Default Flask Contamination FYI

Did you know........

Always keep your flasks in a clean area away from your orchids. Dust mites can enter your flasks through any vents and cause fungal contamination. This will show as a white layer on the medium. The fungus may cause all the seedlings to die.

Sadly, all the C. dowiana seedling did not survive the fungus attack - despite my most intense efforts.

Even daily flask checks sometimes are not enough.

This is a hard lesson to learn. Looks to me like you might have moved some of the seedlings out earlier (I have 20/20 hindsight, by the way )

I wish! I would have hundreds of them! That hobby flask was a purchase from a vendor at a Canadian Orchid Congress show and I did not notice that the container had a hairline crack.

C. dowiana is one plant that I am completely captivated with. Plant availability and cultural success has proved to be very elusive for me. Fortunately I recently received a larger plant from Ecuador that adusting well in my conditions.
