I live in XXtreme SW Utah at 3900' elev., north of St. George. Not sure
what zone, as it varies with the book. 6 I think. Gets down to about 20 in
the winter, 105 in summer. Snowed last week, so spring is about April 15th.

Anyway, my neighbor built himself a greenhouse. He now has tomatos already,
and we haven't planted any. He's got other stuff, too.

Now, my wife wants one. So do I.

Give me some do's and don'ts on greenhouses. We get horrible winds here
sometimes. What wood would be good, redwood? And is there any visqueen
material that has fibers in it that will make it stronger?

I have a Singer walking foot sewing machine, so can make up the panels, plus
any shadecloth arrangements I want.

All tips appreciated, including type of wood to use for main posts, types of
clear/shade materials, watering systems for inside, heating on marginal
nights, etc. Should I make the wall panels somewhat of a fold out for
ventilation? Good sites for plans?

TIA

Steve
