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.
What is a floating slab? A floating slab is a concrete slab foundation on which a structure is built. A floating slab does not have frost protected footing and is designed to âfloatâ with the ground during the winter months. Floating slabs are most commonly used when building a detached garage or shed. A floating slab cannot be used if the structure that is built upon it is attached to your house. In this case you will need frost protected footings and a block foundation.
