I have my turbokloner placed in a 3'x3'x6' tent lying on it's side down, and use a small 4 flouro tubes low profile hanging inside above it about 16'' from the top of the turbokloner. I keep the door flapped unzipped.. I also don't have a humidity dome and my temps are 76F-81F 40-55% humidity, but it's slightly higher inside the tent even though the door is not zipped. I also sprayed my mothers with clonex spray and the clones themselves once they were placed into the cloner.. says it stimulates roots but I can't say it's a huge factor because I've had success without using it also.
