I am running a 600w HPS in a 4x4x6.5h with a 440 CFM inline fan pushing air into the tent with vent holes at the bottom for airflow to blow out (I hear this helps with pests)... however, since this is my first tent, I don't have any idea how the temperature/humidity is going to react when the bulb is fired up. I have a thermometer/hydrometer but just for monitoring... I will need to make the adjustments myself to make sure that the temp stays where it should. Do the inline fans that you buy have controllers for speed so you can adjust that? If not, then I am out of ideas.. I hear that I should use about 78 degrees during veg and 82 during flower, the entire time with a 10 degree temperature drop when she is not getting any light. Dark periods also worry me when it comes to keeping the environment where I want it because now I won't have a heat source, but I plan to let the vent run 24/7, so will it get too cold?
