A table top grow light set from Gardeners Supply is over $100. At Home
Depot, a pretty similar 48 inch shop light, bulbs, and chain can be had for
about $35.

My question is about how to construct a support to hang the shop light
under. Because of a general lack of space it's going on the kitchen table
so at my dear wife's suggestion I'm not thinking of a PVC pipe assembly etc.
Ideas?
