    Default Mold in flask

    Today I did see something white on some roots of my little Asco's. Yesterday there was nothing wrong. Can this be mold? If so what should I do? Do I have to take them out of the flask? Who can help me? I don't want to loose the seedlings. The problem seems to be only on the roots that grow out of the agar.

    perhaps it is the root hairs that orchids have? do they look like little hairs? if the roots are suspended in something like the agar, it isnt uncommon for them to be bare.

    It is very difficult to see with bare eyes. The spots are very tiny. Can it be dried agar.

    Agar is usually a dark, grey colour. Could you take a pic with macro enabled?

    Just keep an eye on them, if it spreads deflask them into warm water with fungicide. And keep fingers crossed.

    I agree with Jordan it's quite common presentation to have root hairs, as long as the seedling in the flask doesn't change the color and melts not to worry about it well the root hairs may mimic the fungal infection at one point.

    They still look fine. The biggest spot Is hardly visible any more. The other spot is so tiny you hardly notice it at all. The agar is still clean.
