Year Round Greenhouse, How Practical?

 In a moderate climate (Oregon, about 100 miles from the coast), how
practical would it be to try to raise vegetables year-round in a
greenhouse?

I know someone who raises herbs commercially year round in greenhouses.
 I think she has four of them.  She sells the fresh herbs at a farmers'
market.

Besides providing protection against winter frosts and freezing, a
greenhouse protects plants against being beaten down by wind, rain, and
hail (except for severe hail, which can break the greenhouse panes).

With screens for the transoms (windows that open), a greenhouse can also
protect against many insects, especially grasshoppers.  However, that
can also prevent the use of bees for pollination.

In OREGON???

Heh. I went to Oregon State, in Corvallis. Three of the 4 years I was
there, it on September 1st the temperature dropped to 50 degrees and
it started to rain. The temp never changed and the rain never stopped
until May 1st.

OK, an exaggeration, but not much of one. Now, Corvallis is about 50
miles from the coast, so it sounds like Jeff is somewhere in Cascade
Range. You can count on more snow up there than in the Willamette
Valley.

Jeff, it really depends exactly where you are. I knew people near
Salem who raised fuchsias year-round, and they probably are less hardy
than some vegetables. Also, it depends what you want to grow. I'd give
up on melons and cucumbers, but lettuce, broccoli, cauliflower, peas
might all do well.

Some of my worst sunburns came on overcast days. Melons and corn may not
grow in a green house during his winter, but with nothing physical
blocking his sunlight, he should be able to grow lettuce, kale, chard,
broccoli, cauliflower, and maybe even peas.
