-efficient, and climate-resilient way to grow your own food. Whether you’re an off-grid homesteader or a weekend gardener, a Walipini offers a rewarding path to self-sufficiency and eco-friendly living.

With the right planning, proper drainage, and careful temperature management, your underground greenhouse can become a thriving, year-round food oasis — protected from the extremes of weather and built in harmony with the Earth itself.

Baking Soda as a Homemade Weed Killer—Here's How to Use It Successfully

Baking soda can be used as an effective and simple solution for destroying weeds in some situations. This home household item is strong enough to destroy smaller types of weeds. It also has the added benefit of keeping powdery mildew at bay—a fungal disease that is often present on prized landscape plants like rose bushes and lilac shrubs.

Using baking soda to treat weeds is simple, either by applying it straight out of the box or mixing it with a solution to spray over areas you desire to treat.

Understand why baking soda kills weeds, how to use it properly, and what its limitations may be.

Why Baking Soda Kills Weeds

Baking soda's weed-killing properties are partially due to one of its largest ingredients: salt. Salt dehydrates plants if used in sufficient quantities, and eventually kills them by preventing water intake.

If you're sure that you want to kill a weed, drying it out is a suitable option. By drying out the plant completely, it ceases to be able to take up water, effectively eradicating it.

Even though larger plants like shrubs require larger doses of sodium bicarbonate to realize this, caution must be exercised when using baking soda on shrub leaves, particularly when controlling powdery mildew. To create a successful solution for such applications, one should mix one teaspoon of baking soda with one cup of water.

For more gardening advice, subscribe to our free gardening newsletter, which is full of handy hints, tricks, and trouble-shooting tips.

How to Dispose of Weeds with Baking Soda

Baking soda may be applied to weeds in two basic manners:

1. The most convenient process is to simply sprinkle baking soda right out of the box onto weeds (about one teaspoon per weed). To facilitate the adhesion of baking soda, moisten the leaves first so that the baking soda adheres well to the leaves.

2. Alternatively—and better—make a solution by combining baking soda and water. Transfer the solution to a spray bottle and spray directly onto your weeds. This conserves wastage and avoids the drawback of baking soda blowing away while applying, as is the case with the direct-sprinkle method.

Regardless of your chosen technique, always apply baking soda on a sunny day. Rain can wash away your treatment before it has a chance to work its magic. If opting for the spray solution method, mix and apply carefully for the best results.

Naturally, five additional tips to eliminate weeds are, aside from baking powder, there are many other ways to kill weeds naturally.

• Vinegar: Vinegar is a natural herbicide as well. Use vinegar to obtain the best outcomes with high acetic acid.
• With boiling water: This is the cheapest way to kill weeds naturally naturally. However, never forget that it's not selective.
• Suffocation: Black plastic suffocates weeds with plans, etc. It works best with landscape areas that have high weed density and monoculture designs. For example, a plan to suffocate the Japanese knot.
• Hand Powder Weed: It is a very obvious one and is easy to forget. Most gardeners enjoy getting their hands in the soil and in contact with the plants, even though it's a weed.
• Salt Usage: Rather than employing the baking powder, salt is also employed to eliminate weeds (as it is a salt in baking powder, therefore the herbicides will work). Salt is cheaper, and so this might be a smarter alternative.
