I am planning to start some seed indoors for next spring season. Since the weather is still a bit cold, I am going to be using a heated bed (actually it's a styrofoam box with some sensors and a heat element to control the temperature quite precisely).
The seeds will germinate on paper towels, and then I will move them to small pots and into an outdoors greenhouse until the minimum daily temperature is about 10-12c/50-55f, then they will be planted on the soil.
The greenhouse is covered with polyethylene plastic, the temperature inside is not controlled or monitored. I haven't checked but I think it stays above 10c degrees.
Wont the seedlings have issues with emerging on a ideal temperature and moving them to an environment that while not cold, it has no temperature control?
My concern is that the seedlings may get shocked and die when moving them to an environment that is colder of where they sprouted. Is not that the growing environment will be so cold that is hazardous for the plant, but the germination box temperature will be almost perfect. So, I don't know if the difference between the two environments will cause issues.
