Hi everyone,
I have a 4x4x8 grow tent Im using a mars hydro 600 watts(260watts actual power)
And my temps range from 28c to 30c currently using a 4inch exhaust fan(vivosun 202cfm with speed controller turned down)
I have a duct opening at the bottom as a passive intake so the exhaust is also acting as an intake with the negative pressure.
With that being said Im going to upgrade and switch to 600 watts hps in a yield master sun system 6 inch hood I know I will have to upgrade my fan to a 6 inch and I have the option with using a 440 cfm metal fan with S-C or a plastic 390cfm also with a speed controller my issue is that idk which fan to go with to cool the 600watts hps (keeping noise down is important which made me lean more towards the plastic fan but worried it wont be enough to cool it and I will also be adding a filter and dont know if I should pull from inside with the exhaust to hood to filter all inside or the exhaust to hood to filter sitting outside to grab cooler air but the problem would be not exhausting the humid and co2 from the plants and just exhaust the heat from lamp and not the hot air and co2 that rises and also will I need a booster duct fan at the bottom to bring fresh air in please help im confused its my first grow!!
