Of course, Obamaâs record on job growth is also much worse than President Reaganâs record. Net job growth has declined under Obama. By the end of the second year of their terms as president, economic growth under Reagan averaged 7.1% , under Obama an anemic 2.8%. (IJ Review)
If the proper temperature is not maintained within the greenhouse, the tomatoes will fail to produce. You should plan on keeping the greenhouse above 60Â°F, but below 90Â°F. In most areas, this will require some heating during cold weather.
1 Before planting, put black or red plastic over the soil to pre-heat the soil, warm it up faster. 2  Plant tomatoes when the soil temperature is above 55Â°F (how do I find that out?) and the air temperature does not go below 45 degrees at night.ut the magic is not associated with them being in the ground versus being in a planter, it's in the soil temperature. Tomato roots will not grow or provide nutrients to the plant at soil temperatures of 50Â°F or below. Researchers have found that the ideal root temperature for tomatoes is 70Â°F.
