Massive newbie alert here!
So, I've always been keen to get into bonsai, years ago I had a little Port Jackson Fig which I loved, but it unfortunately passed away due to teenage years resulting in neglect

So, I have this glass bowl which I've been thinking about turning into some sort of little garden but couldn't decide what sort to make! Succulents, marginals, leafy tropicals... I figured that most would quickly outgrow the bowl (except the succulents of course) then had a crazy idea today... bonsai! So here I am, procrastinating and avoiding doing study work and investigating this line of thought... I haven't found much at all about using a glass bowl, I'm not sure if this is because it's not possible, or just not traditional...

So, my question at this point is; is it possible to grow a tropical bonsai indoors in this glass bowl? I'm thinking another Port Jackson Fig... I have quite an affinity for those guys

I would layer it the same as any plant, using pebbles in the bottom covered by mesh, then possibly activated charcoal? (thoughts? I've not done this before but have seen it recommended several times for regular plants), potting mix to be planted in, then small gravel /moss on top.
Thoughts?
