Interesting, Bobberman! You must have gotten it all past the "glitch stage."
I am trying some things in my greenhouse this winter. I really set it up nearly 20 years ago to grow plants in flats. The 200sqft greenhouse has a natural gas garage heater.
The cost of running that garage heater thru the winter discouraged me and I have never turned it on before March. It works fine from there on until I get all the plant starts out of it for the growing season outdoors. A few
summers, I have had some extra plants and decided that putting them in the ground in there was safest. Basil and some tomato plants did okay - they could take the heat but keeping them watered was a bother.
This fall -- I decided to move some late-sown bok choy out of the garden into the soil in the greenhouse. I pulled my main bench
out and they have room. Along with the transplants, I sowed some seed for bok choy and some other Asian greens. These things are about as good in the cold as radishes.
Well, before the outdoor temperatures dropped into the teens, I had a nice harvest of the bok choy transplants! Didn't take them all but, nearly. I was just noticing today that the ones left have been growing! I should be able to get all of them before it gets real cold. We are on kind of a slow slide this fall. It has been below zero by this time but - not this year.
The seed sprouted in October and the seedlings are growing but very slowly. When the forecast for outdoor temps to be about 15°f or colder, I cover all the plants with another layer of plastic film. I've got pvc hoops set up in there for that. This is kind of the way I've been keeping my potted rosemary alive the last few winters. I just decided to provide a little more room and plant some Asian greens in there!
You have written on the forum about your winter greenhouse before. This winter - I'm joining you!
