Hi, and welcome! Thank you for joining. In this video, I share some tips on how to keep your greenhouse warm during the winter when the sun goes down. It is essential to have a thermometer to track the temperature and humidity. I will also be providing a video on heating the portable greenhouse in the coming week.
I outline the tips on how we keep our greenhouse warm during the winter below.
To keep the greenhouse warm, I use heat sinks. These thermal masses are 55 gallon and 33-gallon water containers. The black drums are ideal. They absorb heat during the day when there is sunlight, and they slowly release the heat during the night. Water has a high specific heat capacity.
Keep the soil in the pots moist. The moist soil adds to the thermal mass.
Insulate the windows, especially on the Northern side. Use thermal curtains or bubble wrap.
I add a propane heater. The heater is vital for me as a number of the plants in the greenhouse are tropical. I use the 20-pound cylinder bottles as they are cost-effective. I get the bottles filled at Ferrel gas for a lower price. It’s $11 per bottle. Ferrel gas provides a free refill for every four refills.
I included a fan in the greenhouse for air circulation. The fan also strengthens the structural integrity of the plants.
I hope this was helpful. Do you have additional strategies used to keep your greenhouse warm ?
