Project Spotlight: Stockbridge Technology Centre (STC)

We built a state-of-the-art commercial scale vertical farm for the research and technology transfer centre at Stockbridge in Yorkshire. The unit is a 4 multilevel ebb and flood system in two rooms giving a total of over 200m2 of growing area.

The entire system is operated by the very latest Priva environmental computer with a multitude of sensors mapping and controlling the whole system. As well as this, the system has a fully recirculating two tank hydroponic feed and irrigation unit.


Project Spotlight: Liberty Produce

We designed and built a three-container growing unit, specifically for research and trials. The state-of-the-art growing facility contains three individual growing systems:

  • NFT
  • Ebb and Flood
  • Deep water

This project is clear evidence of our wealth of systems experience!


Creating farms for the future

Our vertical farming units are designed and built in our NEW HQ in Yorkshire. Our in-house design and engineering team work closely with growers to design the farm and size out irrigation, HVAC, hydroponic systems, lighting, and controls.

Our grower's perfect vertical farming solution is then installed by us. Plus, we provide important post-installation training.

Let us help you create your very own farm for the future!

NEW signage for our NEW office!

As part of our continued growth, we are opening an office – and as such, that means new signage. We can’t wait to welcome visitors to our GrowStack HQ! If you look closely at the door reflection, you will spot one of our Founders Chris Nelson who is playing the harmonica… we have many talents

We are delighted to announce our recent collaboration with LettUs Grow, Digital Farming, and Farm Urban to bring the important benefits of controlled environment agriculture to Welsh communities. This is one of the widest collaborations between leading agritech providers in the UK to date, with a focus on delivering vertical farms across different locations in Wales as part of a social-impact and community focused project called Crop Cycle - Cylch Cnwd.

Full project details coming soon…  


Why should you embrace growing locally?

Locally grown fruit and vegetables produced in the community where it is consumed has many benefits:

  • Reduces transport costs
  • Environmentally friendly
  • Reliable year-round crop production
  • Lower lead times

Our hydroponic systems will empower you to grow local and fresh produce on your doorstep.


Project Spotlight: Ikea’s Space10 innovation lab

GrowStack worked alongside IKEA's innovation lab SPACE10 to create a pop-up farm to grow tiny greens that were used to prepare 2,000 nutritional salads for London Design Festival.

These crops were grown hydroponically in six of our GrowStack systems, meaning they were set into water filled with nutrients, rather than soil, fitted with Valoya L28 AP673L spectrum for vegetative growth overhead.

This project showcases how our system can help grow tasty, nutritious, and local food that is much more accessible and affordable for communities.

Top tips on how to grow delicious hydroponic cucumbers

They are easy to grow, they produce exceptional high yield and low insect pest damage! Here are some tips to get you started:

  • Best temperature: 70-80 degrees
  • Spacing: Cucumber patches need to be 6-8 inches apart
  • Light: Aim for 12-14 hours of light each day – that could be a LED source or natural sunlight
  • pH level: 5.0 – 6.0

    Do you need a bespoke growing unit to grow your cucumbers? Contact us today.

Forget everything you were taught in biology – plants actually don't need sunlight to grow.

Vertical farmers typically opt for LED tubes to illuminate their crops as these can be placed close to the canopy, produce optimal light intensity and minimal heat.

Our Valoya LED tubes help increase floor space and production as they are designed to be stacked close to the crops, 25cm away, if not closer, to allow you to vertically stack your product and LED lighting system. Meaning spaces such as car parks and warehouses are all commercially viable spaces.

Each LED chip inside the tube contains the entire light spectrum meaning there is absolute light uniformity at all distances of the luminaire and the plant, enabling uniform growth of plants at all stages including the most delicate one, seedling.

Let us explain what a Hydroponic growing system is...

Hydroponics is growing produce without the need for soil. Plants are placed in a growing medium and nutrients are provided directly to the roots through water, rather than being absorbed out of the soil.

Each variable is closely controlled in hydroponic farming – resulting in healthier produce and enabling you to produce much greater yields.

Another great benefit is the intensity at which some crops can grow in hydroponics. The plants don’t need to grow huge root systems to get the nutrients they need so they can focus on growing their big juicy fruits or leafy greens, which means they can grow a lot faster than normal. If you combine this with LED light you can reduce the time it takes to grow crops by up to a third! This method is especially effective with leafy green plants like lettuce or basil.

Using our system you can grow: Spinach, kale, mint, tomatoes, strawberries and much more…

GrowStack are experts in building vertical farms. Work with our team today to build the farms of the future.

Summer tomatoes

Hidden 33 meters below the streets of Clapham in a former air-raid shelter you will find Growing Underground!

The system was built to a bespoke specification to fit the tunnels where height and width restrictions were some of the many challenges. Valoya LED tubes were used to increase floor space and production as the LEDs allow the bench systems to be designed close together.

Today, their produce is used by top chefs and can be found in many major supermarkets, such as Waitrose and M&S. Produce ranges from radish, garlic chives, fennel to pea shoots, rocket, wasabi mustard, and red basil

Due to a controlled environment, each tiny leaf tastes as amazing as the last. The greens are unaffected by the weather and seasonal changes, and thanks to their prime location it drastically reduces the food miles for retailers and consumers.

Farms are growing beneath our cities and towns.

Indoor farms growing fruits and vegetables in these space-efficient, climate-controlled environments have started popping up all over the world from Japan to London.

But in already over-developed cities, where can you put a farm? It can feel like there is nowhere left to build. But there is a lot of room in cities if you know where to look.

GrowStack built a bespoke system for GROWING UNDERGROUND LTD which is hidden 33 metres below London the farm utilises abandoned air-raid shelters that were built in world war two.
One of the tunnels hosts trays of sprouting herbs utilising 550sqm of the air raid tunnels to produce about 20,000kg of greens every year!

There is plenty of space in our cities for farms – we just need to think differently…

The Future Farming Hub facility offers testing, research development, and integration capabilities in a total controlled environment agriculture (TCEA) commercial demonstrator system.

The Future Farming Hub is the home of the next generation of AgTech and modern farming knowledge and is based at the prestigious James Hutton Institute. This state of the art fully contained and controlled vertical farming R&D facility contains 3 growing systems; NFT, Ebb & Flood, and Deep Water Culture to allow the FFH to provide industry-leading vertical farming knowledge and expertise from the vertical farming school. The FFH enables the development of next-generation food production technologies and knowledge sharing that will reduce barriers to adoption whilst working towards a sustainable and productive, net-zero emissions future.


Winter outside, harvest-season inside with Shipping Containers

Shipping Containers re-purposed for mini farms or grow rooms are secure, moveable and most importantly not affected by the weather or pests, with the added bonus that this ultimately reduces food mileage.

GrowStack’s shipping container farms can have 1 – 5 tiers of growing medium which is fed by an enclosed water system and nutrient tank. Also included is a climate control system, LED grow lighting and pH dosing systems along with monitoring systems that can be checked remotely.

If you want to set up your own farm inside a used shipping container, we’ve got you covered.


Stockbridge Technology Centre (STC) is raising the roof to light up the future

STC has opened a state of the art research facility to examine the effects of different LED lights on fresh produce and long season crops.

The multi-tier unit is an Ebb & Flood system with GE balanced LED’s for optimum plant growth.

Spanning across two rooms the vertical farming system provides 200m2 of growing area, providing a springboard to closed cultivation and city farming by allowing growers to test crops and ideas before embarking on large scale investments and builds.
