Re: (OT) heat and CO2 in a greenhouse

[Allen Johnson <allen_h_johnson at yahoo_com>]

One of the problems with trying to grow plants ie.
vegetables in a greenhouse is that very little CO2 is
left after 9AM as the photosynthesizing plants absorb
so much CO2.  The CO2 concentration is not to keep the
greenhouse any warmer.  To grow vegetables and other
high productivity plants in a greenhouse some source
of CO@ is necessary.  However, for a home greenhouse
composting leaves liberate sufficient CO2 in a home
greenhouse to keep the plants growing well.  Of course
brewing your own beer or wine will also generate a
sufficent CO2 for plant growth, and you get a decent
beverage out of the experience.  The only worry I
would have with the propane burner is CO carb9on
monoxide, which we all know is poisonous.
