Install HVAC zone dampers(google it) that are spring loaded. Then install an inline fan to one end of the dampers with a timer and do an air exchange at the beginning of your light cycle. that way you can avoid a heat signiture because your lights haven't heated the room up at that point. then you run on co2 for the rest of the light cycle with your room sealed cuz the zones dampers will have closed off the airflow. and i'm assuming you have some type of way to cool the room while its sealed. yes? split system a/c maybe? also I would add a charcoal and hepa filter to this setup to avoid smell leaking anywhere and to keep pest and pollen out too.so If i definetly need it then how is a sealed grow room possible. I'm looking to have a small underground space built from pallets I have gotten for free. I figure build the box(room) from pallets then completely sealed with plastic material to keep water out. Then run a electrical cord underground for the cfl's and dehumidifier and timers for co2 . Look my problem is, I dont and wont grow if i am exhaust hot air out in the open. Even if a helicopter doesnt find it or wont find it, I will always be paranoid. I want a grow where I dont have to worry about going to jail everytime I hear a helicopter. Any advice?
Lol....without having a exhaust or intake.
science um no. common sense yes. But I have only heard of SEALED co2 systems. so from this i assumed it would be completely sealed while running co2 inside.Lol....
Are you any good in science?
Common sense if anything at all?
Sealed grows are possible, but they are usually very costly and you need to do a LOT of research in order to do them correctly. If you only want one because of helicopters, I would say it's completely unnecessary and as long as you aren't rocking like 10,000 watts or something crazy, you have nothing to worry about.I alos like to think outside the box. Most of the time I find a problem or more hassle than its worth but thinking outside the box is how great ideas are made.
you appear insultive. If you did not mean to than forgive me. but If you did mean to, you can blow me. Now i believe it is I who needs to medicateLol....
