Hi
@urbangroove! I can see your night temp is pretty cold, whereas your day temp is quite hot, the gap is impressive! It makes me think that your setup generates too much heat, mostly because of your lamp, and also a poor airflow. How do you extract the air out of the tent? Do you have an exctractor? If yes, is it connected to a thermostat? What are the settings for the thermostat? I guess the room where you did put the tent has a decent temp, but the air remains captive inside your tent, so try to improve your airflow, and put a tiny fan blowing a continuous breeze onto your lamp in order to cool it down. Another option would be to put some iced water bottles in the tent every morning, but this is time consuming and lasts only a few hours. You should also increase your relative humidity, in veg the best is around 65-75%. Finally, consider going with LED next time, the new models are pretty impressive, my QB setup generates almost no heat at all. Hope this will help, keep us up-to-date and happy growing 👊
