When you walk into Caledonia Regional High School, you are greeted with long hallways lined with colourful posters and student artwork. This spring those hallways will lead to a new kind of classroom — a four-season greenhouse.
Located in the small community of Hillsborough, about 25 kilometres south of Moncton, the school hopes its geothermal greenhouse will provide students with a hands-on learning opportunity.
A geothermal greenhouse uses heat from the ground to make the temperatures inside the greenhouse suitable for growing.
Principal Emily Ostler Colpitts said the plan is to open the greenhouse in April, and students will grow a variety of vegetables almost all year round.
