The case I built, although not a true wardian case, might serve as a useful 
comparison. I built a 3 foot high case with wood sides and clear heavy 
plastic for the front and back. The case fit over 2 cat litter boxes 
where I put the plants sitting in water. This made the case about a metre 
wide. My lighting consisted of two 2' long workshop flourescent light 
fixtures with Vita Lights for a total of 4 bulbs. The problems I 
had were 1) the lighting was insufficient for the smaller plants 2) the 
lighting was to weak for the Sarracenia (they grew thin weak pitchers 
even with the addition of one extra side light) 3) the ventilation was 
inadequate even with the plastic raised to expose a 4" long slit in the 
front 4) the humidity was inadequate. Contrary to what I've read about 
sitting plants over trays of water I have yet to see any verifiable 
difference in humidity. The growing box had the same humidity (35-40%) as 
the house humidity when checked with a hygrometer. Lava rock added to the 
bottom made little difference and rapidly mineralized. 5) the temperature 
was too hot and killed off my Darlingtonia and damaged several of the 
Sarracenia during the summer. This has been my only experience and is 
serving to guide my future growing area that I will be building in the 
basement. I hope this is helpful.
