adding c02 to a sealed room need advice.

I am planning on sealing off my flower are and run ac, heater, dehumidifier. And need some input on the best way to add c02. Space is a 10x10 room. 18 plants using half the room for now. What options do I have tank or generator? Or is there something else. Plus will a tank last at least a month, if not what can I expect on a estimate. Will the tool being sealed help it to last longer? I would like to find the lowest cost to run solution and one that did not require me to refill a lot in a month. Any advice would be of help.

Thanks.

gen1 e, propane or natural gas. and then a co2 contriller. i saw a gen1 e on craigslist for 180 bucks great deal. what type of set up do u have now?

I am also in the same place as you wishing to add to my room same size as yours. I want to add a question...what about odors? Without a ventilation system how is the air scrubbed? Without there being a negative preasure on the room would not the smells eventually find their way out of the room? Do you c02 users just run a carbon scrubber in the room with both intake and exhaust in the sealed room?

Thanks pooters for starting the thread

thats the pefect condition scrub the air. the prob is a great a/c is used to accomplish the perfet ambient temps in your room and that gets pricey.

Rite now I am not supplementing c02 just exhausting the air. As for the temps during the winter months and due to location of the room I have to heat when lights out and the exhaust fan hardly comes on when controller is set at 80. As for summer it is naturally cooler in that room and I have central air that will also be running with the 9,000 ac unit. If the temps still go to high I might air cool my hoods or look into water cooling. Or go back to exhausting. For those propane or natural gas c02 generators do the tanks last a decent amount of time.

Grasshopper, I planned on running my online fan with filter vertically in the corner scrubbing the are in the room. U can also do a ionizer. Orders would come out my room as is when the fans stopped running for a while.

im on my first bottle of propane right now. im 11 days into flower. and i burn 8 burners. so u might get more propane use.

What size is ur grow area. I am curious to know if I will need that many burner aswell. Also do u get any added heat from it or is it water cooled. I was asking also because I stumbled across a c02 tank and regulator for only 50. But if it won't do the job I want its not worth getting. Mongo frog I would like to ask a favor of u, when ur tank runs out let me know how long it lasted by either a post here or a pm, thY would really help. I am taking a few days off to demo my room after my current grow finishes in 3 weeks. Then I am starting all over with some new seeds. So I have the time to wait and collect info so I get the rite thing for my set up.

the room 18x 19, i get a little heat but on the gen1 and gen2 e series theres no standing piolit so its not that hot cuz the piolit lights only when co2 is needed. a huge plus. ill let u know how long my bottle lasts for sure.
