I have a 10ltr carboy (glass jar) that i want to make into a terrarium for the sun room, what plants would you reccomend?
A terrarium is not suitable for a very sunny position. It can take some sunshine but not much as the plants get too hot. and there is excessive condensation on the inside.
Good light but not direct sunshine is what you want. Use small ferns, selaginella, polka dot plant, peperomia, maranta and baby’s tears, for example.
