What does 'glasshouse grown' mean?

Costa tomatoes are grown hydroponically under carefully controlled conditions in custom built glasshouses, which means that our growers can ensure that the conditions for growing and ripening are optimum at all times.

Vine ripening allows the tomatoes to develop their full sugar content so they’re more flavoursome than field tomatoes.
Wherever possible, naturally occurring insects are used to combat tomato pests without the use of chemicals.
Costa tomatoes are available all year round and their quality remains impeccable, no matter what time of the year. Our glasshouse production works in a continual cycle of growing, planting and harvesting to ensure there are always juicy
