Greenhouse heating question

 

In another newsgroup, there's a discussion about heating a greenhouse.
Electric heaters were mentioned.  Also kerosene, but comments were made
about fumes and stickiness.  Someone recommended a plain propane barbecue.
It was stated that the CO2 would be good for the plants.  I was wondering
about the CO produced, and what the levels would be.

What is the best/worst ways to do supplemental heat in a greenhouse?

Strange. I always used sunlight to warm a greenhouse.

It depends on how cold the nights are.  I use an electric heater at
night to keep the temperature warm enough to prevent stunting the
plants. As soon as the sun comes up I have to watch the thermometer to
make sure that it doesn't get too hot.

The only time I run the heater is when I have seedlings in the
greenhouse.  I do not try to grow stuff during the winter since the
quality of produce is not worth the cost.

perhaps you should consider patenting that technique and attach a a switch
so you can turn it on at night.

 



Use a layer of rocks on the floor to hold heat from the daytime sun.
This isn't rocket science.
