I'm planning to set up a nano-vivarium to grow moss and ferns indoor like shown in the picture below.
My question is what kind of light is best or which lamps should I use? I don't have any experience with indoor-growing moss yet.
You can use just about any light source but each has it's consequences for your design:
With any indoor container the following issues will arise:
If money is no object and the look and aesthetics is important go for xenon. If cost is important use fluorescent with the best bulbs you can buy.
