Plant Pot with Saucer

Print the saucer with the bottom on the print bed for best results. It may be easier to print the pot upside down, but if you do, there is a risk of spaghetti-ing filament when it does the slots.

I'm not sure what the difference in layer height will make(except time), but I think that if you use a 1mm nozzle and a high layer height there will be more bacteria growth and microorganisms in the soil, which could be good or bad, depending on the situation. If you use a high layer height for the saucer, it may be prone to mold growth. If you don't want to run any risks of things growing in the layer grooves, you can give it a coat of resin.
