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.
I start tomato and pepper seedlings in an unheated greenhouse with heat mats. I'm not sure exactly what temperature it is right around the plants, but with the warm soil and a plastic dome cover over them, they do very well. The ambient air in the greenhouse gets into the 40s at night, but never below freezing.
