She was chasing humidity. The tube dried out faster than I expected, and she kept moving to the wet end, then back again. It was stressful for her and honestly stressful for me too.\u003c\/p\u003e\n\u003cp\u003eThat experience is exactly why I pay attention to founding tube design now. This bamboo nest solves the problem at the material level: the inner core is cast from gypsum mixed with fine sand, the same combination used in lab-grade formicarium panels. Gypsum absorbs and releases moisture slowly, so the humidity gradient inside the tube stays consistent for days after a single water top-up. The bamboo outer shell adds a second layer of insulation and blocks the kind of sudden light exposure that sends a founding queen into a panic.\u003c\/p\u003e\n\u003cp\u003eThe layered construction also means you can stack or connect multiple tubes as the colony grows, building a modular founding setup without buying a whole new formicarium. Five diameter options, from 15 mm up to 30 mm, cover everything from tiny \u003cem\u003eTemnothorax\u003c\/em\u003e species to larger \u003cem\u003eCamponotus\u003c\/em\u003e queens (carpenter ants,
