seed starting and temperature range
I recently purchased an inexpensive plastic covered metal frame small greenhouse. I am trying to start seeds in it. Temperature regulation is difficult. What are the extremes of the temperature range to start the seeds with out freezing or cooking them?

Get a soil thermometer and you will find that onions, s pinach and parsnip seeds will grow in soil above freezing; radishes, carrots and cabbage in soil above 40 F.; corn, asparagus and tomatoes in soil above 50; squash, cucumber, beans and melons in soil above 60. For starting seed,you'll have better luck in early spring if you get a heating pad made for seed starting and put that under your flats of seeds. You greenhouse must have the ability to ventilate if it gets too hot.
