co2 question

[reallyoldg]

Working with a 12x12 room with a vaulted ceiling.
1000w hp/hps

I have decided to make it my mission to add co2 and that is where the problem starts.

I want to use a tank regulator system however I need to constantly pull odor out of the space of course co2 will go with it.
Will be using circulating fans to stir up the wind ect.

I want it hot and lit up while the 02 is going.

The exhaust will be larger than my passive intake wich will also be filtered

My exhaust fan should be able to clear the room in a minute or two.

Is the trick here to turn down the exhaust until the smell escapes and then turn it up until it stops stinking outside of the room and that is as good as it will get? During the time Im adding co2.

If I`m way off track that`s normal.
It would just be a small medical grow but I want to do it as best as I can. I understand that simply having the passive intake will draw in co2 but I want to add as much as possible without overdoing it or making it prohibitively expensive.

figured something out.
Make three different size passive filtered intakes so you have a great deal of control of flow very inexpensively. Next baking soda and vinegar method. vinegar dropping from an IV bag. Gotta be better than nothing but not as good as spending $500+-

You need to have a sealed room in order to run co2 properly ... The only thing that should be vented is your lights get the cooltube hoods... Get a carbon filter wit a fan attached nd jus let is filter the air in the room
