The U.S. controlled environment agriculture (CEA) industry received lots of publicity over the past 10 years. From interviews on CNBC to articles in Forbes, investors and the general business community found interest in an industry that seemed new despite the fact that it was anything but.

(If you are interested in the definition of and more information on the controlled environment agriculture and the indoor ag tech industry, please click here.)

This new interest led to substantial capital invested into greenhouses, vertical farms, and other companies supporting the commercial ag-tech and horticulture industry. All this “noise” made it hard to discern what was real, hype or fabricated by overly creative (yet inspiring) pitch decks.

From this point forward, we must focus on a reset of known information. One that clarifies the reality of our U.S.-based commercial food producing horticulture market. This reset must take into account the benefits of all the money invested between 2017-2022 that led to building new farms.

More importantly, it must encourage people, investors and business innovators to continue focusing on the benefits (mostly to growers or farmers) of our small but still-growing controlled environment agriculture industry.

Note: The following information mentions ornamental and cannabis production because these segments contribute to our industry. However, they are not often included in the definition of controlled environment agriculture, indoor ag or vertical farming.

Let us start with a handful of observations that you are free to comment on below. We will do our best to respond as quickly as possible.

1) The cannabis industry began its path to legalization in 1996 when California legalized medical marijuana. Since then, 40 states followed California in legalizing medicinal use. But the real industry boom began in 2012 when Colorado and Washington legalized recreational use of cannabis.

As of June 2023, 23 states have legalized adult cannabis use. This rapid growth impacted all commercial horticulture because growing cannabis uses the same inputs as all other crops. As such, the industry saw a drastic uptick in the sale of greenhouses, horticulture equipment, irrigation equipment, horticultural lighting and crop consumables (i.e., fertilizers, substrates and pest management products).

The industry also saw massive expansion of companies providing wholesale supply, as well as new horticultural tech companies growing quickly with higher-than-normal profit margins.

2) U.S. interest in vertical farming exploded in the mid-2000s. This was due in part to investment in and formation of Aerofarms in 2004; Dickson Despommier’s 2008 lectures and 2010 book; and numerous inspirational articles, architectural images, and stories from countries concerned with food safety and security. (See the Japan earthquake and tsunami of 2011.)

3) The Netherlands Increased marketing and the promotion of venlo-style, Dutch-designed glass greenhouses as a proven and safe investment for growing select fresh produce. This coupled with early semi-automated leafy green production systems and unique placement of rooftop greenhouses (see Gotham Greens/Whole Foods partnership in 2013), plus the early failures of multiple vertical farms, led to the next round of investments.

4) Controlled environment agriculture went “public” and investment firms stepped up with BIG capital. This sparked big interest and even bigger promises from companies looking to get a piece of the money pie. From greenhouse operators such as AppHarvest and Local Bounti, to supply companies such as Scotts Miracle-Gro (owner of Hawthorne Gardening Company) and Hydrofarm, to investment firms such as Equilibrium Capital, COFRA Holdings and Cox Enterprises, the dollars invested in the industry raised to levels never seen before. We all know that when significant dollars get injected into a market, it often leads to “boom” level interest. (See David Chen’s 2021 comments.)

5) Cheap, abundant capital along with over-promising suppliers and so-called expert consultants chasing dollars led to a boom-industry mentality.

In 2005, UC Berkeley professors Roberta Cook and Linda Calvin published a paper titled, Greenhouse Tomatoes Change the Dynamics of the North American Fresh Tomato Industry. For purposes of this discussion, we will use this paper as a foundation to define industry growth. Reason being, many of the largest investments went into companies that were farms based on assumptions gained from years of CEA industry data.

The reality of this data is that prior to 2010, most of it was based on producing greenhouse tomatoes. Historically, this was a high cap-ex industry with low profit margins that relied on careful cost control, operational excellence, high yields and old-fashioned luck.

The above paper also correctly defines the market as a North American one since the product produced in these facilities competes directly with their field-grown competitors for sales and shelf space. It also stated that U.S.-based greenhouses will be forced to compete with products grown in Canada and Mexico.

All this remains true today (regardless of crops grown). In 2003, about 1,630 acres of greenhouse tomatoes were grown in the U.S. Twenty years later, our data shows a 20-30% drop in this figure. What changed during this time is the number of crops grown at a larger scale. The addition of more peppers, cucumbers, strawberries, leafy greens, and culinary herbs means that the greenhouse production area has increased to about 2,150 acres.

This means that even with all the money spent over the past decade, our production area only increased about 20-30%. It is also important to note that we are not considering the metric tons produced on these acres. Yield improvements of about 20-40% (depending on crop) have been seen over the past 20 years.

The take home message should be, Americans are consuming more tomatoes. American retailers are just importing more and more of them each year. Even the ones we grow in a greenhouse.

Greenhouse Grower recently released an article showing their account of the largest greenhouse vegetable growers. While we think this is a good start, our data shows their information is slightly understated, somewhat incorrect and easy to misinterpret.

We estimate that the USA CEA production area by acres is +/- 2200 acres. We are excluding vertical farms due to lack of data. And we do not count structures that do not have 4 walls, a door and some means of mechanically managing the environment. This means we do not count hoop houses, but we acknowledge there are many successful farmers using hoop houses to profitably produce crops across the USA.

For companies such as Urban Ag News, we are built on the hopes that our U.S.-based controlled environment agriculture industry is sustainable and capable of continued growth. Our data indicates that we still have work to do before we can be considered an independent industry. (We depend on the global commercial horticulture industry, including the ornamental and cannabis industries, to be viable.)

Additionally, the data shows that ag-tech investments face fundamental problems. (See Agfunder Report and state of CEA investments in this article in Produce Blue Book as well as one can download this Pitchbook Report.) To understand these problems, consider Professor Michael Porter’s work on competitive strategy. He states that for an investment to be justified, you need a big enough market — and the portion of that market you can access is where you make your profits. So, for instance, if you produce ag technology only suitable for a small area of production, it is unlikely that you will gain a profitable return.

Remember how in 2003 the data showed 1,630 acres of greenhouse tomato production in the U.S.?. In 2022, only about 1,250 acres of tomatoes were produced in greenhouses. In 2003, four large greenhouse operators controlled 67% of the production acres. In 2022, eight large greenhouse operators controlled 80% of the production acres.

There is significant dependence on a few clients who control most of the acreage for ag-tech companies focused on the U.S. market. This means new ag-tech companies must be accepted by nearly all the commercial greenhouses to be viable.

If the technology targets leafy greens and culinary herbs, then it is important to realize that the 2023 industry is even smaller (just under 400 acres). In addition, the leafy greens industry is further challenged by the fact that most players use different production methods, making it harder to find similarities among farms.

All of this means that true ag-tech companies must be ready and willing to explore new geographies that have similar existing markets, target new crops, or focus on more general technology. The easiest are Mexico and Canada in terms of travel. The hardest is Europe. But do not expect them to accept new ideas quickly, as there are just as many local companies competing for business.

The same competitive strategy applies to greenhouse operators and producers as well. The market is highly competitive and as the data shows, much of that competition is coming from Mexico, Canada or the open field. Greenhouse businesses must be solving a clearly identifiable problem while providing a value proposition (ie product) that is clearly “better, faster or cheaper” than the product that is already existing on the market.

Successful companies need capital, time, people and patience. Dutch companies invest heavily to access U.S. markets. Same goes for horticulture companies from Mexico, Canada, Israel, Spain, China, Sri Lanka and any other areas that can produce horticulture technology, supply, consumables and (yes) fresh produce.

While some might read this article and see it all as doom and gloom, we do not. As stated earlier, we see it as important information to know and understand, so we can accept a reset. Our industry still has tremendous upside.

For the industry to reach its potential, we must understand the following before we can grow:

1) With rising interest rates and increased company failures being announced, investment dollars are harder to come by. We must keep those dollars working and staying in the U.S. (or in your local economy or at least with companies investing in your local industry or economy.)

2) We must increase the number of American-led companies “growing” or operating successful commercial horticulture businesses. The current lack of grower or production leadership shows that we do not have the expertise to run these facilities. Keeping dollars in the U.S. should promote the opportunities and education needed to get interested people into the right positions. If we do not do this, then we must change our current political position on immigration and start making it easier to bring in talent from other countries.

3) Currently, the cost of running U.S. CEA businesses is high because:

Once we overcome these obstacles, we can and will have a thriving industry. After all, we will still have the same problems we faced when people became excited about our industry.

Traditional farms will continue to be impacted by changing climate patterns and extreme weather events. Fresh produce with little to no pesticides will continue to be sought after by consumers. And we will still need to protect our fresh water sources from nitrogen runoff and agriculture (as well as industrial) contamination.
