Dang those pitchers are big! You should just make a grow room from the start of the door(left) all the way to the right wall.:grinno: For the droseras, I think as long as you acclimate them to lower humidity conditions, they shouldn't have any problem.
Pony, My raffs are in a terrarium with humidity around 80% all the time. They are lowlanders and need high humidity and warmer conditions. hope it helps.
