Thanks. I don't let plants sit in that depth of water for long. I just like the margin of safety against overflow. And I had trouble handling shallow trays. One wave and it's all over. (But, I bought a FlowStix battery operated pump to suck the runoff out of the saucers. I don't lift them anymore.).I love your trays!
It's hard to cut a circle around a bucket. I put marks around the circumference. Then used masking tape to connect the marks, creating a visible line. Using a hacksaw, I cut lightly all the way around. Then a little deeper all the way around. Finally started cutting through. You have to be careful not to cut too deep too fast or the blade veers off track.
I feel another blog entry coming on.
