Waiting for that first hosta spear to break through, or the first signs of daffodils, crocus, and hyacinth to appear can be agonizing. Ease the agony by starting seeds indoors.
When March arrives a lot of zone 5 gardeners get an early start on the growing season by sowing a few of their favorite annual flowers and vegetables seeds indoors. And it doesn't take a lot of fancy equipment to accomplish this goal. Use these easy to follow directions to make your own grow-light shelving. This project only takes a couple of hours to complete and you'll be making two grow-light units which will allow you to start four flats of seedlings.
Material
One 1x12 board (a 12 foot length will make two shelves). Cost - $21.00.
2 1/16 inch screw hooks (five to a pack). Cost - 94¢.
Concrete blocks (or other suitable supports). Cost - $1.06 each (four will provide support for two grow lights).
Total cost - about $44.00, plus tax.
Tools
Tape measure
Crosscut handsaw
Drill and bits
Gripping pliers
Safety goggles and leather gloves
My shelves are 5 feet 4¼ inches long. You can use this measurement, or choose the best length that works for the space you have. Purchase shorter shop lights if you are limited for space. Cut your shelving to length with the handsaw.
Measure in 10 inches from each end of the shelf and mark the center. You can pre-start a hole using the drill and a small bit, making sure your bit is smaller than the diameter of the screw hooks: if you're using a 1/16 inch screw hook, use a 1/64 inch bit to drill a starter hole. If you're using soft wood, you can probably screw the hook into the wood without drilling a starter hole. Use constant pressure as you screw to keep the hook straight and use the pliers if needed.
Place your shelves on top of the concrete blocks and hang your shop lights from the hooks, using the chain. Some seed-starting gurus recommend using one warm white fluorescent tube and one cool white tube. This provides a good blend of light color.
Hang the grow-lights two inches above the surface of the seed-starting mix after you have sowed your seeds. After germination, and as your seedlings grow, raise the lights periodically to keep the fluorescent tubes a constant two inches above the seedlings' topmost leaves. For convienence, an electric timer may be purchased. Keep the lights on twenty-four hours a day until the seedlings emerge; afterwards, set the timer to allow 16 hours of lighting per day.
About TC Conner
I have too much lawn and I'm trying to turn it all into gardens. But I still like grasses.

I do something similar, using a folding table, I only get one set of lights, I like this increase in use of floor space! I get carried away with things I want to start before I am ready to heat the greenhouse (zone 3).
I do two other things that may or may not be helpful to some, I put clear plastic over the light and allow it to hang down to the edges of the table....I use clothespins to hold the ends together. Serves 2 funtions: keeps in moisture and keeps my cats OUT!! The other thing is to use old heating pads under the seed flats for germination.

Thanks for sharing this. Simple can be better. No need for expensive shelves and grow lights.
