Dear Max,
you must give so many water into the formicarium, that the last room get water, you will see it, if you look on the side into the basin.
If you put wild grass into the basin, you must be careful with mildew and mites.

Thank Martin, actually i spray water on the surface one day yes one day not, because i have seen that the workers use loam to reduce opening of the t tube and the loam too wet not function well, the problem that i have with water tube is that not give water uniformly , it floods some area near the surface and leaves dry some deep zones... I can try something to obviate this problem but for now i have not resolved yet.
Bye
Thanks
Max
