How warm or cold?
We are facing colder winter than average but how cold is it for vegetables?
I bought a temperature indicator and set it inside one of my vinyl tunnels where spinaches are planted. I saw the indicator showing the temperature inside the tunnel 10C while 7C outside. That shows the tunnels are effective to warm the air inside but at the same time shows this winter is severely cold. Even if the temperature inside is warmer, the vegetables seed inside the tunnels will not germinate for a while till the temperature would be at least 13C.
I think seeding in the mid winter might be challenging but might be a good opportunity to create and test new method such as the vinyl tunnels.
