As we enter the early days of February 2026, reaching this point has certainly posed its challenges. The weather has returned to what we expect for our hardiness zone, with temperatures plummeting well below freezing. You could say that February has arrived with a fierce roar. In today’s article, I will share tips on how to keep the dome cozy throughout the winter months. Additionally, you’ll find a video highlighting my personal experiences on this topic, along with a few photos from today’s adventure at the dome.
How to Maintain Warmth in the Dome During Winter Months VLOG
In the video linked to today’s article, I share my personal strategies for retaining heat in the dome. Join me on a sunny 16°F day, when the geodesic bio dome’s interior temperature soared above 60°F. You can almost feel the sun’s warmth radiating through the video as I provide tips on how I manage to keep costs low for backup heating while staying cozy inside the dome during the coldest days.
The video featured in my post comes from Bren Haas’ YouTube Channel. You can find most of my videos embedded on my personal website.
Keeping the Dome Warm During the Cold Winter Months
While it is certainly a challenge, enjoying tropical plants and wintering over your favorite specimens from the Ohio summer garden is not impossible. To create the ideal environment for warmth and heat retention, here are some essential factors to consider:
- Structure: The location of your growing structure and its construction are crucial. For winter growth, ensure the structure is positioned in full sun. Start with a solid foundation that can withstand snow and cold. Domes are renowned for their ability to resist wind due to their shape. If your design is structurally sound, it will endure any conditions. Additionally, the materials used for wrapping are vital. My dome is securely attached where the plastic meets the wood. There’s so much to share on this topic, but this post can only touch on the essentials.
- Inside Content: The primary consideration before winter sets in is gathering items that aid in passive heating. My structure is filled with soil, water, stones, rocks, and an abundance of plants. Water-holding containers, including my small koi pond, make a significant difference in heat retention.
Just a few of my favorite things about keeping the dome cozy. This is the ultimate winter gardening adventure.
