Question: Once the seeds of my snapdragons, zinnias, and gazanias have germinated, how cool can I keep the greenhouse?

Answer: The ideal temperatures for growing seedlings are from 60 to 70F during the day, and from 55 to 60 at night. Temperatures can vary slightly, but don't let the greenhouse get too hot or too cold.
