As I have been reading many of the threads talked about humidity levels during the flower stage, but what about the veg stage. Currently I am in veg stage of day four with Sour Diesel clones. Currently it is 28% humidity and 87 degrees. I added a few open containers of water to the area and I also set up a rotating fan, I also have a small heater in the room. Should I get a humidifier? Thanks all.
