Can as an alternative container?
 

I have a lot of these cute cans I bought from the Japanese markets. Do you think I can reuse them as container for mini orchids? Not permanently of course. It just feel like a miss opportunity to not make the most out of these design haha. :biggrin:

I've wondered about using marine varnish on cans after the holes are drilled.

If the cans are aluminum, then they likely would not have a corrosion problem after the painted surface is breached.

Food safe is plant safe, and then some. Just be careful about sharp edges when cutting.
