Project Nucleus was launched to facilitate the creation of the miniature planets I create within glass. Terrarium-building has always been a passion of mine, but it has a secret, and I reveal that secret today. In this episode, we create a special enclosure from which I intended to culture populations of soil creatures and biota for propagation into my terrariums. We also take a close look at the amazing symbioses happening at the soil level within one of my established ant colonies (The Golden Empire). It’s a whole other world within the soils!
