I have an empty 55 gallon aquarium sitting in the garage and I've just discovered terrariums while surfing the web. They seem really cool and since I like bonsai, I was wondering if I could plant 2 ficus bonsai opposite each other in the aquarium? I have a plan to make a "miniature pond" in the middle to help with humidity. I would also like to make the soil level at 1/3 of the tank in hopes the more soil the larger the trunk could become, with proper pruning of the roots of course. What soil mixture would you use for a ficus in a terrarium? Would there need to be a space between the bottom and soil line for proper drainage to prevent rot? I would like to get artificial light as well. Any suggestions on what type of lights to use and how often? Could a ficus thrive under artificial lighting if done properly? Does a ficus need dormancy? And finally, are there any "tropical" moss specie I could find to cover the soil. I think it would look great with moss added. I know this is a lot of questions but I've never had a ficus or a terrarium. Thanks for any and all info.
