[Arid_gardener] greenhouse question

[Frank & Kirsten Walker]

Hi,
I am thinking of indulging in the smaller harbor freight green house
that is currently on sale, but I have a few questions.

What type of placement do you recommend for the structure?

Am I going to need a cooling/heating system for year round gardening?

Does anyone on the list, living in the Tucson area, have one of these
that they would be willing to show off?

Any advice would be helpful, as this is would be my first attempt at a
greenhouse.

Thanks in advance
Kirsten
