I would like to know what are the best conditions to grow Pistia 
stratiotes. So far, I put it in a jar with some soil and gravel at 
the bottom and about 5cm/2in. of water. The jar is on the window 
sill (at room temp). Does is need higher humidity (i.e. should I 
cover the jar) or higher temp? 

The reason I put  it in a jar is that I didn't have much luck keeping 
it alive in an aquarium before. I hope direct sunlight might be
