Hydroponic farming:

From seed to harvest in 30 days

Hydroponic farming makes it possible to grow fresh greens without soil, using only water, nutrients, and light. When combined with vertical farming in Grönska’s cabinets, it becomes a compact, efficient, and sustainable way to produce food right where it’s consumed.

The result? Up to 90% less water use, no pesticides, shorter transport distances, and harvests that are ready all year round. Schools, restaurants, and workplaces can serve herbs and salads that are fresher, tastier, and better for the planet – grown directly on site.

FAQ Hydroponic Farming

  • Hydroponics is a method of growing plants without traditional soil. Instead, plants grow in water enriched with nutrients, under controlled light and climate conditions.

    Grönska use coconut fibers instead of soil for optimal taste, sustainability and longevity.

  • Vertical farming means growing plants in stacked layers, making it possible to produce a high yield in a very small space. This means you can grow crops indoor all year round, also in colder climates.

    In Grönska’s cabinets, hydroponics and vertical farming are combined for maximum efficiency.

  • You can grow a wide variety of herbs, leafy greens, and edible flowers. Basil, coriander, lettuce, and crisp sallat are among the most popular.

    We are constantly adding new crops to grow in our cabinets.

  • Most herbs and greens are ready within 30–50 days, depending on the variety. Basil and coriander can be harvested in as little as 30 days.

  • No, we use a clean growing substrate made of coconut fibres, a waste product that is safe to bring into kitchens.

  • Yes. Hydroponically grown food is completely safe. In fact, since no soil or pesticides are used, it is often cleaner and fresher than traditional produce.

  • No. The system is fully automated and controlled via the smartphone APP. The cabinet controls water, light, and nutrients for you. You just insert the pods with the pre-planted seeds and harvest when ready.

  • Hydroponic vertical farming uses up to 90% less water, no pesticides, and drastically reduces transport distances since food is grown on site.

    You get fresher taste, less food waste, and a more sustainable footprint — while also engaging people with visible, local food production.

  • Our cabinets are designed to be placed indoor where its not too cold and in direct sunlight. All cabinets need electricity and, for some models, a water connection.

    The cabinets are controlled via WiFi or a 4G connection.

  • Grönska’s vertical hydroponic cabinets are built for simplicity, efficiency, and design. They don’t just grow fresh herbs and salads — they look good in any environment, from restaurants to schools and offices. Our systems leverage real-time data to continuously optimize the growing process, adjusting light, water, and nutrients to achieve the best possible harvest, taste, and energy efficiency.

    With Grönska, you get a solution that combines cutting-edge technology, sustainability, and Scandinavian design into one fully automated growth cabinet.
