Starting seeds and growing seedlings indoors allows you to begin your spring plants in late winter. This gives them a chance to become strong and healthy before being moved outdoors to the garden. The greatest issue with indoor growing is providing the proper amount of light. Though a window may work, in winter and early spring there is often too little light for proper growing. Making an adjustable grow light stand to support fluorescent fixtures provides the needed light.
Cut four 55-inch lengths from the ¾-inch diameter PVC tubing. Hold the tubes to the cutting surface with clamps so they don't roll around while you are cutting through them with the hacksaw.
Cut four 26-inch lengths from the PVC tubes for the upright legs. Cut two 22-inch lengths for the bottom supports.
Slide two ¾-inch PVC T-joints onto each piece of the bottom support tubing. Twist the joints so the center opening is facing up.
Attach a ¾-inch PVC elbow to either end of each bottom support. Attach the other end of each elbow on one support to a 55-inch PVC tube. Attach the second support to the other end of the long tubes to form a rectangle.
Slide a 26-inch PVC leg into each of the four T-joints. Attach an elbow joint to the top of each leg, then place the two remaining 55-inch lengths of PVC into an elbow on either end of the stand. You now have a large rectangle base supporting two cross arms above.
Attach a 24-inch length of chain to the two hooks on the top of each shop light. Place two S-hooks over each of the top PVC cross bars and hang a shop light from each crossbar.
Place your seedlings under the shop lights, keeping the light 3 to 5 inches above the top of the plants. Adjust the height of the lights by altering which chain link is in the S-hook.
