I've seen lots of these odd constructions...
![]() |
... from the air.
They're greenhouses; a common sight as you fly over agricultural lands.
These images are from: 36.699632, 118.730094 – China Weifang ; 43.547962, 16.293624 – Split, Croatia; 36.878222, -2.370747 – Almería, Spain ; 35.420553, -80.780018 – Huntersville, North Carolina, US
Sometimes they cover an enormous area of land, as in Weifang, China where greenhouses spread over more than 820 square kilometers. (Weifang is a prefecture-level city in Shandong Province in northeastern China.)
You'll also see lots of greenhouses from the air in Europe and the US. Notably in southern Spain, around Almería. Where, by some estimates, the greenhouses cover more than 40,000 hectares (150 square miles)—nearly all of Campo de Dalías.
Naturally, my curiosity is piqued by seeing such giant constructions, and it reminded me that not so long ago, there was a boom in highly efficient greenhouses that were going to be powered by AI, robots, and high-tech lighting.
These lead me to a few curious questions for you to ponder. Can you find the answers? If so, what did you do to discover the results?
1. How long have greenhouses been around? If greenhouses date to around Roman times (as I've heard), what were the greenhouses made of?
2. What is growing under all of those greenhouses? What's grown in Weifang that needs SO many greenhouses?
3. Those robotic greenhouses... how well are they doing? Has there been a boom in robotic and/or vertical greenhouses in the past 10 years? Is it a growth industry?
Let us know what you discover! And just as importantly, tell us how you found the answers.
Forward!
Keep searching.

ReplyDelete"AI Overview
The image shows the "Mar de Plástico" (Sea of Plastic), which is the world's largest concentration of greenhouses, located in the province of Almería, Spain.
The greenhouses cover more than 40,000 hectares (150 square miles) and are visible from space.
They produce between 2.5 million and 3.5 million tons of fruits and vegetables annually, making the region a major exporter to Europe.
The use of plastic greenhouses, along with access to groundwater, has allowed this arid region to become a highly productive agricultural area.
A study has suggested that the white plastic of the greenhouses reflects sunlight and has a local cooling effect on the climate of Almería. "

"AI Overview
Roman greenhouses, or specularium, were built with frames covered in transparent materials like sheets of mica (a mineral) or lapis specularis (a translucent variety of gypsum, or selenite), though oiled cloth was also used for additional warmth. These frames protected plants growing in wheeled beds that could be moved into the sun and sheltered at night to maintain a warm environment, effectively creating a controlled growing season for emperor Tiberius.
Key Materials:
Mica:
A translucent mineral composed of layered sheets that could be used to cover frames.
Lapis Specularis (Selenite):
A naturally clear, crystalline variety of gypsum that splits into thin, transparent sheets similar to mica.
Oiled Cloth:
Used as an alternative or supplement to the transparent stone to provide additional insulation and protection for the plants. "

pt.2 "AI Overview
ReplyDeleteSeveral robotic greenhouse companies claim high efficiency, but the most efficient operational system depends on the metric used, such as water usage, land use, or labor reduction. Two notable contenders are Hippo Harvest and Canopii, both launched in late 2024 and built with efficiency as a core principle.
Hippo Harvest
This Pescadero, California-based company adapts off-the-shelf warehouse robots for greenhouse use, an efficient strategy that reduces the high cost of custom-designed systems.
Water savings: Hippo Harvest reports a 92% reduction in water usage compared to traditional farming.
Operational model: Trays of crops are moved by robots, which also deliver precise amounts of water and fertilizer, resulting in minimal waste.
Data-driven efficiency: The system acts as a real-time experiment, with machine learning and sensors constantly collecting data on plant health. This allows for continuous optimization of growing conditions.
Canopii
Located in Hubbard, Oregon, Canopii operates a 2,500-square-foot autonomous greenhouse that automates most of the crop cycle.
Human-free crop handling: Robotics and machine vision handle planting, transplanting, sorting, and harvesting of leafy greens and herbs with minimal human intervention.
Space optimization: Co-founder David Ashton notes that the verticality of the greenhouse maximizes production within a small footprint.
Reduced footprint: The system reduces the environmental impact of farming by minimizing the use of resources.
Other notable systems
Four Growers: This company specializes in robotic harvesting for crops like tomatoes. Their system, launched in 2023, is focused on efficiency in the labor-intensive harvesting process for select crops.
Iron Ox: A pioneer in autonomous farming, Iron Ox has developed AI-enabled systems and mobile robots that automate much of the growing cycle, allowing for fresher, more consistent produce.
Older, large-scale facilities: Operations like the AppHarvest facility in Kentucky, built in 2020, also achieved impressive efficiency metrics for their time, such as using 90% less water than open-field farms.
pt. 3 Cali:

cool, informative video - good to see the different approaches being used - thanks for finding & sharing.
DeleteGemini AI Overview:
"The Netherlands is a leading global producer of commercially bred bumblebees, primarily for greenhouse pollination. Instead of importing most of their managed colonies, Dutch and other European growers get their bees from large, specialized insect breeding companies.
Commercial production
Dutch companies: A key player is the Dutch company Koppert Biological Systems, whose Natupol brand bumblebees are used by growers worldwide.
European pioneers: The commercial bumblebee industry was pioneered in the late 1980s by Belgian companies like Biobest and expanded quickly to the Netherlands. This development enabled the year-round production of bumblebees for crops such as greenhouse tomatoes.
Mass breeding: These companies mass-produce bumblebee hives in controlled environments that mimic the species' natural life cycle. The colonies are inspected and certified to be disease-free before being sold to growers.
Buff-tailed bumblebees: The most widely used species for commercial pollination in Europe is the buff-tailed bumblebee (Bombus terrestris) due to its large size and reliable breeding.
Wild bumblebee populations
The Netherlands also has native, wild bumblebee populations, which are separate from commercially bred colonies.
Native species: The white-tailed bumblebee (Bombus lucorum complex) is common, along with others like the red-tailed bumblebee (B. lapidarius) and the common carder bee (B. pascuorum).
Conservation efforts: Dutch ecological programs, such as the Honey Highway initiative, focus on supporting native pollinator populations by creating wildflower habitats along roadways and railways.
Overlooked migration: Research shows that wild bumblebees in the Netherlands also participate in large-scale migrations, with mass movements of queens observed at coastal sites. However, this natural phenomenon is largely unrelated to the commercially supplied bees used in agriculture. "

I feel I'm cheating by not (at least initially) using Google. But it also shows how search is changing - and realistically, if you google something now you are wasting time. Yes - I'll use Google to verify results, but for research questions like this, I start with AI and often ChatGPT. So I'll link my AI search and then how I confirmed with other sites.
ReplyDelete1) I copied the whole question to get https://chatgpt.com/share/68d54860-f388-8001-8712-4d9a430007c4. This mentions Roman greenhouses called specularia using mica so a search for gave confirming sites: https://www.academia.edu/105204999/History_of_Controlled_Environment_Horticulture_Ancient_Origins (also on ResearchGate) - from HortScience 57(2):236-238, 1922 - and some images of Roman greenhouses. There's also https://www.greenhousegrowing.co.uk/greenhouse-designs/history-greenhouse-design/ and other sites e.g. https://agriplasticscommunity.com/greenhouse-where-in-the-world-and-how-was-the-first-built/
2) https://chatgpt.com/share/68d55330-28d8-8001-b004-84c991b26f96 gave a great site from NASA that shows the Weifang area in 1987 and how it changed in 2024. https://earthobservatory.nasa.gov/images/152874/a-greenhouse-boom-in-china. This includes "In this part of China, fruits and vegetables are generally grown in the greenhouses. Cucumbers, eggplants, and tomatoes provide off-season vegetables to the whole country...Increasingly, farmers in Weifang are also planting high-value fruits, such as strawberries, grapes, kiwi, and dragon fruit. Farmers use plastic greenhouses because they are an effective and relatively inexpensive way to increase yields. They can be used to extend the growing season and exert control over temperature and lighting conditions. Innovations such as drip irrigation, the use of artificial soil, and hydroponics have added to the popularity of greenhouse cultivation." The article continues to say domestic demand increased sixfold between 1990 and 2020. There's also mention of problems with the growth in greenhouses globally at https://e360.yale.edu/features/greenhouses-cooling "A sperm whale offshore of Almeria washed up dead in 2013 with 37 pounds of plastic sheeting from greenhouses in its gut."
Answer 3 as a separate comment.
3) https://chatgpt.com/share/68d552f6-d450-8001-8203-0621bace0203 "There is a growing trend toward automation, robotics, AI and sensor-driven control in greenhouses and other controlled environment agriculture (CEA) systems (including vertical farms). Over the last decade, the sector has attracted more investment, research, and deployment."
ReplyDelete"The current consensus is:
• Vertical farming / vertical greenhouses are a high-growth niche segment (not likely to replace open-field or conventional greenhouse agriculture broadly, at least in the near term), but as technology costs fall (lighting, sensors, energy) and as control systems improve, its footprint is expected to expand.
• The future is likely to be a hybrid: some blend of greenhouse + stacked systems + semi-automated growth systems — not a one-size-fits-all.
• In regions with high land costs, high logistics costs, or energy subsidies (or cheap energy), vertical systems are more competitive.
• Attention is shifting to reducing energy demand (more efficient LEDs, better thermal insulation, integration with renewable energy) to improve economics.
• Smaller-scale, modular, urban vertical farms (closer to end consumers) may find more success than the very large “factory farms” in many markets.
So yes: it is a growth industry (or sub-industry) with strong tailwinds, but it’s still an emerging sector rather than a mature, dominant paradigm."
ChatGPT gave lots of sources and research reports e.g. https://www.sciencedirect.com/science/article/pii/S0168169924001418 (Robotics); https://ers.usda.gov/sites/default/files/_laserfiche/publications/108221/EIB-264.pdf (more on vertical farming than robotics); https://www.frontiersin.org/journals/science/articles/10.3389/fsci.2024.1491748 (Vertical farming again); https://www.researchgate.net/publication/360848776_Greenhouse_Robots_Ultimate_Solutions_to_Improve_Automation_in_Protected_Cropping_Systems-A_Review (Robotics);
Overall the conclusions seem sound but to really say it's a growth industry and to invest is a different question. I'd need to look at the sources in more detail but as a broad brush answer, i'm happy with it.
good examples of how search use is changing/evolving with AI... it may be a small change, but I find myself using copy & paste and voice search more than I have in the past... slowly teaching this old dog new tricks... requires checking out new AIs and versions and adjusting.
