Adjusting My DIY Grow Lights

Adjusting My DIY Grow Lights

Those of you who have been reading my blog for a while, know that I built my own PVC grow light stand last year. The goal was to do it as inexpensively as possible. So I made use of several shop lights I had acquired over the past few years and spent a whopping $16 on PVC pipe. You can read the original story by clicking this link: DIY Grow Light Stand.

But I quickly discovered something that I didn’t like about this design. All of the lights were attached to the same cross bar. And though the cross bar itself could be raised or lowered, depending up on what the seedlings needed in the way of “sunlight”, the individual shop lights were always all at the same level.

That didn’t work for me. As you can see in the photo above, my tomato plants are growing quickly and need the light source to be raised higher, while my chamomile and lettuce starts need the lights to be much closer.

Adjusting Grow LightsMy solution was to employ some chain a few hooks and scrap wood blocks to make each of the grow lights independently adjustable. You remember that children’s song..the knee bone’s attached to the shin bone…the shin bone’s attached to the ankle bone? Well I used that as an inspiration for my setup.

I screwed 4 hooks into 4 wooden blocks, and then draped a 4-foot length of chain over the existing cross bar. Then I used the clamps on the grow lights to “attach” them to the wooden blocks. The result is that I can raise and lower each individual light simply by unhooking the wooden block and recooking at a different point on the chain. It’s a simple, elegant solution that honestly took about 10 minutes to put together.

What are your solutions for catering to the needs of seedlings that germinate and grow at different rates? I’d love to hear from you!
