Re: [OGD] Unvented Gas Fireplaces vs Orchids

[Thomas Hillson]

Natural gas contains ethylene, which causes bud blast in many plants, 
and ripening of fruit, and many other influences on plant growth and 
development. It is not classified as a plant growth regulator but 
probably should be. Any un-vented gas appliance is going to have the 
problem of releasing un-burnt gas containing ethylene in to the air. 
As the concentration builds up, it will cause lots of bud blast on 
your plants. Always use vented gas appliances in a closed environment 
like a greenhouse. If you want more information look up ethylene on 
the internet.

Colleagues:
As editor of a monthly orchid society newsletter I receive questions 
and requests for information from our readers.  I pass this one on 
through the OGD because I suspect it may affect others too - as 
follows:

Is there a known correlation (read cause and effect relationship) 
between the use of an unvented gas fireplace and the blasting of 
buds, along with early demise of flowers, when orchids are grown in 
the home?

Thank you for any direct information or useful leads you can provide 
to help solve this problem.
