Surely this group is quiet enough to be able to cope with such discussions;  
and in fact we need the activity.

Why not share the enthusiasm and knowledge by having the discussion 
here?

I am currently growing ( I think) Adiantum formosum from spore harvested 
more than a year ago, and I raised in this group the matter of getting the 
prothalli to produce sporophytes.

I was advised to flood the prothalli (which are now many months old) with 
water ( one person suggested dilute nutrient solution). I flooded them with 
water for about 18 hours which I thought would enable the spermatozooids to 
swim to the archegonia. Four weeks later it looks as though this might have 
worked.

I didn't use dilute nutrient solution as the prothalli are already growing on 
sterilised soil and I think there are sufficient nutrients available there to get 
into solution. Also, I do not consider that nutrient would enhance the 
swimming of the spermatozooids.
