OK!
I've decided I like the look of the colored "mega heavy duty" 1020 trays from Greenhouse Megastore better than the less expensive black ones. The colored ones are slightly sturdier, but the black ones will still outlast the cheap ones by many years. I have at least 5 totally unused, maybe 5 more slightly used (indoor seed starting, for just a month or two), offering for $4 each. I've been seeing the cheap ones for about $2, and I only get a couple years of use from those.
They'd also make good group "saucers" or gravel humidity trays for indoor plants.
I also have matching size clear humidity domes, the unvented ones (I poke a few holes in them for ventilation), at least 5 totally unused, also $4 each (slightly below cost for both trays and domes). I intended to order the tall ones, but the guy taking my phone order put down the regular ones, and i don't need that many.
