Mold!!!!!!!!!!! you need ventilation. If you dont your plants wont function properly. They wont transpire aswell. You dont need an intake but you really need an outtake
I agree 100%! Massive ingorance in this thread.Yes u can do it without intake or outake ... In canada we do it ...and call it prefect room setup ... Put ac in room with co2 ... Not sure why people sayin it will have mold or wont grow ... Thats straight bullshit
to anyone who say having exhaust is a must read this article i found http://www.cannabisculture.com/articles/3368.html
Closed Growing Environment (CGE)
No, a closed grow is just that, closed at all times. You deal with humidity with AC and dehumidifiers, with drain lines routed out of the room. If you're venting at night, it's not a sealed environment. And if you're running your system as it sounds, not venting during the day but also not controlling the humidity during the day, you're asking for mold.Guys,
In a closed grow the room is sealed when the lights are on. A portable AC unit is used to control the temperature and a Co2 generator is used to keep the ppm at the optimal level. Plants exhale gases at night and do not require Co2 so venting the moist exhaust air is a must. I use a 4" inline fan through a Carbon filter for my exhaust so I don't have my neighbours smelling my products. Co2 can increase yeilds up to 30%.
Hey Wolv97, do you run a sealed room? Im in the process of designing one and could use some pointersI can't believe how much bad advice is in this thread. A totally sealed room is the absolute best way to grow. Period. You still have to control temp, humidity, co2 etc, so it requires a bit more equipment up front, but by all means if you have the ability to do this, DO IT NOW.
Sadly, no I don't.Hey Wolv97, do you run a sealed room? Im in the process of designing one and could use some pointers
