Be very careful when exposing a terrarium to sunlight - it is very
easy to cook your plants.
I suggest that you use Gro-Lux Wide Spectrum instead of standard
Gro-Lux tubes - they will produce higher intensity light for a
longer period before going bad, and they work better when
supplementing cool-whites (which will soon be obsolete, as they are
not efficient enough). By the way, soon it will be necessary to use
a special disposal process for getting rid of your old fluorescent
tubes, because of the mercury in them (all fluorescents and halides
are mercury-vapor devices, made by introducing a small amount of
mercury into a vacuum system).
