What is indoor farming?


Indoor farming truly has the potential to revolutionize the food industry as we know it today. The simplest way to describe indoor farming is literally farming done inside of a building. It does not require large equipment like tractors, and often is more sustainable and uses way less resources like water in comparison to more traditional ways of farming.

Indoor farming can be divided into three different pillars: vertical farming, hydroponic farming and Controlled Environment Agriculture (CEA). The first one, vertical farming, refers to food grown on top of each other going upwards. The second one, hydroponic farming, happens when you grow plants without the use of soil. Controlled Environment Agriculture means that the farmers can control every aspect of the environment that the plants are grown in, and it encompasses vertical and hydroponic farming as well.

What exactly can be grown indoors?

While grains are still grown outdoors in fields, there are many vegetables and fruits that can be grown indoors very easily. These include: cucumbers, herbs, lettuce, peppers, strawberries, tomatoes, summer squash, eggplant, cantaloupe, microgreens & sprouts, spinach, and mushrooms. Although there is lots of other produce that has been hard to grow indoors so far, the technology is growing at a rapid speed to allow production of virtually anything.

When it comes to advantages of indoor farming, and especially vertical farming, an article by Bowery Farming puts it straight: decreased land usage, urban agriculture, year round yields, decreased transportation, healthier and more abundant crops and lastly: more sustainable practices. United Nations estimates that the world’s population will reach 9.8 billion by 2050. To feed this ever-growing amount of people, there is a greater need for practices that are not only more sustainable but will ensure food security. This is where Indoor Farming will help!

To showcase the accelerating change in the Agricultural sector, we decided to spotlight six different Indoor Farming startups revolutionizing the market. We provide a global overview, but our main focus was European AgTech startups, spotlighting the innovation happening in Europe.

According to the company, the initial footprint of the indoor vertical farm can yield over 1,000 kilograms of leafy vegetables per day, and will be entirely powered by renewable energy.

As said by Valentinas Civinskas, founder and CEO of Leafood: “We need to innovate and find new ways to farm healthy, sustainable food, year-round, locally and indoors. By developing a network of high-tech, indoor vertical farms, we are trying to solve this problem of food security for the Baltic region.”

The company uses beer and bread waste to grow their mushrooms, and they deliver it by bike within Brussels. to attract people to their mission, Eclo runs public tours of their facilities to put forward what city farming is about, by the end of which each visitor gets 400 grams of Brussels Mushrooms!

  1. Future Crops (Netherlands)indoor farming - future crops

Future Crops is an Indoor Vertical CEA Farming startup from Poeldijk, The Netherlands. The company claims to have the first soil-based vertical farm in Europe, with over 8,000 square meters of production area. Future Crops utilizes solar energy to power their production and recycles the water used for production. Their farm is located close to the Port of Rotterdam, where one can find all the links in agri-food supply chain.  The company raised their latest funding in March2022, and is actively hiring.

As said by the co-founder and CEO of Future Crops Gary Grinspan: “We are able to grow tremendous amounts of high-value food on a much smaller stretch of land—approximately 5% of the land required for conventional agriculture. And having no reliance on seasonality amplifies growing cycles tenfold. This means we can grow more faster while concurrently cutting the food mileage. Our produce also has a naturally longer shelf-life which cuts food waste and eliminates ecotoxicity to people and the earth since no pesticides or harmful chemicals are required. The Future Crops system also addresses the downside of the controlled indoor methods of growing crops: high energy consumption due to crops being unable to soak up natural sunlight.”
