For our farmers, harvest is the busiest, most important time of the year. To grow good food, and enough of it, farmers need to understand the science behind the harvest. Our ability to feed ourselves all hinges on the fact that plants can create their own food through the process of photosynthesis. Food fanatic Stefan Gates explores what鈥檚 going on within the process, and reveals how we can actually see photosynthesis in action with the use of some simple props. At a massive tomato greenhouse in Kent, Stefan discovers that farmers can artificially create the ideal conditions for photosynthesis to produce a bumper crop of tomatoes, even in winter, and that鈥檚 how they keep us supplied with tomatoes all year round.
