GC Tangerine Dream Auto First Grow Ever

1/31/20 - Seeing a little growth every day. No idea what I'm doing with watering yet. I haven't watered for 3-4 days and soil still seems moist about an inch down from surface. I have also been misting top of soil and plant with water the last 3 days...mainly because humidity is so low. I'll likely be picking up a small ultrasonic humidifier in the next few days to see if I can improve things. Watered 32oz. (6.6Ph) today. 2/2/20 - Still growing :) I tried a small humidifier and it did work pretty well but it was not big enough. Only got humidity up to 38% and ran dry in 4 hours. I'll be returning it for a bigger one. I'm also a little confused about venting the tent. I have small flaps at base of tent I opened two of them by tenting the bottom of flap slightly, making an opening where direct light can't get in but air can. I think this really hurts my heating and humidity control efforts but plant needs fresh CO2, right? I'm running the vent fan (configured as exhaust) at about 33% speed with the carbon filter inside the tent for extraction. Any suggestions or explanations for how to set vent flaps? 2/3/20 - Watered 16oz. I also closed one of two vent flaps and lowered fan speed to minimum. Per advice received from my question, I am puzzled by the answer to close all the vents with the vent fan running. Not much change noted on temperature or humidity after a couple hours. Still waiting for replacement humidifier. 2/4/20 - Got my new humidifier. This one has built in humidistat and 1 gallon tank. Filled with distilled water and put in tent. Seems to be working well. 2/6/20 - Humidifier working great. Plant is doing great! (or so it appears to me) Starting to notice a slight odor now in the tent when I open it. Still trying to get a handle on watering. Soil still seems moist. on top because of the humidifier?
