Case Studies

featured-image-container-farm

This is the best guide to shipping container farming and agriculture, without question. It isn’t a short article, but it’s extremely comprehensive and educational. Not only do we explain what container farms are and what problems they solve, but we also share over 20 companies involved in container farming, and even discuss the option of building your own. 

Let’s begin by saying that shipping container agriculture is one example in a long list of interesting applications for cargo boxes. And while the most common type of container agriculture is crop farming, there are several options for non-plant agriculture like fish or even protein-rich insects!

The point is that containers offer a way to provide a tightly managed ecosystem for whatever plant or animal species you’re hoping to grow or raise. Just like you probably find yourself being most effective and productive when you have good lighting, the right air temperature, and the perfect background music.

ideal working environment

If an ideal work environment makes you perform better, wouldn’t it be the same for agriculture?

Agriculture is really no different. Plants and animals can certainly survive in many environments, but they grow best in specific conditions. And a shipping container is one tool that can be used to help create those ideal environments.

But before we get too deep in the details of how shipping containers are a good fit for agricultural projects, we need to take a step back and understand the problem that container growing is trying to solve.

To do that, we’ll start by discussing Controlled Environment Agriculture (CEA) through the lens of plants (since that’s where most attention is focused), although many of the same ideas apply to non-plant agriculture as well.

Introduction to Controlled Environment Agriculture

What is Controlled Environment Agriculture?

The purpose of CEA is to provide the optimal conditions necessary for crops to thrive throughout their development.

Think about the things that keep farmers up at night: the weather, disease, bugs, animals, etc. Now, think about the things consumers care about when purchasing produce: flavor, freshness, etc.

CEA allows farmers to have much tighter control over a lot of these factors instead of hoping for the best. It’s about removing risk and chance from the growing process.

Out with the bad, in with the good!

Now there are a lot of people who think that practically speaking, CEA just means trying to grow as much stuff as possible in a small space. And while that’s not completely untrue, that’s more of a result than the main goal.

Instead, CEA is really about higher quality food that’s grown closer to where it will be consumed and in a sustainable way that uses the least amount of resources. Those resources include water, energy, space, labor, and capital (money).

Controlled Environment Agriculture Inputs

The first word of the CEA acronym is ‘controlled’, and it is what separates CEA from traditional agriculture. But you might be curious as to what exactly is being controlled. The main input variables that CEA systems attempt to control are sometimes collectively referred to by researchers are ‘climate recipes’:

  • Temperature: As any gardener knows, extremely hot or cold temperatures can be detrimental to plants. But less than ideal temperatures can stifle their growth without actually killing them. Therefore, tightly controlling the air, water, and even plant temperatures can affect the health and productivity of the crop.
  • Humidity: If you’ve read our article on shipping container condensation, you already understand the relationship between temperature and humidity. In addition to corrosion of metal, humidity can also affect the health of plants, which is why controlling it is so important.
  • Carbon dioxide (CO2): Carbon dioxide is an input (along with light) to the photosynthesis process in plants. Controlling the amount of carbon dioxide in the CEA air helps make plant growth more successful.
  • Light: Light is the other photosynthesis input, and most CEA applications involve artificial light, typically from LEDs. Light can have varied intensity (brightness), spectrum (color), and duration (timing). Some CEA systems with computer-controlled lights actually convert to, for example, 16-hour days to increase crop productivity!
  • Nutrients: Nutrients are delivered via water for hydroponic systems, but can also be delivered via soil as well. Either way, farmers are able to control the composition (which nutrients are used), concentration (how strong the nutrients are) and pH (acidity or alkalinity) of the nutrients delivered to crops

Specific Types of Controlled Environment Agriculture

A controlled-environment agricultural system can be simple or sophisticated. Just putting plastic film on the ground over crops is technically a form of CEA. On the other end of the spectrum, you have computer-controlled, sealed facilities that precisely meter every part of the environment.

Likely the most common type of CEA is the common greenhouse. In all of these cases, the important distinction is that several of the above environmental variables are being intentionally manipulated for a desired outcome.

When we talk about CEA, there are several types of alternative agricultural methods that are also part of the conversation. These include:

  • Hydroponics: Growing plants without soil, either by having the roots directly suspended in nutrient-filled water or having the roots support in an inert medium like gravel
  • Aeroponics: Similar to hydroponics, but the plant’s roots are suspended in air and regularly sprayed with a fine mist of nutrient-filled water
  • Aquaculture: The farming of aquatic plants and animals like algae and fish under controlled conditions, as opposed to something like commercial fishing which takes place in open-water
  • Aquaponics: A combination of hydroponics and aquaculture that involves aquatic animals, bacteria, and plants in a symbiotic mini-ecosystem. A common application is fish that are fed outside food, and whose excretions (with the help of bacteria) are converted into plant nutrients that are given via hydroponic methods

Additionally, there are also some adjacent ideas that aren’t exclusively part of CEA, but are often used in conjunction with it:

  • Vertical Farming: Simply put, it is growing plants in vertically stacked layers. While in most cases this implies growing crops indoors as a CEA application, it could be used outdoors as well.
  • Urban Farming: The process of growing and distributing crops in an urban environment, placing people closer to the source of their food. Given the high land costs in urban areas, CEA is often used in conjunction with urban farming as a way to increase the crop yield.
  • Sustainable Agriculture: Farming with an eye toward resource conversation, ensuring that farming activities today don’t adversely impact the ability of future farmers to grow healthy produce of their own.
  • Cyber Agriculture: The application of cutting edge technology like artificial intelligence (AI) and machine learning to create computerize agriculture, allowing software to determine the conditions that will result in a specific outcome in a plant (like a specific flavor, or enhanced medicinal qualities).
  • Robotic Farming: The use of electromechanical robots to handle the maintenance and care of plants, whether indoors or outdoors.

This isn’t science fiction, it’s a real robot farmer from a real company

Clearly, the umbrella of what constitutes CEA is pretty large. That breadth of possibilities is also what is helping drive CEA innovation in many different ways.

Controlled Environment Agriculture Research and Development Activities

If you’re just now learning about CEA, you might be surprised to find out just how much attention is being given to it these days.

While CEA is practiced by many backyard hobbyists, it’s also the focus of serious university research. Examples include:

Additionally, several startups with substantial Venture Capital funding are hard at work in this market, such as:

venture-capital-money

Investor money is pouring into controlled environment agriculture

There is serious money and time being spent to understand and improve CEA. This will help us have better agricultural systems that produce the food and other products we consume.

Controlled Environment Agriculture Benefits

With us so far? In CEA, farmers are intentionally manipulating the environmental variables we previously discussed. Why would they do that? After all, it’s not simple or cheap to do so necessarily.

If it wasn’t already obvious, farmers go to the trouble of thoughtfully rationing out the amounts of the above inputs because there are tangible benefits to be gained. Below are a few examples of how CEA can improve on existing agricultural methods:

  • Productivity: CEA increases the productivity of a farm, usually expressed as pounds of produce per square foot. It does so in three ways: increasing the density of plants that coexist in a given space (usually with things like vertical farming), by shortening the growing season (thanks to better nutrients and lighting), and also by increasing the crop yield (ideal growing conditions lead to healthier plants with more growth).
  • Flavor: By adjusting some of the input variables, farmers and scientists have come up with ways to develop distinct flavors out of the same crop. It’s the same phenomenon as wines that have a specific taste in certain years because of the weather experienced by the grapevines. It enables consumers to consistently have access to better or different tasting produce than they would normally find.
  • Freshness: Locating farms closer to the consumers that will eat what is grown inside ensures that transportation time (and the cost of both miles covered and refrigeration required) is minimized. This also means that produce can be grown and picked for optimal freshness instead of the hardiness required to survive long-distance journeys (which in turn means the produce retains more of its color and nutrients).
  • Availability: CEA removes the effects of climate, location, and seasonality; meaning, you could theoretically have whatever produce you wanted at any time of year, in any location. Arugula in Antarctica or strawberries in space are both feasible. Extreme weather areas, non-arable land, and dense urban environments are all possible applications.
  • Traceability: Consumers increasingly desire traceability in their food, meaning knowing where it came from, who grew it, how long ago it was picked, etc. These location-conscious buyers are sometimes called locavores and are having an important impact on food sourcing. When the farm is just down the street rather than hundreds or thousands of miles away, making food ‘local’ and from a company you believe in and trust is much easier.
  • Purity: Closely controlling what goes into the crops means farmers also have control over what does NOT go in as well. Things like pesticides and herbicides are no longer required to prevent bugs and weeds from attacking the crops.
  • Security: In one sense, CEA provides physical security by preventing losses from animal vermin or human theft. In another sense, it promotes food security by stabilizing future harvest quantities through the elimination of risks like droughts or freezes.
  • Water Conservation: Since most CEA systems are closed or semi-closed systems, farmers can precisely control the water entering and leaving the overall system while preventing excess watering on adjacent areas. More importantly, they can recycle the water that IS used over and over again, greatly reducing overall water usage.

Overview of Shipping Container Farming

People dedicate entire careers to CEA, so we aren’t going to be able to cover every detail or possible application here. However, we hope you now have a solid understanding of what CEA is and why it is important.

Hopefully, your brain isn’t fried yet, because we’re actually just getting started! If you’re wondering how CEA fits in with shipping containers, you’re about to find out.

Why Shipping Container Farms?

Let’s say that someone wanted to move forward with a mature CEA project, meaning more than just a simple greenhouse. One of the first decision points would be choosing what structure to house the CEA system.

You’d need some kind of building or box to hold everything and separate the outdoor ecosystem from what you’re creating inside. You could custom-build something, but your expertise is really what goes inside the box, not the box itself. You could hire a company to design and manufacture the perfect space for you, but that’s expensive unless you have hundreds of customers.

Instead, there are some great reasons why many researchers and companies have looked to shipping containers to fulfill this role:

  • Modularity: The ease of transporting and even stacking containers are benefits not just applicable for container homes, but for container agriculture as well. If you want to place a container farm in a parking lot, but later move it to another location, that’s easy. If you want to stack several cargo farms together, or even use them in conjunction with regular shipping containers for equipment storage, that’s no problem either.
  • Size: Shipping containers are a good size for indoor farming applications. They are wide enough to allow a central walking path with growing areas on each side that are at arm’s length front to back. They are tall enough to support multiple levels of vertical farming, while short enough that the top levels could be accessed with a simple step stool or platform. And they are large enough to support the agriculture needs of likely hundreds of people.
  • Commoditization: Used containers are cheap and plentiful, and new containers while more expensive, have pricing that is known and stable. If you wanted to start a container farming operation now and later expand, you could be reasonably confident that you could find equivalent containers in the future at affordable prices. If you wanted to add operations in a new geographic location, you could probably find empty containers there too.

The idea of using cargo containers for farming has already been explored by inventive companies like Ikea and researcher groups like the MIT Media Lab. And don’t forget about unique projects to combine a container and greenhouse into an aquaponics system with natural light.

Ford-container-farm

Even Ford has a shipping container farm

It’s clear there are some qualitative merits to the idea of using containers for farming. Now, let’s talk about the quantitative, financial reasoning behind container growing.

The Economics of Shipping Container Farms

The economics of CEA overall are still being debated and studied, and using shipping containers as a path toward CEA doesn’t instantly cure all of those issues. As we always say, shipping containers aren’t perfect and have inherent strengths and weaknesses.

Coupled with the difficulty of growing in containers is the difficulty of running a business in general (given that most container farms are run as businesses). Just like businesses in every other industry, it should be no surprise that several shipping container agriculture companies have gone out of business over the past few years such as Local Roots, Indoor Farms of America / Grow Trucks, and others.

Despite controlling most environmental variables, container farming still exposes owners to most of the marketplace and economic variables that traditional farming faces. So when you think about the economic viability of a container farm, you need to focus on key decisions and costs.

Important Decisions to make about a Container Farm

Important choices include which crops to grow, where to locate the container farm, how to price, and how to advertise effectively to find the right consumers. These choices will impact costs, but they predominantly affect revenue.

Some of the often neglected choices are the small day-to-day decisions that have to be made to operate the container farm successfully. Daily tasks required to actually grow the crops can’t be taken for granted.

In some ways, shipping containers farms have less margin for error than regular farms. When you’re operating at very high efficiencies, mistakes tend to be amplified, but so are the rewards. On the upside, the accelerated growing time and year-round growing season mean you don’t have to wait an entire year for the next chance to plant.

Whether you’re farming it yourself or hiring employees to run it for you, ensuring you have the ability to consistently grow high-quality produce is the issue that everything else hinges on.

Costs of Shipping Container Farm

For the cost side of the equation, we’ll divide outflows into two categories: capital expenses (commonly abbreviated CAPEX) and operational expenses (commonly abbreviated OPEX).

Capital expenses are the large, upfront costs needed to get the container farm started. In most cases, this is just the acquisition cost to buy the actual container farm and associated equipment that is needed to run it.

You can expect to spend around $50k to $100k for most pre-made 40-foot commercial container farms. These CAPEX costs are one-time, or at least, once over a period of many years until something needs to be replaced.

Operational expenses are much different. These are the costs required to run a container farm you already have. Common OPEX items include seed, fertilizer, water, packaging, advertising, etc. But by far, the largest operational costs are energy and labor.

Container farms need to have their own sources of light and water distribution while being kept at a temperature and humidity often very different from what’s outside. The energy inputs required to do all of these things can be significant.

Research has shown that at least for the midwest United States, the majority of energy is used for heating and cooling (around 79% of the required energy) and the balance is used for lighting, water pumps, etc. This split will vary depending on where you’re located (a Mediterranean climate will be easier to heat and cool than a tropical or arctic climate). And additionally, the cost of purchasing energy (in most cases, electricity) can vary significantly from place to place.

However, spending more upfront (CAPEX) on insulation should reduce the heating and cooling expenses (OPEX). If you’re planning for an extreme climate, this investment might be worth it.

Needless to say, there are a lot of factors that go into running a shipping container farm. Those interested should spend significant time on a feasibility study and business plan to ensure that they aren’t just falling in love with a sexy idea, but a realistic business opportunity.

Building a DIY Container Farm

Given that a lot of Discover Containers readers have at least a partial interest in do-it-yourself projects, it’s natural to think about building your own shipping container farm. Is it possible to build your own container farm? Absolutely. Is it a good idea for you? Keep reading.

To begin, we’re going to assume that your potential DIY container farm is based on a hydroponic system. The number one question you need to ask yourself is, “Do I have experience with hydroponic growing or do I mind getting that experience slowly on my own?”

If you have lots of free time and a high-threshold for frustration, a DIY approach may be for you. While a container farm system, in theory, is fairly simple, getting everything to work together and without requiring constant supervision will be a chore.

Let’s talk about the basic setup you’d need:

  • Growing System: Growing chambers, trays, racks, or shelves
  • Irrigation System: Pump, reservoir, nutrient bins, valves, and piping
  • Lighting System: LED lights and wiring
  • Atmospheric System: Shipping container, insulation, air conditioner/heater, ventilation
  • Control & Monitoring System: Humidity, temperature, alkalinity, and light sensors along with controls systems or alarms

This quote from Fast Company is indicative of the uphill battle you’d face purchasing, integrating, and operating all of these systems into a profitable venture:

Given the hefty price tag of developing proprietary growing technologies, not to mention renting pricey urban land, underwhelming harvests (which are common among startups still tinkering with their growing systems) can be financially devastating.

So, for many people who are interested in container farming, purchasing a turn-key system from a manufacturer will be the best pathway forward. Being able to immediately produce crops profitably will help immensely with a container farm’s financial viability. While you may be able to find a used container farm, the market is small enough that most people end up buying new.

Shipping Container Farming Companies

In order to provide the type of high-quality guide we’re known for at Discover Containers, we’ve reached out to companies that specialize in container farms to get more detailed information. This is by far the most exhaustive list of container agriculture companies you’ll find anywhere!

Note: For the most part, we’ve left off the numerous independent farms that have purchased their container farming system from one of the included companies. Instead, we’re focusing on the larger manufacturers and the smaller operators who created their own systems.

In this section, some of the companies that we highlight manufacture and sell shipping container farm systems to businesses or individual farmers. Other companies have made their own container farms themselves and are instead in the business of selling their harvested products.

Below, we share what we heard from these companies when we asked them more about what they do and why they use shipping containers. For those we weren’t able to reach directly, we’ve shared a short summary based on publicly available information. As you might expect, most of what you’ll see are hydroponic shipping container farms. Enjoy!

AgriCool – La Courneuve, France

Agricool is a container farm based in the Paris metro area that currently specializes in strawberries. Their strawberries are available for sale in several areas around the city and can even be delivered via a partner company.

FarmBox Foods – Castle Rock, Colorado, USA

FarmBox Foods is merging technology and agriculture to change the way we farm. When compared to traditional farming, FarmBox Foods’ fully automated, vertical hydroponic shipping container farms are more environmentally friendly—greatly reducing water usage and the carbon footprint associated with food transportation.

Capitalizing on global transportation standards and their hyper-efficient insulation, shipping containers are the ideal mobile farm. These shipping container farms provide year-round, locally-grown produce that can create new farming careers and supply food deserts with much needed fresh food.

Using an entirely climate-controlled system allows the farms to operate in virtually unlimited locations around the world—from the densest of cities to remote, harsh environments—without adversely impacting food production.

In 2020, FarmBox Foods will debut the world’s first gourmet mushroom farm housed entirely within a shipping container. This innovative unit will produce over 300 pounds of oyster, shiitake, lion’s mane, and king oyster mushrooms per week.

Contributing to the movement of food decentralization, mushroom container farms will allow communities to regain control of their food supply.

With growing academic research on the positive effects of psilocybin on mental well-being, FarmBox Foods is also exploring the possibility of launching a psychedelic mushroom container farm in the future.

Pure Greens – Phoenix, Arizona, USA

Pure Greens was founded by Damon and Taisiya Jacobson in 2015. We got the vision of growing crops in ocean shipping containers in prayer. Due to unpredictable weather patterns, it has become a challenge for many farmers to produce crops. We created the Pure Greens Container Farms as we saw a need to improve the accessibility to fresh and locally grown produce in the US and around the world.

Our container farms allow farmers to grow year-round in any weather: extensive heat conditions as in Arizona or very cold temperatures as in Alaska. Unlike greenhouses or outdoor farming, Pure Greens Container Farms are climate controlled. This allows the grower to monitor the indoor environment in the farm, which is done through an app on your phone or on your computer.

Pure-Greens-Container-Farms

The Farms take up very little space, can be placed anywhere and produce crops in all climates, year-round within a sustainable growing environment. Pure Greens Container Farms are designed to grow leafy greens, herbs, and microgreens.

With more than 20 years of experience with specialized shipping container modifications and design, we are set apart from our competitors, as we’re able to fabricate the entire Farm in house. We have our own engineers, welders, and electricians which makes our manufacturing process efficient and timely. We offer several different layouts and can custom-build specific layouts and specifications.

Our Container Farms are ideal for growers, entrepreneurs, kitchen chefs, schools or anyone who has a desire to grow crops but doesn’t have the space or environment necessary for an outdoor farm.

Rocky Mountain Micro Ranch – Denver, Colorado, USA

Rocky Mountain Micro Ranch is Colorado’s first and only edible insect farm, founded in 2015. Our “micro ranch” is a used, retrofitted 40-foot high-cube shipping container. Inside, we raise the edible insects that we sell to chefs, food makers and anyone who loves delicious, sustainable food.

We make products from mostly whole, roasted insects, including chocolate-covered insects and even a pasta made with cricket powder. We previously raised crickets, but now focus on mealworms. Food production is done at a commercial kitchen – the shipping container is totally dedicated to insect farming!

Rocky-Mountain-Micro-Ranch-inside

Inside the container, the insects are raised in plastic trays

Growing bugs in a shipping container has a learning curve: insects are ectothermic or “cold-blooded,” and it’s crucial to keep a constant temperature and humidity with insulation, environmental controls, and air circulation. We also connected a solar thermal water heater to the roof and run a glycol and water mixture through baseboards to heat the container.

Rocky-Mountain-Micro-Ranch-container

Even if it’s freezing outside, the insects in the micro ranch are kept at the perfect temperature and humidity

Given the expensive real estate in booming Denver, creating a small starter farm that could be moved (and has been!) made a lot of sense for a self-funded startup farm like ours. We will continue to farm in the container, but future larger micro ranches may be housed in buildings to be able to scale vertically.  We think these insect farms have just as much potential for urban farming as other companies making shipping container farms.

Ship Shape Urban Farms – Mobile, Alabama, USA

Shipshape Urban Farms (SUF) is a hydroponic farming corporation, providing fresh local produce to consumers along the Gulf Coast with strategies to expand into new markets through the sale of patent-pending, hydroponic Container Gardens.

Ship-Shape-Urban-Farms-container

ShipShape’s container farms utilize horizontal growing shelves to maximize the number of plants that can be grown at one time

Shipshape’s hydroponic “Container Gardens” are unique in design and layout, growing healthier plants in larger quantities, in a reduced footprint versus conventional farming. The technology is supported by the agri-scientist, designers, and computer scientists that perform ongoing R&D on new crops and methods of production.

The Container Gardens are built in a 320 square foot up-cycled, high cube shipping container and produce the equivalent of a 3.4 acre farm (148,104 Sq Ft) in an enclosed environment.
