European Cym.
 

Dear friends, i bought three cyms came from Holand, these plants are in wood bark medium, In karachi maximum tempreture is 45 centigrade and average temp is 38 in summer and humidity is 50%.i have one cym, came from china is with me since one year and in good condition, i need the following answers.
1- shall i change the medium and mix charcoal and pumes stone with bark wood due to high humidity.

2- Instead of keeping these cym in green shed, where temp is some time 38, keep them in complete shed, where money plants are.
or can take them to in side house, where tempretre is less.
the first photo is holand cym and second one is chinies
