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.

Slab Foundations. The two basic types of slab foundations are the monolith and the stem wall. Monolithic foundations are poured as a single form, with the outside edge, about the width of the wall, being 10 to 12 inches deep and the center of the slab typically 4 to 6 inches deep. A stem wall foundation is poured in multiple parts.
What youâre seeing here is a header built with a 2Ã6â³ bottom plate, 2Ã4â³ cripple studs, and a 2Ã4â³ top plate resting on the adjacent block walls. This header spans a 6â² opening and supports 4 floor joists (with 2 stories and a roof above it). The lowest point is at the middle and it sags down about 1/2â³.
