I got some interest about how my indoor growing setup for my tropical looks, so I thought I would post here with pictures and techniques.
I grow my tropicals next to a large bay window in my dining room. I have one greenhouse and two aquariums that I use to keep the tropicals humid:

Here's a closer shot of the greenhouse. There is a light with a built in reflector on top that has one cool and one warm CFL in it. I will occasionally stick a humidifier in the greenhouse if aerial roots or the likes are needed/wanted (the humidifier can sort of be seen at the bottom right of the picture):

And here is a close up of one of the aquariums. I have a flourescent light on top and the tank is covered in plastic wrap. There is a layer of gravel at the bottom of the tank so taht the pots do not sit in leftover water. I leave the humidifier on in this tank for several hours a day:

The results I get from leaving gravel at the bottom of the tank:

And this is the other aquarium, which I use just for rooting tropical cuttings:

A shot of the hose from the humidifier going into the tank to supply humidity:

Hope this was interesting to some of you!
