How To Make A DIY Indoor Grow Light

Step 1. Making The Grow Light Side Ends

Using the curve in your metal duct pipe, prepare the scrap plywood to close the ends of your grow light frame. Hammer first, two finishing nails near the end of the plywood about 6 inches apart to get the cutline for the plywood.

Hook the pipe to the nails and do the cut line using a pencil then cut with a jigsaw.


Step 2: Cutting Holes Through The Wood Pieces

Using a jigsaw, cut the first end piece and make it as a template for the second cut. If you're using a bulb with a large base, mounting it outside the fixture will prevent the base from blocking light for the plants.

You can cut 3 1/2in holes in the center of the plywood using a jigsaw. This is for the bulbs which will be further explained as you go through these instructions.


Step 3: Grow Light Parts Assembly

Wrap the 2 feet metal duct pipe on the contour of the plywood, fashioned to make the ends of the light fixture. Then attach and secure the metal duct pipe to the plywood with screws.


Step 4. Attaching Hook Screws

Now attach the hook screws to the center of both the ends of the light fixture. You can attach a rope or a chain to the hook to hang your DIY indoor grow light.


Step 5: Build The Structure For Mounting Light Bulb

It would be ideal to mount the base of your bulb outside your light fixture so they don't block the light. Now that you've drilled the holes for your light bulb, use scraps or pieces of the plywood you used to build the structure on either end of the light fixture.

Use 2 pieces of 2 x 4 scrap wood to build a structure outside the end fixture so you can mount the bulb holder outside. Cut the 2 x 4 scrap wood to 3 and 1/2 inches and attach them with 1 1/2 deck screws.


Step 6. Assembling Structure For Light Bulbs

Now, cut a piece of plywood to bridge the 2 x 4s, then cut the plywood spacers to allow you to mount the lamp holders without pinching the wiring. Attach the plywood pieces to the 2 x 4s with deck screws.


Step 7: Bulb Holder Installation

Use an 8 feet cord or electric wire to wire the lamp holder. Cut about 3 feet at the end of the cord, then strip both ends and use it to wire the two lamp holders together. Then wire the piece of cord with the plug to one of the lamp holders. You may also refer to the instructions that come with the wire cord and the lamp holder.


Step 8. Wiring Installation

Lastly, attach the lamp holder using screws available with it or ones available around your house. Then keep the cord that connects the two bulbs outside the fixture.
