I went to my local hydroponics shop to look at 1020 trays and they are much smaller than expected, and do not fit the small 6 pack thingies (6x2.5" cells) or the 4" square pots very nicely. They really seem to be only designed for the smaller cell inserts or simply using them for free-form sowing.
I have a few of these open trays that the interior measures 16"x16", they take 16 of the 4" square pots or 6 of the 6-packs.
After some internet searching, I cannot seem to find any that are solid to catch the drip. Same for the 4" round pot tray. Do they exist? What are these? I'll try calling the nurseries around me to see what these are, but they won't open for a few more hours and I thought it'd be interesting to share for sake of discussion. I suppose I could cut up a garbage bag and line the inside, but, meh. Maybe I'll see if the restaurant supply store has a low-walled bussing tray or something.
