How can you manage having a terrarium with only 4 bulbs for lighting? Does the
terrarium recieve natural light? How tall are these set-ups?

In my experience four bulbs will be sufficient lighting if it's about 1 to 1.5
feet away and the plants are directly under the lights. Any farther and the
plants seem to suffer. I try to get the strongest (highest lux) bulbs that I
can find. It's usually around 3050lux each.
