I need all the advice I can get. I am in Mesa so it's just as hot as can be. I
was planing on useing a cover. I'm not sure what the stuff is called but it's
just a heavy fabric shading. You can buy it from a roll at garden shops and
hardware stores. Even most pond plants couldn't take the full sun here. Do you
think this would help? I would also like to grow some in a hydroponic like
situation in the greenhouse. Do you think they would do well like this?

worried about regarding high humidity. 
Evaporative coolers loose efficiancy as the humidity goes up so I was
worried that in an already humid green house they wouldn't cool the air
enough to make a difference. 
Barry,
>So you live in Arizona and are asking about setting up an outdoor bog? 
>My first
question is do you live in the >desert, rim country, or mountains?  A
great deal depends on that, as John Walker noted. 
I live in the sweltering desert heat (but it's a dry heat <g> and only
118 yesterday).  I'm planning on setting up a shaded pond with a bog.  I
was planning on useing a standard pond liner. 
Thank you both for any information you can give me.
