Sounds fine. Plants can be grown in a lot of different conditions. The conditions your swords are in are not optimal, but you can clearly grow them just fine. Not every plant has to be kept in unlimiting conditions to grow and look nice. If you are happy with the way they are growing and the way they look then there is no reason to change anything.
The crispiness you mention is a sign that they are on the lower edge of their growing parameters (probably lighting). Most swords do not feel crispy, they are usually pretty flexible and tough except for the stems which are somewhat brittle. Again, this is not necessarily a big problem unless it gets to the point were the plant disintegrates with a touch.
