How to support eggcrate (plastic grid)?

19 years ago

For drainage and humidity, I place pots on top of eggcrate, a plastic grid about 3/8" thick that sits inside the plant tray. The only problem is that it gets mucky after a while and is time-consuming to clean. (I don't own a dishwasher, which might simplify the job.)

I'm thinking that if I support the corners of the eggcrate to keep it out of standing water, it will stay much cleaner. One-inch slices of PVC pipe is the first thing that comes to mind. Have you tried anything like this, and what did you use for supports?

So did you come up with anything? I'd think that whatever is supporting the eggcrate would then need washing! And I have heavy pots, I don't think the eggcrate would support their weight very well.

Well, Indoor Garden Supplies sells supports that are just pre-cut slices of PVC pipe. They're more convenient than hand-cutting because they're uniform, but also more expensive. Six of them in a 10"Ã20" tray would support even heavy pots, and they are much easier to clean than eggcrate ... but it doesn't really take that long to scrub off eggcrate with a stiff-bristled laundry brush.

I guess from the lack of response that most people just use one or two layers of eggcrate.
