Build a Plant Grow Box

Difficulty: Intermediate


We’re sharing lots of great ideas to extend the growing season in our stretch gardening series. With this build-it-yourself grow box, you can enjoy some greenery indoors even when the outdoor temperatures drop. The fluorescent bulb will provide enough light for many common houseplants. Keep the plant trimmed so the leaves don’t touch it.

Thanks to Home Depot Associate Christine Partin for designing and making our project.

Step 1

Cut a 45 degree angle at one end of the board. You will want to do this about 2″ from the end. Next, measure 13″ from the outside corner and mark with your pencil. On that mark, cut a 45 degree angle. Measure another 13″ from the outside angle and cut a 45 degree angle. Repeat until you have 4 boards cut. You should wind up with four pieces that measure 13″ from the outside angle.

Step 2

This is how each board should look with the angles.

Step 3

Sand the edges.

Step 4

Attach the light to the shorter side of one of the boards. After the light is attached, make a 1″ hole for the cord with the wood borer.

Step 5

Glue the corners together with the wood glue, and then nail the corners together with the finishing nails. We used 4 nails per corner.

Step 6

Optional: Draw a design on the wood with a pencil. Then use the wood burning tool to burn the design into the wood. Always use the utmost caution when working with a wood burner. It gets extremely hot. Lastly, stain or paint the piece. We used Varathane “Special Walnut” wood stain. Pot up your plant and place it in the box. Remember that plants need a daily period of darkness, so avoid keeping the light on all the time. If desired, use a timer to turn the light on and off at scheduled times.

If you’re looking for a low maintenance houseplant to grow, try a peperomia, philodendron, spider plant, English ivy, or golden pothos. Cut off any trailing stems, as needed, to maintain the size of your plant.
