Blueberries are a very exciting crop to grow in automatic retractable roof houses. While it is common for growers to begin with conventional tunnels, retractable roof houses are the next logical step when growers want to harvest during the warm and hot times of the year when conventional tunnels are no longer optimal. Growers will also enjoy producing firm berries with great flavor and a long shelf life at the same time as reducing chemical residues.

Spotted wing drosophila can also be managed easier in a retractable roof since the excellent ventilation through the roof allows the walls to remain closed helping to prevent pest entry.

By implementing the retractable roof production system you have the ability to improve your return on investment by:

  • Expanding Production Possibilities: Shift or extend your harvest season, produce more berries per plant, grow higher quality berries and expand your possible production locations to meet market demands
  • Reducing Input Requirements: Reduce costs for labor, fungicides and insecticides
  • Reducing Risk: Protect crops from variable weather patterns and catastrophic storms
