Greenhouses are expensive to build
and operate. As a result, potential
profits are high, but so is the risk
involved. Greenhouse growing is an
intensive form of plant production
and has the potential for high
returns, but crops grown in greenhouses
have exacting requirements
and the markets have
The technical details necessary for
greenhouse growing can be acquired
by trial and error, but there is nothing
like firsthand experience in greenhouse
production to make the venture
more successful. Prospective growers
with no firsthand experience are
encouraged to start small and learn
the technical details first, and then
expand as experience increases.
Wholesale or Retail?

and wholesale growing. Generally,

Opportunities exist in both retail
and wholesale growing. Generally,
retail growing works best if you enjoy
working with people and helping
them satisfy their needs and wants.
Wholesale growing is more feasible
if a suitable retail location is
unavailable or if you have figured
out some way of providing a needed
wholesale product and delivering it
to your customers.
Retail growing and selling
directly to the customer is the easiest
area to break into at present because
growers can obtain higher prices for
their products at the retail level.
Retail growing requires an area on a
paved road which is easy to find and
within a reasonably large population
center. On average, a population base
of about 6,500 people will marginally
support one retail greenhouse outlet.
When evaluating your potential customer
base, consider the size of your
community’s trade area, not just the
size of the town or city. When assessing
competition, count both traditional
full-service greenhouse and nursery
operations, but don’t forget to include
other plant outlets such as chain
stores, feed stores and even some food
stores. It is always easiest to come
into a market as the population base
is expanding, so check local records
concerning past and expected future
trends. Traditional retailing, where
you attempt to buy in all product and
resell it to the customer, is increasingly
difficult because of competition
from mass market firms.
Wholesale production can take
several forms. Wholesale growers
almost always deliver their product to
their retail customers, so transportation
logistics becomes an important
part of the challenge required to
succeed as a wholesale grower.
The customers may be retail greenhouses or
nurseries, florists, grocery stores, chain stores,
landscape contractors or farm store outlets. Many
wholesale growers set up truck routes and stop by
their customers’ businesses weekly during the busy
How Big a Greenhouse do I Need?
Deciding on how much greenhouse space is needed
requires that one must first determine who the
will be. If you find there is room in the market
for your product, then do some quick math to test the
feasibility of the idea. Let’s assume you want to make
$24,000 a year growing bedding plants (two-thirds of
the money) and poinsettias (one-third of the money).
Just guessing, you figure you can make $2.00 per flat
profit on bedding plants and $1.00 per pot on
That means you would need to grow 8,000 flats
of bedding plants and 8,000 pots of poinsettias to
earn your $24,000. Now that you have some very
rough numbers, you can begin to assess the ability to
actually sell that much product. In any given market,
selling the bedding plants at the retail level might be
relatively easy, whereas moving that many poinsettias
could be a challenge. You might choose to
reassess your plan and consider selling 8,000 flats of
bedding plants, 4,000 garden mums and 4,000
This production plan would probably be easier
Now, given that you have estimated a need to
produce 8,000 flats of bedding plants in the spring,
you can work backwards and estimate the greenhouse
space needed. Most bedding plant growers have an
early and a late crop, thus producing two “turns” of
their space each spring. That means that 4,000 flats
would be grown in the first turn and 4,000 in the second
turn. If a bedding plant flat occupies 1.5 square
feet per flat, then 6,000 square feet of growing space
would be needed for each crop. Assuming that 70
of the greenhouse space is in “production space”
and the remainder is in walks and isles, then a
with 8,570 sq. ft. would be needed (6,000 ÷ 0.7

Micro grid for power supply large scale extension.
Alfen has been selected to supply a micro grid to power the large scale extension of Combivliet's tomato greenhouse
complex in Middenmeer. Alfen: "The trends in greenhouse horticulture in the field of automation, scale extensions,
and renewable energy require more and more complex energy solutions.
Alfen has been assisting CombiVliet since 2011 with the infrastructure for its greenhouse extensions. Up till now Alfen
has supplied the entire private medium voltage grid, including local grid connection, more than 40 transformer
stations for growing lights, two energy platforms to manage the micro grids and a smart grid solution with automatic
emergency power supply. Alfen has now been selected as supplier for the further extension of the facilities. Alfen will
also provide the technology, project management, installation, commissioning and service for the micro grid.
Richard Jongsma, Commercial Director Alfen: "The greenhouse horticulture is expanding rapidly and there is much
innovation, which leads to new challenges for the electricity grid. Alfen offers solutions in these situations."
Roy van Vliet, location manager of CombiVliet NoordVliet: "The complexity of our local energy system requires an
extremely robust and reliable energy grid. Our company motto is 'Growing Together'. This is an essential part of our
company for us. Our cooperation with Alfen is part of this philosophy: we are experts in, and passionate about
growing tomatoes, while Alfen, with its expertise in electricity grids, gives us a reliable basis for our company."
8 step extension program
CombiVliet is a family company which produces 70 million kilo tomatoes every year, and NoordVliet Middenmeer is
their biggest location. At this location CombiVliet and its partners are implementing a 8 step extension program which
was initiated in 2011. At this moment phase 6 is being implemented and about twelve hectare of greenhouse space is
added to the facilities.

US (CO): Aeroponic garden provides students with fresh greens
A new aeroponic garden in the Village Center Dining and Community Commons is the first in the nation to
provide students, staff and faculty with fresh salad greens grown on site in a high-tech greenhouse
attached to a dining hall.
The “air garden” will help the university reduce its carbon footprint, cut energy costs and eliminate the
need for harvesting, cleaning, packing and transporting food from outside farms.
The greenhouse in CU Boulder’s Village Center Dining and Community Commons occupies nearly 3,000
south-facing square feet and consists of 137 grow towers able to produce 44 plants each without soil.
“Locally grown food just tastes better,” said Farm Manager Alex Macmillan, a horticulturalist and organic
farmer who will oversee the greenhouse and its production schedule.
Macmillan and student-assistants will start by growing romaine lettuce and other vegetables in stages to
ensure a continuous supply of fresh greens.
The inaugural harvest in March produced 15 pounds of kale, 10 pounds of all-star lettuce and 10 pounds
of arugula that dining hall employees served to students, staff and faculty.
The aeroponic system at CU Boulder relies on water and “soilless media” to provide nutrients to plants,
allowing them to grow faster and produce greater yields on average.
Vertical farming allows for better space usage and efficiency, and automated operations help maintain
optimal sunlight, shade, temperature and humidity levels, creating the best year-round growing conditions.
Sensors will monitor conditions to prevent fans, lights and other equipment from running unnecessarily
when natural sunlight and other conditions are sufficient.
“I’m excited to get growing and hope this new greenhouse inspires people to be informed about where their
food comes from,” Macmillan said. “It’s not grown by someone you’ve never met on some faraway farm with
unknown farming practices. It’s me, right here, and you can literally see how I’m growing your food.”

Why data is an essential nutrient for AeroFarms crops
Urban agriculture pioneer AeroFarms eschews pesticides and herbicides.
It gets away with using considerably less water than traditional growers of the leafy
greens in which it specializes — it squeezes out almost 95 percent of what’s traditionally
used. But there’s one ingredient it can’t go without: data.
That imperative drove the well-backed startup’s partnership with information technology
giant Dell. Two big projects are underway there, within the 70,000-square-foot facility
that houses Aerofarms’ ninth indoor farming operation in Newark, New Jersey.
The first initiative uses sensors to track information at virtually every step of the growing
process — from seeding to germination to growing to harvesting and packaging — and
send it wirelessly to servers where it is closely analyzed. Aerofarms uses that information
to improve taste, texture, color, yield and nutrition metrics for its crops, according to a
case study published by the two companies.
The second project employs special cameras to track the spectral conditions of the grow
trays, and of the lighting technologies crucial for nurturing arugula, kale and mustard
greens — products that AeroFarms sells to local supermarkets under the Dream Greens
brand. (It nurtures 400 plant varieties.) If something unusual is detected, an alert is sent
to a ruggedized tablet computer. The images are also collected and analyzed.
How we organize and manage that data, it’s incredibly important.
"We have this fully connected farm that is ever becoming even more connected,"
AeroFarms co-founder CEO David Rosenberg told me Tuesday during the Techonomy
conference in New York. "That enables us to both manage the farm as well as take
information from the farm and send it to the right people to make the most of that data."
AeroFarms relies heavily on real-time information for food safety and operational
processes. It can produce a crop in just 15 days: It shrank that one day using its
information metrics, but the data is also used to influence taste and texture.
"How we organize and manage that data, it’s incredibly important," he said. "When you
have that as your lens, in looking at a business, you see problems in different ways and
solutions come and get prioritized in different ways. That’s OK."
That information will be critical for automating vertical farming processes to the point
where they can be commercialized more "meaningfully." One reason AeroFarms
dismantled its new facility’s predecessor was that it didn’t have the scale to be
automated effectively, Rosenberg said.
Often touted as the world’s largest vertical farming operation, AeroFarms employs about
130 people, including 30 formerly incarcerated individuals. The company closed a $40
million Series D funding round in October led by Meraas Holdings (from Dubai), ADM
Capital (London) and Alliance Bernstein (New York). Furniture giant Ikea was also an
investor in that round. There is a "strategic" element to that relationship, but Rosenberg
declined to elaborate.
So far, AeroFarms has raised more than $100 million. It is far from the only company
focused on urban farming technologies — even as Rosenberg was chatting with me at
the conference in Times Square, hydroponic startup Freight Farms was offering tours of
its own approach downtown in the Soho district. The Boston-based company grows
vegetables in converted shipping containers.
Since 2013, roughly $2 billion has been invested in agricultural technology (aka agtech)
across more than 700 deals, estimated Zoe Leavitt, senior retail analyst at CB Insights,
who moderated a panel about the future of food during the Techonomy conference. The
investments are coalescing around three primary areas, she suggested.
Those that promise to improve the nutritional value and sustainability of food we eat:
This would include lab-grown meat ventures such as Memphis Meats (Tyson and Cargill
are both investors), those focused on seafood (Finless Foods) and even those tackling
pet food (Wild Earth and Bond Pet). China has even negotiated a $300 million trade deal
with Israel centered on research in this area.
Those that rethink the growing and harvesting process: This includes robots such as the
technology that Abundant Robotics is developing for apple picking; predictive
agronomics information such as the data on climate-related agricultural conditions being
amassed by aWhere; or one of many irrigation management systems that are cropping
up. There are even robotic bees flying around in labs, as a recent patent filing by
Walmart suggests. Actually, scientists at Harvard have been pollinating this idea since
Those that focus on more efficient distribution methods: One of the biggest concerns
here is addressing food waste, and one example mentioned by Leavitt is Apeel
Sciences, which is working on an organic coating intended to help reduce produce
