Some crypts may react differently. But what I did to my crypt to make go terrestial was to give it lots of moisture/humidity on the land. It does quite fine in just regular potting soil.
If your tank is not set yet and you want to get your crypt going for land already, just place it in a pot and put the pot in a zip lock bag. Spray it with water and close it. Check the next day to see if it adapted well. Only a few leaves died when I tried it.
