thats false. every one knows a completly seald room is ideal, but if u r enriching and have monitors to show levels are correct you will benifet greatly.

for any measurable results the statement is very accurate...if it is not sealed and no steady continuous supply much greater than anything other than a tank or burner can supply is no supplementation as the levels will not remain elevated enough or for a long enough period of time to make measurable gains....but you can believe it does if that makes you happy

I'm a fat guy. 5'9" 258 lbs. I do about 50 jumping jacks in my grow room and thats all the CO2 they need. Cause whem I'm done...I breath really heavely on my plants. FAT BOY POWER BITCH.

New method a friend told me about, which I've been using for several weeks with decent results:

What is needed: 1 gallon jug, yeast, sugar, thumbtack, rubber band, and a condom.

In the following order add the following:
- 1 Gallon Milk Jug (or similar)
- 2 Tablespoon of yeast
- 2 cups (or more) sugar
- Add above using a funnel or make 1 out of a piece of paper, then add "Warm" water filling to about 1 inch from the top
- Poke 4 holes in the condom, 1 in each corner
- Open & Unroll 1/2 of the condom
- Place condom over milk jug, and use the rubber band to secure it.

Shack the bottle & the condom will fill with co2. I use 4 jugs for a 8x8 space. Shack jugs whenever you see the condom not erect :) After about 3-4 weeks you will need to add more sugar, but not yeast as the yeast will reactive with the newly added sugar.

Not sure how much CO2 this creates, but some is better than none for your ladies. Your jugs should last a few months before you have to create new ones.

Peace out

Plants require carbon dioxide to conduct photosynthesis. Greenhouses may (if of large size, must) enrich their atmospheres with additional CO2 to sustain and increase plant growth.[18][19][20] A photosynthesis-related drop (by a factor less than two) in carbon dioxide concentration in a greenhouse compartment would kill green plants, or, at least, completely stop their growth. At very high concentrations (a factor of 100 or more higher than its atmospheric concentration), carbon dioxide can be toxic to animal life, so raising the concentration to 10,000 ppm (1%) or higher for several hours will eliminate pests such as whiteflies and spider mites in a greenhouse.[21] Carbon dioxide is used in greenhouses as the main carbon source for Spirulina algae.
In medicine, up to 5% carbon dioxide (130 times the atmospheric concentration) is added to oxygen for stimulation of breathing after apnea and to stabilize the O2/CO2 balance in blood.
It has been proposed that carbon dioxide from power generation be bubbled into ponds to grow algae that could then be converted into biodiesel fuel

My rooms are 10 x 15 x 8 and I go through a BBQ tank every 7 to 10 days, and I run at 1800ppm so the whole room is at 1500ppm when it shuts off.

It takes less than 2 minuets for a plant to use all the co2 around it in a stagnant room, always have a small fan blowing gently.

Do you have a ppm reader? leaks? I believe that it takes more than 2 mins for the plant to absorb all the co2 in a sealed room. I had 18 5 ft plants that still took 30 mins to absorb the co2(1500ppm) in the same identical room size as his. Depending on the number and size of your plants, it can take to 1/2 to 1 1/2 hour before all the co2 is absorb. The ppm should decline before the night cycle turns on because the co2 will be useless once the lights are off, extending the life of the tank. My regulator turns off a hour before night cycle turns on.

Thank you for the useful information. Source, wiki?

like smelling the chared remains of humans flesh lol crazy thought i know but maybe it can? maybe its like i can smell you killing my people! i hear the screams! plants do scream by the way.
they are a lot smarter than we may give them credit for.
I wonder what they think when I light a fat one in there almost daily...

Sorry, still learning here.

Watch the secret lives of plants. A movie from like 1979. I saw it on Netflix. Some pretty interesting stuff! Plants that identify someone out of several people that mutilated the plant next to them in the room via polygraph. And plant going ape shit on the polygraph when brine shrimp are dumped into boiling water in another room! Pretty crazy... I was thinking the same thing last night watching the girls bask in yellow waves of HPS and burning a fatty! Ahhhhhh! I'm sure they know how much we love them by the RED enjoyment in our eyes.

Looking for info on a closed loop systems. What's required?? Air Conditioner, Heater, Dehumidifier, Humidifier, CO2, etc.

From what I've heard this is the best way to control your environment, and keep pest at bay. Would love to learn more and see some pics of these systems in action.

Peace out

my system is closed. Its the only way I can keep the ladies cool while keeping the intensity right, plus that way they can use extra intensity because of the co2 concentration, I use about 65 watts/ft^2.

In the summer there's no way to keep a room cool without ac. If you vent a bunch of air from the outside at 95f, your rooms going to be 100+ at any decent intensity. And unless you're providing some source of co2, whether fresh air or a concentrated supply, your plants are going to suffocate. With one small light a room is small enough that you can push say, your air conditioned air from your house through your room and out the window to provide fresh air without wasting too much of your cooled air. But with bigger grow rooms, a separate ac is necessary and you certainly don't want to be wasting all that cold air. So, you need a dual hose ac which eliminates negative pressure by using both an intake and exhaust to the exterior to cool the compressor. That will keep all your cold air inside; now you need to add co2. Since you need to conserve the cold air produced by the ac, the only option is to add a concentrated co2 source. I prefer compressed tanks because of the ease of operation and the fact that they don't produce unwanted heat like generators.

The air conditioner should allow you to maintain low humidity levels and temperatures, and the lights should provide sufficient heat. While the humidity level may be lower than ideal, especially for vegetative growth, it can be accounted for by lowering the concentration of nutrient solution supplied, since your plants will be transpiring at an accelerated rate. Anyhow, the serious problems arise from high humidity levels which cause various forms of mold and fungi. Using a small humidifier or misting is efficient in raising humidity in small sealed rooms if desired.

If running normal co2 concentrations (300-400 ppm) the ideal temperature is around 72-76f for most strains, however, if using elevated levels, 1200-1500 ppm, the ideal temperature range is a few degrees higher. When I used to run normal co2 levels I preferred 72, now that I use high levels I am still nervous about approaching 80f, but I try to keep the temp near 78.

Saw a fly in my room once and put the co2 hose up to it with the regulator on. Its movement was slowed instantly and it died momentarily.

hope this helps!

for the rest of us who live in the 90% of the inhabited world that experiences uncomfortably hot temps in the summer, hopefully my post is helpful.

.....I'm growing 4 plants in a 8ftx2ft closet and i saw a thread on another forum where the dude calculated the amount of co2 the plants would get from me spending time in the room. dude said that to create the necessary ppms you'd have to spend an hour in the room with your plants but then again the plants use up the co2 quickly so it would be best to go in there every half hour. want to know if this is actually effective for anyone since the math seems about right
