... here's a good idea for how to start your seeds for the balcony or patch-of-patio, or for pot-tenders, when you go away and your plants need watering.
I can picture doing this with some of the dreaded plastic storage containers that are available to buy, out there. I don't have a hoard of plastic containers around the house...
And wouldn't the principles be wonderful for making the same design out of teracotta, say? or some recycled something-or-other. I always wonder about the effects of plastics on growing plants....That (terracotta)I can really "dig". :-)
