I have 3 flasks of my own cross and decided to deflask 1. Advice I have received is only to deflask when leaf growth is about 2-3 inches but I thought I would experiment.
Mix is organic potting soil ( 8 parts ), seedling bark mix ( 4 parts ), perlite and charcoal ( 2 parts each ).
I obtained roughly 20 corms from the flask - some pea sized, some baby-toe sized and some in-between. New growth was evident on about 5.
There are about 5 or 6 corms in the pot in the photo.
I will take photos when I deflask the other 2 flasks but in the meantime will update as growth appears in these pots. I have watered from the bottom - pots are standing in about 1/2 in of water.
They are under lights. I am nervous about fungus as these are prone and I have never used potting soil in a mix before. I have also potted up the parent/s in a similar mix.
the multi-growth evident in bottom right of photo is interesting as it had a long root, no corm. I don't expect it to survive outside of the flask, but we'll see.
