FAQ
Does it need CO2?
CO2 is strongly recommended. While Eriocaulon Vietnam can survive without CO2 under strong lighting, it will not thrive or reach its full potential.
What substrate works best?
Nutrient-rich aquasoil is ideal. Inert substrates require root tabs to support this heavy root feeder.
How do I plant it?
Remove from the pot, carefully separate the rock wool from the roots, and bury just the roots in the substrate — leaving the crown exposed.
