Theoretically, we could be starting our outdoor planting today but even if the weather were sufficiently hospitable to accommodate outdoor activity—and it isn’t—it wouldn’t be anywhere near warm enough to initiate germination.  So instead, we turned our attention indoors and put together our seed-starting apparatus.

The first step was choosing a location for it.  We had originally thought to put it near the oil burner to take advantage of excess heat (I like to think of it as a variant form of cogeneration).  Based on the arrangement of our basement, however, there is no excess space there.  Also, there is no outlet nearby to plug in the lighting fixtures.

On the other hand, the spot in our storage room (or, as we lovingly call it, the Mouse Room) where we had temporarily stacked the components is directly in front of a south-facing window.  There is plenty of sun there and even on a cold day like today, it feels relatively warm.  As luck would have it, the extra height of the shelving unit we purchased (see February 18, 2013) elevates the three seed-growing levels to window height.  And what’s more, there is an electrical outlet under the window.  Without having to look too hard—really, without having to look at all—we found our spot.

We next assembled the shelving unit, the design of which is simple and ingenious.  The number of different parts has been minimized by making all of the shelves and post sections identical.  Therefore, there is less risk of a missing part and it is much easier to supply it if necessary.  The only other parts are the post bases and caps (and, strictly speaking, the latter are not required) which connect to the unit in the same way the posts and shelves connect to each other (and without fasteners).  The unit went together quickly and easily.

We then drilled holes in the sides of each shelf to connect the S-hooks from which the light fixtures will hang.  The shelves, constructed of heavy-duty plastic, have a double-wall design so rather than punch all the way through, we drilled only the outer face.  This meant making the S-hook connection blind (as a steel erector would say).  To get them into the holes, we had to slightly open one end of each hook.  Even so, they fit snugly and securely.

In the online and package illustrations, the chains for the light fixtures appear to connect about six inches inboard of their ends.  This would have been perfect so I was not surprised to find that in reality, the connection holes for the chains are only an inch or so from the ends.  To make our design work, we had to drill new holes.  To do this (and probably void the warrantee in they process), we had to remove the covers from the light fixtures, mark the locations, start each hole with awl and then drill them, being careful not to cut through the wiring.

For each S-hook, we drilled two holes, one for each end of the bottom loop.  As for the shelves, we had to unbend the S-hooks to feed them into the holes but because these connections were not blind (we had access to both sides) we were able to rebend them to make them tight and secure.

We hung the first light fixture using the lengths of chain provided and installed the two fluorescent bulbs.  We then tested the light’s operation and adjustability to make sure our measurements and techniques were practical.  Everything worked well and we quickly repeated the process for the remaining two light fixtures.

Now we needed power.  I have a big bin full of extension cords and it often seems that I have every conceivable variation except the one I need.  But I got lucky this time and found a relatively short one with receptacles for three grounded (i.e., three-prong) plugs.  We plugged the fixtures into the extension cord and then, using zip ties (how did I ever survive without them?), fastened the cords to the shelves and posts.  Finally, we plugged the extension cord into the conveniently-located outlet and switched the fixtures on.

The rig is now ready for seeds.  The sun will provide light and warmth during the day, hopefully enough to initiate germination of the seeds.  Once the seedlings emerge, the light fixtures will supplement the sun’s light and extend the length of the growing day (I did forget to get a timer with a grounded outlet so another trip to the Home Depot will be needed).
