Need advice on transferring from water culture to S/H

[camille1585]

I put a rootless and leafless Den in water culture in march, and now, about 6 months later there are plenty of new growths and nice roots. But it seems that it has reached the max amount of time to stay in the water, as some of the growths aren’t looking as nice and there’s a bit of mold attacking a cane.

I would like to transfer this plant to S/H since it is used to water, but do I still need to wait for new root growth before transferring? Anyone have experience with this type of transfer? After managing to save this little orchid (one of my favorites) I would hate to lose it due to a silly mistake!
