Do I have a problem?

With ventilation when I have a air tight (sealed) room and the light going (outside>duct>light>duct>fan>outside) then having a co2 gen and one inline HOLE (not fan)?

Is there any problem with no fresh air intake? I should be ok as long as the temp is below 82?

don't understand you. In the sealed room the venting for your hood doesn't really matter, it is considered 'outside' the room. So if you need the CO2 inside the room, what hole would you be sending it in from?

Im running a co2 Gen inside the room... which a sealed room with a exhaust fan which travels threw the light. Therefore, has no air circulation in the room. Is that ok?

I do have a 6" hole in the lower conner of the room which is the inline BUT has no fan connected yet. so if I place a osculating fan inside the room will this be ok?

I'd get a fan or something to mix up the air in the room, yeah, oscillating is typically what you'd use If you have a hole in the room that is inline it sounds like it wouldn't be sealed any longer. You want a fan inside the room... Honestly, if you have to ask these questions it might be premature to be using co2...

actually not retard... I am double checking a lot of things for a bigger project and running a lot of test in my 4x4 Mother room. You shouldnt tell people what they should or shouldnt do that might bite you in the ass in the long run. something for you to think about. GOD BLESS

Co2 isnt that much of a big deal its not like you have to be a genius to add it. all you need to do is keep a steady pace of 1500ppms in the room and have it off at night. Its not rocket science.

If you don't like my help, then listen to all the other people trying to help you.

edit: and because I'm a glutton for punishment:

It's not a question of how to add co2, that is the cake part. It's a question of getting a benefit from it. CO2 is increasing potential, but to take advantage of that you need to basically have removed every bottleneck, as well as being prepared for the requirements that will come with increased vigor. This usually means you are a very experienced grower who has a strain dialed in. Your questions don't strike me as questions coming from someone who has the experience to see the real benefit from CO2. If I am mistaken, then ok, disregard my advice. After all me suggesting that co2 might be premature is a far cry from me telling you what you should or shouldn't do. Make your own decisions, but don't bite off the heads of those giving you advice you have asked for. Your god has nothing to do with any of it

Anyways, take the advice or don't. Freaking out at people and calling them retarded is just going to get you removed from the site.

As far as your original question, I still don't really understand what this whole hole thing is, or even really what you are trying to accomplish. You have a sealed room, and you have a co2 generator, or tank, in the room. You have everything setup... I simply can't visualize what you are trying to describe. I doubt I'm the only one since there's not a lot of people jumping in with responses...

I got it down thanks just double checking things here and there and though this is the place to get respectable answers.

Heres a pic of my new room with only 1 plant that i should have SCROGed but didnt and waiting to bud it to get somthing to smoke on for the next real harvest. Im going to be going with SOG with 26 plants next harvest growing blue dream and OG kush.
