How to Use a Greenhouse in the Winter

Using a modern greenhouse in winter is all about harnessing the power of the environment to benefit your plants. If you’ve ever wondered how to build a winter greenhouse, here’s how we recommend doing it based on our extensive experience and research:

Understand your greenhouse’s design

Different greenhouse styles serve different purposes. For instance, the classic peaked-roof style is popular for its timeless look and practicality, especially in shedding rain and snow.

On the other hand, gothic arch or onion-shaped greenhouses, with their pointy roof lines, are designed to handle snow and wind better. Knowing the design advantages of your greenhouse can help you optimize its use in winter.

Positioning is key

Location matters. Ensure your greenhouse is positioned to get maximum sunlight during the shorter winter days. This not only provides natural warmth but also ensures your plants get adequate light for photosynthesis.

Monitor and control temperature

Winter can be unpredictable. Regularly check the greenhouse temperature in winter inside your greenhouse. If it drops too low, consider adding heating solutions.

One effective method we’ve seen is using free greenhouse heat techniques, such as utilizing compost piles or water barrels.

Conversely, on sunny days, it might get too warm, so ensure proper ventilation.

How to Keep a Greenhouse and Plants Warm in the Winter

Keeping your greenhouse and plants warm during the winter is crucial for ensuring a thriving garden. Here’s how we at Greenhouse Emporium recommend you achieve this, based on our years of expertise and research:

Automated heaters

These are a gardener’s best friend during the chilly months. Automated heaters maintain a consistent temperature, ensuring your plants remain cozy. We offer a range of heaters tailored to different greenhouse sizes and needs.

In our experience, investing in a good heater pays off in the long run with healthier plants and fewer winter casualties.

Insulation with bubble wrap

Bubble wrap is an excellent insulator. By lining your greenhouse with it, you can significantly improve heat retention. Our research indicates that this method can increase the internal temperature by several degrees, making a noticeable difference on frosty nights.

Water barrels

These act as natural heaters. Black barrels filled with water absorb heat during the day and release it at night. We’ve seen many of our customers benefit from this age-old technique, especially those in extreme climates.

Fleece tunnels

These mini-greenhouses within your greenhouse offer an extra layer of protection. They’re especially useful for delicate plants that need a bit of extra warmth. We recommend using fleece tunnels for seedlings and tropical plants that are more sensitive to cold.

Choose the right greenhouse

The design and material of your greenhouse play a significant role in its insulation properties. For instance, our insulated greenhouse kit is designed to offer superior insulation, making it perfect for colder regions.

If you’re craving fresh salads during the colder months, winter lettuce is your answer. It’s hardy, can withstand cooler temperatures, and provides a fresh, crisp addition to your meals. Our research indicates that varieties like ‘Winter Gem’ and ‘Arctic King’ are particularly resilient.
