Growing tropical plants in a cold weather greenhouse is possible with proper temperature control, humidity management, and insulation. These plants require consistently warm conditions, typically above 60°F, which may necessitate supplemental heating during colder months. Using thermal mass, such as water barrels or stone flooring, helps retain heat, while double-layered glazing and insulated walls reduce temperature fluctuations.
A heating system with thermostatic controls ensures a stable environment, preventing cold stress that could harm sensitive plants. High humidity is essential for tropical species, so regular misting or a humidifier may be needed. Adequate lighting, either through natural sunlight or grow lights, supports healthy growth, especially during shorter winter days.
