Papa_Tanswered grow question 3 years ago Try adding a humidifier to your tent. A cool mist one.
I have a 2x4 veg tent and when I forget to fill it the temperature rises in my tent. When I fill it back up it drops the temperature a bit. Maybe add an oscillating fan too. 86 is a bit hot. 77 would be more ideal.
I also have a 4x4 flower tent and I can’t keep the doors shut when the lights are on. Also maybe try having it more open.
Either that or you add an expensive AC unit.
Hope that helps.
