Your Cephalotus "Hummer's Giant" in a 75% silica sand / 25% peat mix has been static for two years—healthy ¼" pitchers but no growth. Morning sun, cooled water tray, highland greenhouse conditions.
The issue: lack of prey. Cephalotus is primarily an ant-catcher. In a confined greenhouse, it may not catch enough insects to fuel growth.
Also note: Cephalotus often has a brief winter slowdown. Since you're in the Southern Hemisphere heading into winter, reduced growth is normal now. Pot up to 5–6" tall pot with long-fiber NZ sphagnum + perlite for better root run. Feed, wait a month, and watch for a growth surge.
