8 Ball Kush...First grow (medicinal use)

First time grow, growing this to turn in to oil as I have recently been diagnosed with stage 4 lung cancer. 1st week seems to be going OK, only thing I'm struggling with is keeping the temp down and the humidity up, im growing in a small tent 60x120x150cm so its hard to keep temps down. I've just bought a humidifier so hopefully this will solve the humidity levels, The plants seem to be happy and growing fast.
