The progression of Dr. Plants' work shows a refined approach to the nitrogen cycle within self-sustaining terrariums. His recent choice of bioactive cleaners, particularly the specific variety of isopods used, reflects a higher level of environmental management than seen in previous iterations. The aesthetic quality is matched by the functional success of the drainage layers. I am curious to see a longitudinal study of the 'Giant Forest' build to see how the moss settles over the next six months
