There are many who have small set-ups just for crypts which are pretty neat. Some of the more rare ones are pretty hard to grow needing special requirments, but most of the common easier to find and available crypts will readily grow with no special treatment. All you need is a spare tank with a few inches of water, maybe a little pump or air stone to keep it moving, and some pots with a good nutrient substrate mix. Put a clear top on to keep it humid and your on your way Note that if you dig around you can find a wealth of information about set ups and ways to go about it.
Most plants can be grown emersed, I have found various salad and take out containers with the clear snap on lids work really well to get plants started and once you have a good amount of growth above the water you can start to crack open the lid over a week or two and slowly get them used to the room humidy.... Right now im working with some glosso in a little take out container like that. Use your imangation and dont be afriad to try something..... whats the worst that could happen? haha
