@Mañ'O'Green Well as you said, I'm having issues with heat and humidity in my tent with the 400w MH light even tuned down to 150w.
I'm keeping my tent door open to let some fresh air come in and it seems to be working ok for the most part, temperature overs around 77 degrees and ambient room temps is 66 degrees.
My issue is humidity, even with a small humidifier inside the tent, it stays at a constant low of 30-31. I'm afraid this will cause some issues when the seed starts growing.
I currently have a 4inch exhaust fan with the carbon filter strapped at the top and it's running quite fast, but it's not enough to keep the hot air out of the tent.
Would switching to a lower wattage LED light like the Mars Hydro TS 600 help at all?
Thanks again for your knowledge.
