Each vegetable crop grows best in its own range of temperatures. The optimal temperature range for peppers and eggplants, for example, is 70Â° to 85Â°F; pollination will not occur if the night temperature falls below 55Â°F, and blossoms may fall if the temperature rises above 85Â°F.ach vegetable crop grows best in its own range of temperatures.

Stem-walls are foundation systems constructed in three components; a spread footing to transfer load to the underlying soil, a (typically) masonry foundation wall, and a poured slab.
