Soak a seed-start mix with boiling water to kill parasites. Allow to drain and cool for about an hour. Tap the spores onto the surface of the growing mix. Cover the pots with plastic, or place in a clear plastic bag. Place in a well lit window or under grow lights, but not in direct sunlight. Water from a bottom tray as to not disturb the spores. Temperature 20-22C, 68-72F. The ferns will start to germinate in a few weeks, though could take a few months to form little plants. Patience is required, though they are well worth the wait!
