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. Advantages of stem-wall foundation systems include: 1  less fill required for sloped lots (the foundation wall can built at different heights to accommodate a sloped lot) 2  a greater free-board distance from the top of slab to the surrounding grade of the lot can be accomplished giving the home a more pronounced appearance.
A crawlspace foundation is where the home is supported off of the ground level by approximately 2 feet. Stem walls extend from the footings around the perimeter of the foundation to support the home. Often times an alternative is used instead of the stem wall. This is called pier and beam.
