Although it is cold, and winter is still here. We are busy seeding and trying to expand how we germinate and seed out flats so we can produce more seedlings for sale along and get more into the ground on our farm as well.
We noticed that at night out seeded flats soil temperature goes down to 8C although the greenhouse air maybe at 16-22. So we made heated germination tables, and they have produced results within days.
