Feeding future urban populations - Introducing the vertical farm
Vertical farms are a very promising and sustainable solution to the growing needs for healthy, local foods in (over)populated urban areas. What’s more, at Grodan, we believe vertical farms will play an indispensable role in our future global food production.
How It Started
Producing more with less is in our roots. Since we invented hydroponic stone wool growing in 1969 we have continuously evolved the Grodan approach to sustainable growing. Our first customers started growing hydroponically to avoid disinfection of the soil which was done with methyl bromide, a heavy toxic chemical. Our growing media enabled them to provide the plants with water and fertilizer much more precisely and efficiently.
By doing so the yield per square meter further increased, while at the same time saving water, fertiliser and subsequently saving on costs. Grodan can be seen as one of the Founding Fathers of Precision Growing for the horticulture industry. Today,growers make use of a wide range of innovative products for the entire growing cycle from the start of propagation till harvesting.
Sustainability is in our genes. From the moment we’ve invented stone wool growing we have been facilitating an efficient way of producing food to keep people healthy, with a positive impact on the planet by minimising the use of resources, whilst at the same time helping growers optimise their profit to sustain their businesses in the future.
