Terrarium Design Add-On

POS add-on for finished terrariums. Ring one design level in addition to the vessel base.

Simple: about 20 minutes of design/build time; straightforward planting with minimal hardscape. Classic: about 1 hour of design/build time; layered sand/substrate, elevation changes, paths, or a more developed composition. Specialty / Architectural: about 2 hours total design/build time; pre-built driftwood arches, assembled stone/wood structures, or other labor-intensive architectural features. Use this tier for highly finished, design-forward statement builds rather than every piece that happens to take extra time.
