Mushroom inflation

[Ali-F]

Hi,

I am not sure why these inflate when the light is on. They became like white small, medium and large size balloon. They are less attractive this way, I like them more when deflated.

Any particular reason?

It's just a normal function for the mushroom to inflate/deflate throughout the day. Sometimes rhodactis will develop permanent vesicles like that.
