We need greenhouse starts, both for our own use, and for sale.


With a large greenhouse (24' x 148'), we can generate tens of thousands of dollars annually in starts, as well as supplying our own vegetable starts.

This will use solar power for temperature control, and will use our own biodiesel for winter/spring heating.


  • 2010-09-30 project begun.
  • 2011-03-12: greenhouse kit arrives from Steele Greenhouses.
  • 2011-10-20: arches raised.
  • 2012-03-25: skinned.
  • 2012-04-11: dividers complete
  • 2012-04-15: table toppers built
  • 2012-04-22: doors complete, with auto closers and stay-open hooks

Goal or deliverable

A 24' x 148' greenhouse, set up for producing transplant propagation starts.

Timeline, schedule, or end date

time-related aspects of the project, which may include intermediate deadlines, dependencies, etc


Design for greenhouse tables based upon several thousand square feet of stainless steel mesh obtained from BC Auctions and painted 2"x6" lumber from the horse fence across the frontage that we salvaged when we put up deer fencing.

generally, a numbered list of tasks, performed in order, that will together accomplish the project's goals or deliverables

  1. Obtain quote for greenhouse DONE
  2. Siting and permits DONE
  3. Construction and assembly
    1. Greenhouse:
      • layout location DONE
      • assemble and raise arches DONE
      • install purlins DONE
      • build gable ends and dividers DONE
      • skin main plastic DONE
      • skin gable ends and internal dividers DONE
      • build and install doors DONE
      • assemble roll-ups and cranks DONE
      • improved drainage DONE
      • raise floor with soil or other materials Deemed not necessary.
    2. Propagation benches:
      • Cut list for each two-layer bench:
        • top: 108"x42" pre-made panel made of rolled expanded stainless steel and 1.5" lumber.
        • pedestal columns: 2 each 2"x6", 29" long.
        • pedestal bases: 2 each 2"x6", 35.2" long, 45° at ends, alternate.
        • end braces: 4 each 2"x3", 48.8" long, 45° at ends.
          • chop 2"x6" first, then rip to yield two braces
        • centre brace: 2"x3", 64.0" long, 30° & 60° at ends, alternate.
        • centre brace: 2"x3", 62.2" long, 30° & 60° at ends, alternate.
          • Make four braces from a single 2"x6" of at least 135" long:
            1. chop end to 60°
            2. chop alternate 30° at 68.7" on long side
            3. chop final alternate 60° cut at 68.7 on long side
            4. rip both pieces to yield the 62.2" braces, the shorter of the two
            5. chop the longer of the two halves (at 30° or 60° end) at 64.0"
        • bottom tension strut: 102" x 1.5" x 1.5", ripped from 2"x6"
        • long dimension centre mesh support: 4 each ~46.5" 2"x3" Due to irregularities in short dimension supports, each must be measured and cut individually.
        • top supports: 4 each 17.5" 2"x6", ripped in half at 45°, joined to make an "L" shape.
        • 2"x3" lumber is actually 2"x6" lumber ripped in half.
  4. Finishing, wiring, irrigation, heating, etc.
    1. Heat
      1. locate and plumb biodiesel boiler for producing hot water for seedling heat.
      2. obtain PEX and valves so we can have each table on a separate heat zone.
    2. Bring semi-permanent electric power in, at least #10/3
    3. Irrigation
      1. tap into field irrigation system at the NE corner, where we luckily hit a main and thus have it located
      2. plumb 1" mainline along the long dimension
