need recs for best hanging houseplant base/water catcher
for my hanging plants, i need a source for a sturdy water catching dish to go under the pot. (i am having a brain spasm, b/c i can't remember what those things are called.) ideally, the dish needs to be rigid (so that it doesn't buckle under the weight of the pot) and deep (so it can hold more water).
for those of you who may comment about having my plants in standing water: i typically drain off the excess water later in the day. i need the water dish because some of my plants immediately drain most of the water out and then re-absorb it over the next several hours.
thanks in advance for any vendor recommendations!
