Is it possible to run a sealed room without co2?

Is it possible to run a sealed room without co2? I wanted to use a roughly 10 ft x 10 x 8 room and was wondering if the plants would "absorb all the co2 and die"? If I wanted to avoid having to refill a co2 tank, how many of those mycelium/mushroom co2 bags would I need to put in that space?

More than it would cost to just buy the co2 tank...no it will not work

join your local brewers club

the by product of the brewing is co2 ...........and after it is done u can have beer or make it wine or even go moonshine
controlling the extact amount it release is impossible .........alls u can do is time the number of days it will be releasing and add a 2nd bucket


if u do not want anything from it do this .................white sugar 10 lbs to 5 gallons of water( heat the water up desolve the sugar) ......add in little tomatoe paste stir it in do not leave a lump at bottom a little lemon juice and then tho in some bakers yeast(water has cooled to 70-80 degrees then add ) ...........cap the bucket make sure u have a hole in it for a air lock or the jerry rigged method(this is putting the lid on lick it in taken a knife or a small drill bit and making a hole in the lid then take tubing put it in the hole with only 1/2in inside seal it with anything run the tube to the tent get a mason jar.......put a hole in the lid so the tube fits tho put it all the way down so only a 1inch is left from the bottom..........poke some holes in the lid to let the gas out and then add water into the mason jar (quart mason jar) about 2 cups u want say half inch to 1 inch of water covering ther tube end )..............the gas builds in the bucket travels down the tube and burbs out in the tent .........larger tube make big burps little tube make alot of little burps ...........1/4 works fine


when it stops burping throw it out (do not drink this or distil it will be horrible it is just cheap ) make new one u have Co2 factory

How much sugar, yeast, and water do I need to supply a 10 ft x 10 ft x 8 ft room with co2 in a completely sealed (no intake or exhaust air) if it's full of plants? And how often would I have to remix the concoction?

Run a gas line and get a CO2 generator and controller. It won't run much if properly controlled in a sealed room. Cooling and dehumidification is key in sealed rooms.

Look into a propane burner ...keeps your room warm too, but be careful

buddy u have to have intake and a exhust

the air needs to change out ........the plants will use what they can then dump out bad stuff with out u replacing it at a steady rate the plants will start to choke since they are missing parts of what they need

rem u are tring to mimic the perfert day outside all the time for the plants inside ..............u need air movement u need fresh air (during the day when lights are on plants use Co2 and dump out a form of oxyggen and bad co2 they can not use...........this needs to be moved out so it gets fresh Co2.....when the lights go out they change from using Co2 to using Oxygen .......they use oxygen dump out bad co2 and that needs to be ejected and replace)

u must have a venting or u need to invest in a Co2 scubber and a Oxygen supply units ................and even that system has venting in and out it called a oxygen farm for deep space missions

Bad CO2? Lost me there.

You DON'T have to "change out" air IF you are able to properly condition the air (add CO2, control temps and humidity)
CO2 scrubber? Seriously? Thats the plants.
Venting is the easy way to go but running CO2 when venting is a waste.

hold on i get u the info

here u go right off wiki
http://en.wikipedia.org/wiki/Photosynthesis


see there are mutli forms ..........some forms they can use other forms they can not ............so i call it bad Co2 since it is in a form the plants do not like


it would be like if u got in a deep freezer and shut the lid u used up all the stuff your body can use and now nothing but bad gases in the air and u are choking to death

I can tell you for a fact that it will work. I have a very, very sealed room that I did not run co2 in the first two years so I could test some strains and dial in the rooms. Just spending a few mins in the room will bring the co2 ppm up considerably from your exhaling. I can say that, although I was getting very good yields and due to the fact that I had environment and strains dialed in, my yield increases when I added the burner were impressive and noticeable.

no not if its totally sealed. use a large exhaust fan to pull a suction on your room and have holes towards the bottom of the room as a intake. as long as you have a negative pressure on the room it wont stink and your plants will get enough c02.

It will work, just not well. Some plants pull 80% of their carbon content from Co2 in the air.

How often and for how long should I exhaust a 10ft x 10ft x 11ft room in order to keep co2 levels good? I have a 450cfm exhaust fan

the only way to do it stable is

the co2 tank with a reg.....this will release it into the intake c02 is heavier then air it builds up and the system will vent when at exhust point and u just keep adding more in

they have controlers for this
and the valve
and then u just need a tank.......u get money back for returning the actual tanks buy them like u are using it for a soda machine smae tanke and valve size

the rest of it is on the control pannel u set it .....it releases the gas to mantain ............just hang the senor in the middle around the bud lvl not in direct light off to the side


my method is the redneck jerry rig...........this is the correct growers set up

what's the point of sealing a room, if you're not using co2, lol??? also, don't waste your money on brews, or any of the other methods like it, dry ice etc. shit don't help your plants. waste of time/money...

What difference does it make where the co2 comes from? I think the diy methods work, they just end up costing 10X as much if you want real levels in your room. If you want to just provide some, not elevated levels. I don't see why a few of those mushroom bags in a sealed tent wouldn't do the trick.

Tell you what. Get yourself one of those fairly cheap syringe co2 testers. Do a before/during and after check of the co2 levels using “any,” brew/bag/ice or whatever method to increase co2 levels. Then, come tell us how much it increased your co2 level. I think you’ll find that it is next to useless. Even if it raises your levels by 100 (which i seriously doubt,) it’s not worth the money/effort. You’ll see no increase in anything but the person’s wallet size, that you bought the mess from. tanked or a co2 generator is about it, if you wanna see any serious difference.

I have heard people measuring decent amounts out of these methods but I agree with you. If you are going to use Co2, your elevated levels need to be consistant. Tanks or burners are pretty much it IMHO.
