We have just harvested our first crop from our growing tower. In year 6, we’ve been growing salad leaves hydroponically. That means that the plants do not grow in soil.  Instead, they have been growing in a special tower where they get all the minerals they need from a chemical, that is poured into a big water tank and is then pumped around the tower to reach their roots. The plants were fresh and delicious and had virtually no food miles. We hope that a different class will grow the next harvest.
