I add lime chips to my paph potting mix and seem to get better results,
however I would advise checking your water's ph level first.
Dr Braem and the Bakers advise in their books that lime should not be
added to the mix of some species as it dissolves in cold water and may
develop toxic

I read the Science article. Factually, however, increased CO2 does lead to
increased plant growth, as evidenced by its commercial use in glasshouses
around the world and by forest trials in which local CO2 levels are enriched

Mark Sullivan's post initially mentions the effects of carbon dioxide on
orchid growth but then gets on to an entirely different subject, carbon
dioxide and global warming. The negative information about the ability of enhanced
plant growth to control global warming through carbon fixation
As I understand it, only 38 industrialized nations have mandatory limits under the
Kyoto protocol. The rest, e.g., China, India, Indonesia, Brazil, Mexico, etc... are
supposed to make voluntary cuts.

I believe Heinrich Beyrle may be moving in the direction you are interested in.
He works with Australian species, and I know he has had expereience with
the mycorrhiza fugi and Australian orchids. His website can be found here:

What specific fungi are you interested in.
Hello Mark,
Global warming isn't the problem, the problem is that the people who are in charge
have a different agenda and priority. Alltough scientists find it rather difficult to
come up with a solid pointer to the fact it is happening (the majority of the research
has a statistical

Hi all.
I would be very appreciative if I can get help in relation to orchids that
have been germinated asymbiotically and then introducing the mycorrhizal fungi
to the orchid when deflasking the seedlings.
Is anybody aware of
You might try contacting Dr. Lawrence Zettler of The Illinois College in

Dear Dick;
Our friend member Aaron Hicks, of the OSP, knows of several sources
about mycorrhiza and orchids, cited in his excellent orchid seed propagation
book. People are starting to cultivate mycorrhiza
Fredrick JM Depuydt faults the data indicative of Global Warming as
statistical in nature. Please note that an important concept of the Philosophy of
Science is that ALL data is statistical. Information that cannot be expressed as
within an explicit statistical probability is without meaning.
as per some plant doctors at Texas AM:
1. Yes, higher ranges of CO2 appear to be beneficial. Initially.
2. The effects are transient, so forget it. The plants will return to normal rates of
growth, because like all living things, they compensate to their environment. This is
very much akin to a
Dick,
Nutrient balance can indeed be a problem, when one tries to germinate orchid
species
seeds symbiotically on media that contain sugars etc.
Asymbiotically germinated orchid species seedlings can usually be infected
very easily with their symbiont and without getting into nutrient balance
Actually what interested me about the Carbon Dioxide Theory Debunked
article was that elevated level of carbon dioxide caused rapid growth
the first year, but was limited by a nutrient deficiency the following
years. On this forum when carbon dioxide on orchids has been discussed
