Looks pretty good for a balcony, pretty much what I used to grow when I lived in a flat a few years back with a very sunny balcony.
Does the wind affect the plants? I found I had to get some shielding to protect mine, just one of those roll-up wooden slat things.
I was also glad I got on with my downstairs neighbour very well - the balcony could get quite muddy after heave rain, with all the slop from the plant trays
Some of that would always end up down below.
Thinking about it I guess a little gravel in the bottom of my troughs would have sorted that.
One year I even went as far as climbing green beans and cucumbers, I got a bit obsessed with maximising the space.
The mushrooms look pretty exciting!
We actually got some pretty crazy wind a few weeks ago that lasted for about three days and I was really worried they would break but everything seemed fine. I thought the green beans would get taller but I think they might not be the climbing ones and may have reached max height, I was kind of hoping they'd go up and over the railing!
Well I'm glad they held up, it looks to me like you've got the dwarf variety, but they look and taste the same as the climbing, not quite as cool visually though!
