When I originally introduced my Neps into a Gro-lux lighted terrarium
using 4 bulbs the new leaves were smaller and _much_ redder than the
previous leaves. When I cut down the lighting to 2 bulbs the leaves
increased in size and were much greener; the edges of the leaves are
still a bit pigmented, as well as parts of the pitchers, and the
pitchers are also bigger.
