Oh yeah, David, you've sure got bitten by the gardening bug, haven't you. Lots going on there, and some really nice plants coming along. What's that nice big white window box (in the helichrysum picture) doing not filled with soil and plants yet??
If I may suggest, the article on the home page about making self-watering planters out of reusable buckets would be a good one for you.
Also - and I know this is tough but - you might want to try to look for smaller-sized (when mature) plants until you get some really big containers going. Things like plumeria, goodness! they are going to need a huge planter very soon or you'll be watering all day long. I started two plumeria from cuttings last fall and one of them is already over 4ft tall and ready to open a flower. But you can get dwarf varieties that will stay on the manageable side for you, and not need a planter that weighs 100kg. and needs a dolly to move it around. Or take up your whole apartment when you need to bring them in for winter . . .
