So, what's the answer Or more specifically, how do you do it inside (a terrarium or not)?
A larger pot may allow/support/result in even more foliar growth. (I make sure to provide plenty of aeration in the soil [e.g., #3 perlite], esp. with larger pots. [I also only use net pots.])5 inch pot? I own those, they are quite small for a 3 foot large plant. I think the pot is way too small, but probably not the reason for the flowering.
