This hydroponic farm features 'magic' capillary wick feeding of special liquid nutrients to big biodome gardens where kids can grow their own sandwich fillings — without soil. It offers "leading-edge science for feeding populations where soil is poisoned or non-existent. We supply lab equipment and chemicals for kids to make their own liquid nutrients [and] purify and balance pH. Twin tanks and twin drainage reservoirs means two separate farms can compare different nutrients at same time," Agatha Pan, international sales manager for Tree Toys Corp., told TDmonthly. Launch date: June 2009.
