Hi Eric,
I'm not certain, nor can I find this on the Web,
but I seem to remember that a few seeds were planted in the Moon dust, sometime after its return. The findings were, that the seeds actually germinated stronger and better than control seeds in sterilised Earth soil.

You could look for growing using low pressure, which is also quite interesting.
