New grower here any help greatly appreciated.

Hi everyone, I am planning on buying an air cooled reflector in the next couple of days. The question I was wondering was, which size would be most suitable to get? 4 inch, 5 inch, 6 inch ect ect? At the moment I have a 600 watt light which when switched on bumps the temps inside the tent up to 35 degrees celsius which is to hot if I did my research correctly. Thanks

thanks for the reply vostok and the advice. Do you think a 5" cool tube and a 5" extractor fan will lower the temps enough for the plant to enjoy its enviroment?? Is there another way to maybe lower the temps? thanks again.

6 inch is what you want to run for effectiveness. 4 is to small for your needs as far as passive air flow goes. 8 is overkill unless you plan to put over 4 1K watt lights in line and connect them all in one line (cooling).

Thanks very much for the feedback. Do you know how much it may cool it down? right now I am not at the stage when I need to use the powerful light but I tested it and temps hit 35 degrees Celsius. Could i knock off 10 degrees celsius with a 6 inch air cooled reflector and 6inch extractor fan do you think?
