Keeping greenhouse warm: A simple DIY method for gardeners

Maintaining a stable temperature in the greenhouse is crucial for healthy plant growth. Many people buy specialized equipment, such as heat pumps, central heating systems, hot air heaters, electric, and gas heaters. However, a simple and inexpensive way to protect your plants from the first chill exists.

One day we go out for a walk in a light jacket, enjoying the sun's rays, only to pull out a thick scarf the next morning and wrap it around us. Not only are people exposed to temperature fluctuations; unexpected autumn frosts can pose a serious threat to greenhouse crops.

You don't have to spend a fortune on specialized heating devices to protect your plants from unexpected frosts. All you need are a few basic items easily found at home or in a store. The best choice will be candle inserts, which burn much longer than regular candles. This is the perfect time to stock up - before All Saints' Day, candle inserts are available practically everywhere.

Prepare:

• Two clay pots of different sizes, with a hole at the bottom,
• a candle or candle insert,
• a clay saucer,
• 3-4 small stones.

How to make a pot heater?

1. Prepare the base: Place the stones at equal intervals on the saucer, creating stable support for the pots.
2. Arrange the pots: Place the larger pot on the stones. Light a candle inside it, then place the smaller pot on top, creating a "cap."
3. Leave some space: Ensure there's a small gap between the pots for adequate air circulation. Otherwise, the candle may go out.

The candle heats the clay pots, which, in turn, releases heat into the environment. This raises the temperature in the greenhouse, protecting the plants from cold temperatures.

Clay pots get very hot. Always wear protective gloves when moving the heater. Check carefully to ensure the structure is stable, and periodically confirm that the candle is still burning.

This method is simple and inexpensive. It can be used in autumn and spring and helps protect plants from frost.
