Winter Greenhouse 2015

Tuesday the 17th of November, I am summoned to Minneapolis City Hall to answer for my "illegal addition" greenhouse, because I did not apply for a permit.

In the spirit of that upcoming hearing I built this, this past weekend, out of repourposed lumber.





Three inches of compost from the garden, and a 2.5" top layer of an "organic", "For raised beds" soil (from two corporations that shall not be named.) The back wall is covered with a tarp, the window cut out and taped. I have partially enclosed the surround with 4mil poly, not yet fully enclosed as the weather this weekend was more like spring, 60 degrees outside and perhaps eighty in the greenhouse. I'm enclosing the beds in a greenhouse within a greenhouse, to maximize heat collection. The window can remain open to help moderate the heat in the greenhouse, and heat the house on sunny days above 20 degrees. 

I planted various lettuce, spicy baby greens (mesclun), Arugula, spinach, basil, cilantro, and some red onion plugs left over from the spring. On the top rack I intend to set some cherry tomatoes and maybe beans and peas in black pots (to absorb heat.) If all goes well I should harvest something around the New Year.

I staggered the beds so they can be racks of garden starts, beginning around March 01. The sun will climb higher and higher after Dec 21, about an angle of 21.5 degrees to the horizon, to about 68.5 degrees June 21. If I built the racks upright, the back of the bottom two racks would be shaded by mid-march. 

More on the detail of the construction, after the hearing.

  1. Great work. Please keep us posted after the hearing. If it goes wrong I would love to start a petition online and give that city a taste of public shaming.

Comments, questions and adoration is welcome. Excessive adoration will be appreciated but expunged. Vitriol, lies and general ugliness will be enjoyed but not published, except when such ignorance is exceptionally entertaining and lends well to an argument I am trying to make, in which case I may choose to publish it with a reply. Otherwise, feel free to say whatever you like.
