Little plants in February?

17 Feb

Despite the lack of blog posts, we have been doing stuff on our little greenhouse project. Not much, admittedly, but stuff nonetheless. For instance, during the long, slow season of winter, we discussed a long-term plan for the project and helped some middle schoolers get projects started inside for the spring.

And then there was yesterday. 39 degrees outside; 104 degrees inside. Yep, that’s right. A 65 degree temperature difference. We all rushed out to the greenhouse to bask in the heat, and then promptly opened all the doors up and ushered a cold breeze inside. Oh yeah, we also planted up 72 row feet in greens for our spring CSA program. It’s exciting to think that spring is finally here, in the greenhouse at least.


The greenhouse in below-zero weather

8 Dec

It is a chilly one here in Northfield, MN. After a fairly warm November and December, we’re settling into the seasonal norm of well below 20 degrees F. We were incredibly interested to see how well the greenhouse did on a sunny morning with an outside air temperature of -2 F.

Guesses? Guesses?

The greenhouse is a whopping 28 degrees, which is 30 degrees warmer than the outside air temperature. We don’t know whether or not to attribute this fact to the amount of sun we’ve got or the insulative layer of snow on the sides. Either way, we’re incredibly pleased!
