The great 2024 wicking bucket/pot experiments

[21hens-incharge]

I think my overflow hole is either 1/2 or 3/4 inch. It just needs to be big enough to not get clogged. I agree that 1/4 inch is probably too small.



IMHO, one overflow hole is enough as long as it does not get clogged. FWIW, I have never had any of my drain holes clog up. But I am sure I used either a 1/2 or 3/4 inch overflow hole in my sub-irrigated planters.

Also, my planters' drain holes do not have direct contact with the potting soil. There is a barrier between the potting soil and the water reservoir, so that also greatly reduces the chances of any clogs from soil debris. It is really only water in the reservoir that would ever drain out.

I thought we had that barrier in place well enough. It is possible that when filling that ones soil section some got between the trough and the liner.

Just one of those things to pay attention to.
