Frequently Asked Questions

AI
For Canadian winters, a walk-in tunnel or polycarbonate greenhouse with proper insulation and ventilation is ideal. Look for models with heavy-duty PE covers or double-wall polycarbonate to retain heat and withstand snow loads.
If you are starting seeds indoors or growing in low-light areas, a greenhouse with integrated LED grow lights is highly beneficial. It extends the growing season and ensures seedlings receive sufficient full-spectrum light for healthy development.
Most outdoor greenhouses come with ground stakes and guy ropes. Ensure you anchor the structure firmly into the ground, especially in exposed areas. Some models include reinforced frames or additional window vents that can be secured to prevent damage.
