Hell yeah. I'd like to try grow large sunflowers at some point for the seeds but there's nowhere really good to put them for us. We can get strong winds over summer and everywhere sheltered I usually have taken up by plants I value more like determinate tomatoes and peppers.
Currently winter here in the southern hemisphere, pretty far south so can get some frosts. Our family set up a small greenhouse last spring or so though which I have a fair bit growing in - from the first pic going clockwise from bottom left have -
~ a couple trays of old spinach plants which have been going since late summer (and some oxalis mixed in which is the red colour - a weed but still edible)
~ minutina (looks like grass)
~ lamb's lettuce
~ red variety of mizuna in the middle
~ few ~30L pots in top right containing broccoli with perpetual/regular spinach surrounding
~ some garlic chives in the 2 square green pots (planted these in autumn which don't think is the right time, but they're surviving and seem to be slow growing anyway so will see how they go)
~ beans/peas in the pots with the mesh (there's about 8 or so of those pots in total but most aren't shown in the pics)
With the beans/peas grew them using that style of mesh last year OK, although the pot circumference was larger (30L pot vs 15L pot). They'll probably get all tangled up in the middle eventually as just have the plants in a circle around the outside of the pot, but I'll just see how they end up being with pests/harvesting in early spring.
Apologies for potato quality of pics, currently travelling around so these pics are just what my mum sent me recently by txt message so they're super compressed.
I assume you would be based in the subtropics? There's a lot of stuff like tamarillos and watermelons that would be cool to grow which aren't really feasible down here due to the climate.
