if you can provide some pics it would help. Are the green patches on the
peat/sand mixture or on the containers?

This was my very first attempt on treeferns, it took over a year (think
the spore where old or not ideal soil/humidity) but they sprouted.
During this long time I was more than once nearly to throw the whole
thing in the litter. God thanks I didn't do it! ;-)
I also noticed that not every mold *is* mold. Sorry, candy floss I
don't know. Google neither :
PS. Don't be afraid of german! Use english wherever you want!
