Okay, I've looked and looked for something I can put 4" round plastic pots in to water, but have come up with nothing. I'm looking for something like the following:
I found these at a store called the Christmas Tree Shops, which is only located in the East. But, I've seen similar at dollar stores locally. I used them for winter sowing, but also used them for when I needed to transplant from styrofoam cups to 4" pots. They have plenty of holes in the bottom, just like you see in the sides.
But what I'm actually looking for is a container like the water tray pictured in my original post ... something without holes in the bottom ... that way I can water from the bottom *and* have a nice handy container for picking up the plants and taking them outdoors to harden off before transplanting.
I can get the exact 'watering tray' shown above, but only in lots of something like 2,850, which is WAY WAY more than I need.
I suppose I *could* just buy any ol' container to put the pots in, but the ones pictured above sure look convenient.
