KMG reminds me of something else... you are basically creating a micro climate for your snake a little portion of Africa in your home. Plant choice needs to account for requirements of that plant and the two need to over lap. KMG sounds like one of the plant choices is an arrowhead or some sort. If that is the case, they usually need to be in water marsh areas and although likely do will hydroponically. They may not survive just placed in an enclosure , if this is correct, the roots need to be under water all the time. Not really a semi arid tropical plant.
