With Jackson`s as with other montane species there are two crucial factors ...cooler temps than most other non montane species and more showering/misting sessions for longer periods. My cage is set up with one side of the cage with a cooler temperature and ample foliage so that the leaves can hold the water on them. I also have a dripper right on that side and a fogger which flows down the plant ...on the other side it is warmer with less foliage and a basking spot at 82 deg.. the middle of the cage up to the humid side must be in the range of 65 - 75 deg and a night-time drop is fine for them..remember one thing > they are originally from the mountains in Kenya which has significant rainfall...also has sun so try include that environment in your cage with possibility of space so that your cham can move around to different temps and environments....follow this link for a clearer pic...on the other hand mine likes to stay in his basking spot mostly !!
