# Hi all, When growing your Corms, do you keep them open to the air or…

_Posted by MudSkipper Jnr on 2024-05-13_

Hi all,  
When growing your Corms, do you keep them open to the air or covered to retain moisture? The ones I had covered with a grow dome were showing signs of mold so I took the lids off \& wiped away the mold. Since then I’ve seen no change or progress.

All guidance appreciated 🤗

I have tried moss and it did the same thing. However when I did fluval stratum I have zero mold regardless if the plant is open to the atmosphere or not. With that said they do better when they have high humidity! If I get a lot of Croms from a plant then I usually put it in a food storage container and close the lid. About every 5-7 days I open the container then close it up again.
