Aiva dreams of fresh veggies—even in the middle of winter! With help from Green Squad pals Lisa and Éric, she visits a super cool rooftop greenhouse that grows food year-round using hydroponics (no soil!) and bug-powered pest control. Inspired, Aiva learns to preserve basil with salt and builds a backyard cold frame using recycled stuff. They plant kale, carrots, and lettuce to keep the harvest going through the cold months. Two months later, her garden is booming—even the groundhog approves! Aiva whips up homemade pesto with her preserved basil, and it’s a total hit. From rooftop farms to backyard magic, this episode is packed with green goals, tasty food, and big eco-wins!
