What is the best type of bonsai to grow indoor?

I have 3 juniper mound bonsai that i cut and tended my self.


one ended up dying because it was stilll young but i cut the roots too much.





But this older stronger one that i happen to find i didnt touch the roots and its looks really healthy.





But what is the best for indoor.





And also what lights could be used as a alternative instead of sunlight?





I need deep details. |||Junipers are outdoor plants generally.You can see care instructions on this site.

You casn see examples of indoor and outdoor plants on it.|||There is no one "best" for indoors. Each tree has it's own requirements and depending on the conditions you have available (light, heat, water), the amount of time you have to spend, and what your goals are (fast growth, big tree, tiny tree, etc.) will help you figure which indoor tree will be best for you.





Here are some popular choices for indoor bonsai that are relatively easy to grow.


Ficus - benjamana, retusa, burt davii


Serissa


Schefflera


Fukien Tea


Natal Plum


Portulacaria


They all may deserve a look.





As for an artificial sunlight source, there are fluorescent "grow lights" available at most home stores. Another good source for smaller lights is an aquarium supply store. Look for florescent tubes designed form a planted tropical aquarium.
