Plantariums are life-giving ecosystems in which seeds germinate. The colorful gel's transparency makes the seedling visible throughout the entire germination and growth process. Plantariums work as a mini-greenhouse: after the seeds are germinated in a dark room, they are moved to a bright spot so the seedlings can thrive. When the seedlings reach the top of the container, the plant can be transplanted into soil to complete its growth. Complete instructions are enclosed. The Garden Lab Kit includes three containers (4.25'' x 1.75'' x 1'' each) and has seeds for three different plants, peat and pots for transplanting.
