Natural Gas
When they are burned, natural gas, propane and liquid fuels
give off carbon dioxide, and there are specialized carbon dioxide-generating burners designed for this purpose. These are
most commonly used in large greenhouses and are less suitable
for small indoor gardens. These burners are a heat source
as well, which must be taken into account when planning
your garden’s cooling requirements. Since there are
inherent dangers in their use, such as flames and fuel
in an enclosed space, I do not recommend their
use in home gardens.

They are a popular in home indoor gardens, but tanks

may be cumbersome compared to other options.
