To vent or not to vent

[Scuzzy]

Do you think a closed environment is better than a vented grow room , setting up another 4 x 4 x 2 meter room with a Pioneer P6 LED(Optic6 4k) and been told to close the room off and not use the fan or filter, now I do this I guess I would need to supply a co2 and a humidifier and may a dehumidifier is this correct or even better an ac unit, now I think using the fan and filter is a better option as only a small room but at the same time it does make it harder to contract the environment- live in a sub tropical area- dy temps around 15-26 in summer and winter 4-15 degrees - so any ideas or imput would be great

Plants need fresh air ,I have a friend who has a closed off room because he uses C02 . I would go ahead and use the fan and filter as it runs it pulls in fresh air

Vent only way to go,more better

I feel the need to vent. Much easer to control heat and humidity than a closed system. My two cents lol

If you don't vent, you will only induce mold.

Cheers for info guys, have set 2 of 4 x4 x 2 meter high tents with 2 x P6 lights from SunPlus Led, vented /carbon filters with intakes filtered through dry ice(co2) easy fix

I have always vented and run fans for air circulation but have read that if you run CO2 you need a closed system. Have always thought that would be problematic because of heat and mold but I have no experience with CO2.
