How do you grow food during space missions to places like Mars? That is the key question researchers at the University of Guelph in Ontario, Canada, are trying to answer. And the Grodan Group, makers of sustainable, stonewool-based substrate solutions for the horticultural industry, is playing a significant role in this high-tech research project by supplying the substrate that the plants being studied in Canada are being grown in. The first manned mission to Mars is scheduled to take place in 2035 and will take about two and a half years. Taking along food supplies for the entire journey is impossible—that would amount to more than 3,300 pounds per person. The solution lies in growing their own food. Grodan stonewool is a light and compact growth medium that yields maximum results with the use of minimal resources and is suitable for use in closed cultivation systems, where water is recirculated and reused.
