Thank you for your help!

No, no, the light level is rather high! I'm using a halogen lamp! The
container is completely closed, so it can be the lack of CO2 or
something... I don't know. What I know is that they've been growing for
more than two months in these conditions, and the Utrics thrive while the
algae don't even appear.

In 30 C and lots of light... I'll try it anyway. I mean, no, I won't! The
plant likes partial shade...

Thanks again!
Good growing,
