There are numerous.
Diy solar water greenhouse heating systems.
To control the temperature in our geodesic dome greenhouse we used a water tank for passive temperature regulation and also an old car radiator for active heat exchange.
These types of small steps and areas of understanding can make your diy greenhouse even more enjoyable while saving you money and improving.
A better option is to invest in a heating system.
Heat sinks are one of the best tools to serve this purpose.
Heat sinks use water to trap warmth and release it slowly.
To use a gas or electric heater can be costly.
The primary challenge with greenhouse growing is stabilizing these temperature swings.
Now these are temporary palliative solutions for heating a greenhouse.
Closed loop solar heating system.
Finally for your passive solar heating system to work you must have a way to store the heat absorbed during the day and release it at night.
Here s how a solar powered water heater works.
Next you must insulate your greenhouse to prevent heat loss.
The heated water then flows into the storage tank before it s channeled into the heat exchanger.
After using a car radiator for heating and cooling a greenhouse for many years now we thought it is time for an update.
Ideally you should use electric fan heaters which can be easily moved around the greenhouse thus preventing the apparition of cold spots and reducing the risks of plant disease.
