Outdoors it’s the bleak midwinter. We’re smack bang in the midst of among the nation’s finest agricultural land.
However contained in the cavernous warehouse the place we have come, you would not have a clue about any of that: there is no such thing as a daylight; it feels prefer it could possibly be any time of the day, any season of the yr.
We’re at Fischer Farms – Europe’s largest vertical farm.
The entire level of a vertical farm is to create an setting the place you possibly can develop vegetation, stacked on high of one another (therefore: vertical) in excessive density. The concept being which you could develop your salads or peas someplace near the cities the place they’re consumed moderately than a whole bunch of miles away. Location shouldn’t be alleged to matter.
Farm 2 of Fischer Farms
So the truth that this explicit one is to be discovered amid the fields a number of miles exterior Norwich is considerably irrelevant. It could possibly be wherever. Certainly, not like most farms, that are typically named after the household that owns them or a neighborhood landmark, this one is solely known as “Farm 2”. “Farm 1” is to be present in Staffordshire, in case you have been questioning.
Farm boss’s dizzying ambition
These futuristic farm models are the brainwave of Tristan Fischer, a serial entrepreneur who has spent a lot of his profession engaged on renewable vitality in its numerous guises. His ambition now’s dizzying: to have the ability to develop not simply basil and chives in a farm like this however to develop different, trickier and extra aggressive crops too – from strawberries to wheat and rice.
Solely then, he says, can vertical farming stand an opportunity of actually altering the world.
The concept behind vertical farming itself is greater than a century outdated. Again in 1915, American geologist Gilbert Ellis Bailey described the way it could possibly be achieved in concept. In concept, one ought to be capable to develop vegetation hydroponically – in different phrases with a mineral substrate as a substitute of soil – in a managed setting and thereby enhance the yield dramatically.
In a single sense that is what’s already being achieved in greenhouses throughout a lot of Northern Europe and the US, the place tomatoes and different warm-weather-loving greens are grown in temperature-controlled environments. Nonetheless, whereas most of those greenhouses nonetheless depend upon pure gentle (if typically bolstered by electrical bulbs) the purpose behind vertical farming was that by controlling the quantity of sunshine, one may develop roughly every part, any time of the yr. And by stacking the crops collectively one may yield much more crops in every acre of land one was utilizing.

Take a look at a long-term chart of agricultural yields on this nation and also you begin to see why this would possibly matter. The amount of crops we develop in every acre of land jumped dramatically within the second half of the twentieth century – a consequence in a part of liberal use of synthetic fertiliser and in a part of new applied sciences and techniques. However that productiveness price began to tail off in direction of the tip of the century.
‘Altering the equation’
Vertical farming guarantees, if it may well make the numbers add up, to alter the equation, dramatically growing agricultural productiveness within the coming many years. The query is whether or not the know-how is there but.
And relating to the know-how, one factor has actually modified. These early vertical farms (the primary makes an attempt really date again to the Fifties) all had an enormous downside: the bulbs. Incandescent bulbs have been each too sizzling and too vitality intensive to work in these environments. However the newest technology of LED bulbs are each cool and low cost, and it is these bulbs you want (in huge numbers) if you are going to make vertical farming work.

The farm is rising basil however the ambition is to develop far more than easy herbs
Right here at Farm 2, you encounter row after row of trays, every stacked on high of one another, every carrying more and more leafy basil vegetation. They sit beneath 1000’s of little LED bulbs that are tuned to exactly the proper spectral frequency to encourage the plant to develop quickly.
Mr Fischer says: “We’re on this downward value curve on LEDs. After which when you consider different principal inputs, vitality – renewable vitality – is continually coming down as nicely.
“So you consider all the massive drivers of vertical farming, they are going down, whereas in comparison with full-grown crops, every part’s going up – the fertilisers, rents, water is turning into dearer too.”
Simply over a month after the basil was seeded, it’s now totally grown and trays of the crop are moved to the harvesting machine
This farm – which presently sells to restaurant chains moderately than direct to customers – is now cost-competitive with the basil shipped (or extra typically flown) in from the Mediterranean and North Africa. The carbon footprint is significantly decrease too.
“And our long-term objective is that we are able to get lots cheaper,” says Mr Fischer. “For those who take a look at Farm 1, we spent about £2.5m on lights in 2018. Quick ahead to Farm 2; it is seven and a half instances larger and in these three years the lights have been successfully half the value. We’re additionally in all probability utilizing 60 to 70 p.c much less energy.”
Farm boss Tristan Fischer speaks to Sky’s Ed Conway
It may appear odd to listen to a farmer discuss a lot about vitality and relatively much less concerning the sorts of issues one associates with farmers – the soil or tractors or the climate – however vertical farming is largely an vitality enterprise. If vitality costs are low sufficient, it makes the crops right here significantly cheaper.
However right here within the UK, with energy prices increased than wherever else within the developed world, the prospects for this enterprise are extra challenged than elsewhere. Nonetheless, Mr Fischer’s goal is to show the enterprise case right here earlier than constructing larger models elsewhere, in nations with less expensive energy.
In a lot the identical manner as Dutch growers got here to dominate these greenhouses, he thinks the UK has an opportunity of dominating this new agricultural sector.
