I've been reading on different forums. Everybody has their own opinions. People arguing 85° too hot in grow room. NoT. I run my vegetation 85°, humidity is about 60 ,58%. No problems. So why are people telling young growers, that you need to bring your temperature down. If you go past 90, well, can you stand 90° heat for 18 hour, no, But ,you can withstand 85 with a breeze can you not?????? I'm just asking the question????? Unless you see that plant heat stressing, yeah you need to bring the heat down.
