Robotics farming company Iron Ox today announced the close of a $20 million funding round. The funding will be used to open additional robotic growing facilities in California and other parts of the U.S., according to company co-founder and CEO Brandon Alexander. The funding will also be used to hire additional machine learning and robotics experts as well as growers and scientists who work with plants.
“We’re now competing on price with field farms, but we think we can do even better and take this to more people,” he said.
Iron Ox employs a 1,000-pound mobile transport system roughly the size of a car to move trays of growing vegetables and tend to plants using a robotic grasper while computer vision systems monitor the plant growth cycle. The semi-autonomous system still relies on humans for a part of its seeding, pruning, and inspection process, Alexander said, but the goal is for Iron Ox to someday be fully autonomous.
While startups like Bowery practice indoor vertical farming in urban facilities near New York and Baltimore, Iron Ox has turned its focus toward greenhouse farming since the company was founded in 2015 as a way to lower energy costs. Earlier this year, Iron Ox opened its first greenhouse, a 10,000-square foot facility in Gilroy, California, the company’s second location. Iron Ox currently provides produce to 15 Whole Foods stores in the San Francisco Bay Area.
Though Gilroy is known as the garlic capital of the world, Iron Ox does not currently grow any garlic. Instead, the company focuses on leafy green vegetables like lettuce and some herbs.
Alexander said Iron Ox’s biggest challenge is how to use data collected by sensors to train AI systems that produce higher yields at lower costs.
“I would say in agriculture as a whole it’s not just collecting data, it’s not just taking an image, but it’s actually how do you include that data into the decision making process?” Alexander said. “I would say that is the biggest challenge in ag is how do you respond to these each individual plants and the variety and all these little variables.”
The $20 million funding round was led by Pathbreak Ventures with participation from Crosslink Capital, Amplify Partners, Eniac Ventures, R7 Partners, Tuesday Ventures, and At One Ventures. Iron Ox is based in San Carlos, California. The company currently has 30 employees and has raised $45 million to date.
Field farming today is still the most efficient way to grow produce. However, concern about shrinking field yields and instability due to climate change has spurred interest in indoor farming. In 2018, international teams from companies like Microsoft and Tencent competed against each other to find out who could grow the highest yield of cucumbers inside a greenhouse using AI and automation. (Spoiler: The Microsoft team won.)
In other AI and agriculture news, last month the startup iFarm raised $4 million for its AI-driven urban farming solution, and in June the startup Burro began rolling out its autonomous farm robot in southern California to assist in grape harvesting.

What Is Hydroponic Farming?
It is the process of growing crops with nutrient-rich water kept in contact with the plant roots without using soil. This process is touted to significantly reduce the risk of wastage and pollution that can harm the produce and cause diseases, making it popular to health-conscious consumers
Kemkar wants to make a difference through urban farming by introducing the technique of hydroponic farming to all so that they have access to grow their own vegetables at home.

The science of urban farming has become hugely popular in recent times and hydroponics is leading the way in this green revolution. Jui Kemkar, a passionate young entrepreneur with a quest to make a difference through urban farming co-founded Waves Enterprises with a vision to introduce the technique of hydroponic farming to all, such that they have access to grow their own vegetables at home.
“From residential balcony gardening, community farming, or indoor/outdoor commercial farming, hydroponic farming methods prove to be beneficial for all. Residential enthusiasts of hydroponics can grow herbs, green leafy vegetables, tomatoes, cumbers, and even small plants or flowers in the comfort of their own homes,” explains Jui.
Jui’s impressive repertoire of work comprises humanitarian work in rural, urban farming projects in India and empowerment of women. It was when she moved from India to Dubai that she chose to promote hydroponic farming in order that healthy food supplies can either be grown by families in their own homes or produced by companies and supplied at affordable rates in the UAE.
Jui talks about her conviction that the future of farming lies in hydroponics.
What is hydroponic farming?
It is the process of growing crops with nutrient-rich water kept in contact with the plant roots without using soil. This process is touted to significantly reduce the risk of wastage and pollution that can harm the produce and cause diseases, making it popular to health-conscious consumers. This method saves up to 70 percent of water while allowing for a longer growing season and avoiding harmful chemicals.

How suitable is this for Middle East consumers?
The extreme climatic conditions and limited agricultural land availability in the Middle East makes hydroponic farming an excellent agro-solution as it increases farming capability. The absence of soil in the growing process makes it conducive for this method of growth to be used in an indoor or outdoor setting.
Can you explain the actual process behind this?
Plant growth happens through a combination of water, sunlight, carbon dioxide, and mineral nutrients. In traditional farming, these nutrients are derived from the soil. Through photosynthesis, plants transform light energy into chemical energy to form sugars that allow them to grow and sustain themselves. This is the basic premise behind hydroponics where all the elements required for plant growth are the same as with traditional soil-based gardening but only taking away the soil requirements, hence making it convenient to perform the farming process anywhere within a controlled environment.
What are the advantages of this kind of farming?
For one, plants can grow both indoor and outdoor and there is growth observed throughout the year. There is complete control over the nutrient balance with a proven technology that ensures high yield. Research shows that growth is faster with hydroponics and 70 percent less water is consumed in the farming process. No harmful contents enter the plant, as no soil or fertilizer or other harmful chemicals are used. The overall economy of a nation will benefit by promoting local farming and reducing the import of vegetables from other countries.
How affordable is this type of farming?
Residential setups are affordable and can be customized to individual budgets; however, commercial farms can be expensive depending on the extent of growth required. But despite the heavy investments for commercial set-ups, profits of up to 60 percent or more are visible in a short period of time. Profits will vary and depend largely on the type of crop cultivated. For example, due to low operational costs, green leafy vegetables yield more profits.
What kind of environment protection does this offer?
As global warming becomes a bigger issue for the world, there is a constant need for better ways to cut down on CO2 emissions to help the environment thrive. Perhaps one of the greatest ways countries can cut back on harmful greenhouse gasses is through examining how they produce and distribute their food supply. Hydroponic growing has numerous possibilities to produce larger, better-tasting vegetables. This method of growth uses less land, 70 percent less water, and minimum to no use of pesticides or herbicides.
Due to controlled growing environment, growth is possible in all types of climatic conditions. Dry and arid climates are not conducive to the growth of berries, bananas, and citrus fruits; however, one country was able to successfully adopt the hydroponic growing process on a large scale. The produce was grown in 40ft large containers and transported to consumer markets for sale.
What is the future of hydroponic farming?
Hydroponics is the fastest growing sector of agriculture, and it could very well dominate food production in the future. As population increases and agricultural land declines due to poor land management, people will turn to new technologies like hydroponics and vertical farming to create additional channels of crop production.
First Indoor Basil Harvested In Delphy Improvement Center
Meulendijks has been working on the development of practical cultivation knowledge for Vertical Farms. Growth factors such as climate, light and irrigation can easily be varied in the test chambers.
The first batch of indoor-grown basil was harvested at the Delphy Improvement Centre. Since May, Lisanne Meulendijks has been working on the development of practical cultivation knowledge for Vertical Farms. Growth factors such as climate, light and irrigation can easily be varied in the test chambers.
Because of this flexibility, experiments can be conducted to see how cultivation in a Vertical Farm can be optimized. The focus is on analyzing the plant’s growth process. In a Vertical Farm, the plant influences its own growing environment relatively strongly which creates a microclimate around the crop that deviates from the controlled climate in the chamber.

Cultivation factors
The degree of exchange between these climates depends on the design of the Vertical Farm. In order to fully utilize the potential of a Vertical Farm, optimization of the growth recipes should be based on this principle, because it is ultimately the microclimate that controls the growth of the plant.
By approaching the research from this angle and looking at the effect of the different cultivation factors on the plant, it is possible to formulate growing advice that is specific for different Vertical Farming facilities.
Light intensity
The first experiment looked at the effect of increasing light intensity on the growth of basil, in combination with testing different types of substrate. By using sensors on and around the plant, the growth was closely monitored and could be linked to the microclimate between the crop and the macro climate in the cell. This led to interesting and tasty first results, says Lisanne.
Investigating business questions
The graph shows the relation between increasing light intensity and annual production: the more light, the steeper the curve, the faster the plants growth. The fact that the plant grows faster with more light is of course nothing new.
What makes these results interesting is that each growth curve can be expressed in a formula and the error margin around the curves is small, Lisanne explains. This is because the growing conditions within a Vertical Farm are completely under control. Cultivation practices can then be optimized using the formulas behind these kind of curves.
It becomes possible to formulate answers to questions such as: “How does an investment in extra light affect my yield? How many days after germination is best to harvest to maximize my yield?”
These are important business aspects for production. "Through our application-oriented research, we develop knowledge that responds to these kinds of practical questions."
Fresh weight of the basil plotted as a function of light intensity and days after germination.
This experiment is part of the Fieldlab Vertical Farming South Holland project. This project has in part been made possible by the European Fund for Regional Development of the European Union and a contribution from the Province of South Holland.
