38V is a variant of the original 38 series where a large glass sphere is blown with a multitude of haphazard interior cavities, which intersect and collide in unpredictable ways. 38V is smaller and lighter. The are 4-6 cavities blown within each sphere, 3 of which house light sources, while the remaining are deep enough to house plants. Any kind of plants can be used for this model, but Bocci usually recommends using cacti, succulents and air plants.
