The past few weeks have been single digit nights, and below freezing days. That's a typical January here in northern Utah. Despite all this, I must have been doing something right with the mini greenhouse. The thermometer has been reading anywhere from 20°F (-6.7°C) to 40°F (4.4°C) in the mornings. On the coldest mornings, I'd just stick my hairdryer under the plastic and blow hot air for a few minutes. The temperature would rise to 50°F (10°C) or 60°F (15.5°C), the frost that had formed on the inside of the plastic would melt, and the temperature would hold for most of the day. It was overcast and cold but the sun still got a little warmth in there. A few tiny sprouts started popping up, and I was praying the little things wouldn't freeze.
Over the past few days, however, it's been sunny and in the high 40s, so the patio has warmed up to almost 70°F (21°C) and the mini greenhouse has been around 80°F (27°C) with the door open all day long. With it shut, it was skyrocketing to above 100°F (38°C).
With all this warmth, look what has been happening in the greenhouse! Sprouts of Cherry Belle Radishes, Black-seeded Simpson and Mesclun lettuces popping up all over! I also planted some peas in another pot with some sticks for them to climb up to the next shelf a few days ago. I'm still waiting for those to pop up.
Cross your fingers these bluebird winter days last, and my plants really get going. Gardening in this mini greenhouse in the winter is really scratching my gardening itch.
Good job.
