FYI, this is now a 30 tub rack due to me cutting the top row off.
- The top row started sagging quite a bit more than I liked due to the weight of the water tub.
- The water tub itself was sagging around the 2x2s that it was resting on. It needs to sit on a flat surface.
- It is REALLY annoying to have to stand on a ladder to check the top row.
I added 2X4s that rest across the top like I originally intended (but forgot), with some old recycled particle board on top of that. I also rigged up a new, smaller water tub. I guess I'll see how this holds up now. Hopefully it works out since I'm going to have to build another rack within the next few weeks for grow-out tubs.
