Fern Propagation

So I am trying my hand at growing ferns from spore. What I have learned so far is that it is a very slow process. These two trays of ghost fern spore and maiden hair have been growing since late August and have only developed a handful of mature gametophytes. The maiden hair spores were sowed on the thick side.
The whole process is definitely a waiting game. Has anyone else had success at growing their own fern from spore?
