I made a light stand out of pvc pipe. I found the idea online, just google pvc plant light stand. You can make it the size you need. I made one about 30"x26"x14" and it cost about 16 dollars.

Well of course, why didn't I think of that in the first place?

Ain't it strange? When I first looked onto a hydro project maybe 20 years ago, the lights were massively expensive and the most expensive piece of the puzzle by far. Now the light fixture is relatively speaking, the big item.

When I looked into solar, the panels were only 25% of the cost these days.
