How to heat a small greenhouse in winter?
Insulated Water Barrels Place several dark-colored barrels filled with water throughout your greenhouse. The water will absorb and store heat during the day, releasing it slowly during cooler periods, helping to maintain a stable temperature. Insulate the barrels with foam or blankets to minimize heat loss. Using Water Water is slow to heat up and slow to cool down, and therefore, can help both raise and maintain heat inside of a greenhouse. Large barrels of water that are painted a dark color, such as dark brown or black will heat up more quickly by absorbing more ultra-violet radiation from the sun.
How much warmer is a portable greenhouse?
A greenhouse is typically 8°F (4. C) warmer than the surrounding outdoor temperature. In optimal conditions with good insulation and sun exposure, this difference can extend to 20–30°F (11–17°C).

In optimal conditions with good insulation and sun exposure, this difference can extend to 20–30°F (11–17°C). This natural heating effect depends heavily on the structure’s design and local climate.
Will a portable greenhouse keep plants from freezing?

This setup shields plants from low temperatures, enabling continuous gardening throughout the year and extending the growing season.
