Ok so today I brought a Vivosun 600w hps light to replace my 3 150w leds which were not the best lights by any means I didn’t buy them had them given to me so I have switched to the 600w which holy shit is a whole lot better but it’s getting pretty hot in my tent hitting 32 degrees Celsius and I’m a little worried just for some back story I’m in week 7 of flower with my white widow photo and week 1 or so of flower with my lemon haze photo and was just wondering if anyone had any advice I put a fan blowing directly into the hps bulb and have 2 other fans in my tent not sure what else I can do don’t have the money to go get a mini aircon or anything jarrastic so if it does get bad and as a very last resort I might have to switch back to the leds I did have a friend who was growing during flower with up to 39 degrees Celsius but it wasn’t every single day then again he didn’t do to bad nothing bad happened so any advice would be appreciated
You have a few options. The one I use is intake/exhaust fans running 24/7. I'm constantly bringing in fresh cool air in and removing hot air. The tent always has fresh air and I run unsealed reflector 600w HPS and a 300w led cob. My heat is perfect which is mainly controlled by variable fan speeds. I am running 4" intake/exhaust but will have to increase cfm and fan size in order to add another hps and get rid of the led altogether.

Your other option is get a vented sealed hood for you hps light. Most come in 6" so in order for me to hood my lamps I need to replace two fans and hoses.

Or use a 6in to 4in reducer. Then you can use the 4in fans.

With heat being a main problem I just don’t grow during the summer during that time I just focus on life
