7 Tips to Keep Your Greenhouse Warm this Winter

As winter approaches, greenhouse owners face the challenge of keeping plants warm and protected. Proper heating can keep your plants thriving through the colder months without breaking the bank. At Blustal, we understand the importance of maintaining a consistent and efficient environment in your greenhouse. Here are seven top tips to keep your greenhouse nursery cozy and cost-effective this winter.


1. Insulate with Bubble Wrap

One of the simplest ways to retain heat is to insulate your greenhouse with bubble wrap. This affordable material creates an effective barrier against the cold by trapping pockets of air. Choose horticultural-grade bubble wrap, which is UV-resistant and more durable, and cut it to fit snugly along the interior walls and roof. Secure the bubble wrap with greenhouse clips or tape to avoid any gaps.


2. Use Thermal Screens

Thermal screens or insulating curtains can help you retain heat at night when temperatures drop. Install these screens across the roof and sidewalls of your greenhouse to help trap warm air inside. Automated screens can retract during the day to allow in sunlight and close at night to insulate the space. Blustal offers a variety of thermal screens designed to maximize heat retention and reduce energy costs.


3. Add Heating Mats for Soil Warmth

Heat is essential at the root level, especially in colder months. Heating mats placed under trays or pots provide gentle warmth directly to the soil, promoting healthy root growth. Not only do these mats warm the plants' roots, but they also reduce the need to heat the entire greenhouse, making them a cost-effective solution. Check out Blustal’s range of energy-efficient heating mats to keep your plants comfortable this winter.


4. Choose the Right Greenhouse Heater

Selecting the appropriate heater is crucial to maintaining an even temperature. Small greenhouses can benefit from electric fan heaters, which evenly distribute warm air. Propane heaters are another effective choice, especially for larger spaces. Blustal offers a variety of heaters specifically designed for greenhouse use, ensuring both energy efficiency and consistent performance. Consider pairing your heater with a thermostat to automatically control and monitor the temperature.


5. Seal Gaps and Fix Leaks

Even the best heater will struggle to keep your greenhouse warm if there are gaps or leaks. Check your greenhouse for any cracks, broken glass, or gaps around doors and windows, as these can let cold air in and warm air out. Use a weatherproof sealant to fix any cracks and make sure doors and windows close tightly. Blustal's weather-sealing products can help you easily tackle this task, ensuring your greenhouse stays insulated.


6. Use Compost or Hotbeds for Natural Heat

Composting organic material in your greenhouse produces heat as it decomposes, which can be used to warm your greenhouse naturally. Set up a compost bin or pile in one corner and allow the heat generated to raise the overall temperature. Alternatively, creating hotbeds by placing compost directly under your growing beds can provide direct warmth to the plants above. This eco-friendly option also enriches your soil for future planting.


7. Leverage Solar Gain During the Day

Maximizing sunlight exposure during winter is essential to keeping your greenhouse warm without additional costs. Ensure that any insulation, like bubble wrap or thermal screens, does not completely block the sun. Position plants strategically to receive as much sunlight as possible, and ensure that the outer panels of your greenhouse are clean, as grime can obstruct sunlight. Blustal’s specialized cleaning solutions are perfect for maintaining crystal-clear panels.
