Hey guys, I'm growing in a 1 metre by 1 metre 2metre tall tent. Got 1 315w cmh hung vertically with some trellised girls 4 weeks into flowering. Hot weather has caused some cooling issues already, hitting temps of around 35c. Would adding a 600w HPS be worth it? Could I switch it on for a short period to mitigate heat issues? If so, when should I get it to come on? I was thinking the theoretical "midday". Thanks.
