russrahlanswered grow question 4 years ago That is a bit high for temps, you need to get more ventilation going to get the hot air out and cooler air in. Turning you light off to cool it now and then is only a temp fix and will come to bite you in the butt sooner or later when you forget or are away and not able too. I run air conditioners in my bigger tents to combats this exact thing. Lol I got two 4’x8’ tents beside each other in a 14’x10’ room, both running 1000w HPS and the heat is unreal without air conditioning. Lol without AC you definitely need more air flow. Hope this help, cheers 💨
