Tiny pots what to grow?

Morning all,

I’ve got 12 of these tiny pots left over and thought I could use them nailed to my garden fence as tiny pots. Yes they are TINY.

I am aware they will need lots of watering due to lack of retention (I do have some water granuals to add to soil?). I also know that not a lot will grow due to lack of space BUT…

I’m up for a little experiment. I have nothing to loose as I have loads of other plants and seedlings growing atm.

Thinking about what I already have that could work: trailing lobelia, geraniums, nasturtiums. Any more thought? Happy to go and buy seed packets.

Can’t wait to hear your positive ideas and enthusiastic replies! 🫣
