Last night, with the weather forecast predicting lows in the 40s, a
friend suggested I cover my tomato and pepper plants. I put dry cleaner
plastic over the tomatos and glass jars over the peppers. This morning,
with the weather forecast predicting showers and highs in the mid 50s,
I decided I could just leave the plants covered. I figured the plastic
would divert any rainwater to the base of the tomato and I could water
the peppers tomorrow.

Now at work, however, I began to wonder if leaving the peppers under
the glass jars would deprive them of oxygen? The plants are small, not
more than 4 or 5 inches tall and the jars are inverted resting directly
on the soil.

Should I have removed the jars, or at least raised them slightly off
the ground? And are the tomatos ok?

You worry too much about oxygen. In sunlight, plants produce oxygen--not
consume it. If you are worried about such things, oxygen which is not used
in quantity is in about 20% concentration, while carbon dioxide which is
used in quantity by green plants is in less than 0.1% concentration.
