I have experience with them outside. They're pretty hardy and if you over water, it's not too big of a deal but don't do that too often. Put them in soil that drains well. I have a plant that same size as jason.
The pothos will be fine, but the jade - bad idea! I grow a lot of succulents, and jades are adapted to a very dry environment. They would not respond well to the very high humidity and most likely would succumb pretty quickly. Just like a fern would not survive in a desert, these would not survive in a very humid area.
Actually ive been using jade plants in bottle garden terrariums for a long time and they do pretty good! Also I've root jade in water and just left them in water for well over a year and they adapt fine! They can take a lot of over and underwating and I think they would do just fine in your terrarium.
Yep! I have one. I'll try to get a picture of it in the next few days.
To be honest, it's more of a baby jade than a full-blown bonsai that was carefully planned and trimmed. Started it from a pinched leaf from my big jade plant, and it has taken over two years to reach a height of 3 inches. It's in a tiny (~1.5 inch diameter) bonsai pot.
F22 - you could try growing some crypts emersed. I've had good luck with C. beckettii. You might be able to get away with some air plants as long as they're above the waterline and have good air circulation. They need some humidity but also the chance to dry a bit so they don't rot.
