One thing you should know is thatā¦CO2 is lighter than air and needs to go from bottom to top otherwise all your CO2 is getting sucked out through your filter.
Second your taking a chance of cross pollination from your tropics tent into your grow room.
Third at those temps your yeast is dying faster than it produces and itās not a constant amount plus adding it 24 hours a day in a closed space will do more harm than good , and again you have no way to control the actual amount of CO2 being provided
Co2 is heavier than air thatās why co2 alarms are floor height not ceiling height.

Then why does the fire department tell you to crawl in the floor? You would 9ass out and die from CO2 exposer. Radon is tested at floor level

Thatās literally the opposite of everything Iāve been told my whole life. Guess I need to relearn some things
Iāve been in construction my whole life a licensed general contractor in 4 different states and was the regional superintendent for Victoriaās Secret setting up their new store locations and Iām going by building codes both residential and commercial that ive had to use my entire life , plus the extra curricular activities Iāve done I have a lot of cross knowledge that Iām able to use.
Now like I said , I never ever said they were wrong just that it was not the only way to do something and his way might not work for everybody and thereās a lot more to it. Some people might not want to try if they knew the downside of it but others might be intrigued. But thereās no perfect DIY setup for everybody , thereās no perfect set up , I was just giving additional info from my own personal experience and knowledge to help.

I know nothing about DIY or store bought I donāt have a desire for the limited returns on a small scale. I was just confused by the stuff being said cause it goes against what Iāve been taught in school and as a contractor. As for how it works in a grow I wouldnāt ever try to tell someone how to set it up cause itās foreign to me. I probably should have just sat this one out.
Your completely fine donāt worry about it. I was just saying before that it wasnāt the only way to do it and thereās a lot more to it and not as simple as it sounds and wanted everyone to get as much info as possible before trying it. I know you said youāve never done it which is coolā¦but Iāve had those bottles explode on me before and the mess it creates 0lus the smell along with the fact if it happened inside a tent it would literally kill everything in it.
Iām not jumping on anybody and dont mean to offend anybody , Iām just trying to help people make a more informed decision about whatās involved in it.
I said my peace earlier but past that now , Iām just passing on info from my own experience is all. If you do have questions please feel free to ask were all here to help each other.,

Actually no c02 is Not heavier than Air , hope this helps
CO2 (Carbon Dioxide) is heavier than air. One molecule of carbon dioxide is composed of two oxygen atoms and one carbon atom. Combining the atomic mass of all these atoms, the molecular mass of CO2 is 44 while the average molecular mass of air is around 29. Further, the combined density of air is 1.22 Kg/m3 while that of carbon dioxide is 1.61 Kg/m3. Hence, carbon dioxide is quite heavy in comparison to air.
Itās all goodā¦this is probably a Lost thread and wonāt get much response.
I originally started this to try and get an idea of how much to expect on harvest but never got a straight answer and then the Co2 argument started and got the entire post off track.
I know what the building codes areā¦
I know what the health department requirements are ā¦
I know what the US fire Marshal saysā¦
Iāve been a licensed general contractor in 4 different states plus superintendent of Victoria Secret doing their store setup and over hauls.
I had to follow these guidelines or get major fines and job shutdown until itās fixed.
Iāve had to deal with these codes , regulations and laws for 40 years now both residential and commercial.
You are more at risk of Co2 exposure at chest level than you do in the floor
Read the thread a while back . . . some of us add CO2 during the grow. Some of the info you provided refers to CO (carbon monoxide) not CO2 (carbon dioxide) . . . CO is lighter than air and rises, CO2 is heavier and falls.

Actually it donāt matter because I donāt run enough plants or use mega lighting for it to be beneficial to my grow.
But like I said this is not what the original question was in the first place and off the topic.
Whats going on bud? Hows life treating ya? Just wanted to jump in and say hello lol but also if you were still curious about the m2 deal i believe @Crackadoo had a good point on the 3rd message in thread. I also believe they go by multiple plants in a square meter which i think is 3 square ft but fuck if i really know i just googled it 
but not knowing how many plants they put in that area is tough unless able to ask breeder i would think. But giving the general rule of plant having at least 1 square foot of space im assuming 9 plants in an unknown potsize maybe 5g if i was to guess or fewer plants in bigger pots unless dealing with autos then id think 9 in 5 method again

Thank you , that makes sense to me.
But Iāve got to the point to where Iām getting at least a 1/4 pound off each auto and looks to be only getting better. Got another 3-7 days drying my Do-si-do to see how much she has but have a feeling itās gonna be closer to a 1/2 pound from her.

And the laws I HAVE TO FOLLOW for work contradicts what is being said. No house would have a basement and the fire department would NOT tell you to crawl in the ground because you would pass out before you left the room. YOU DO NOT MONITOR CO2 AT FLOOR LEVEL!!! YOU MONITOR IT AT CHEST LEVEL!!! I have been dealing with this in a far more technical and legal aspect than pretty much anybody else on this site. You can fight and argue about it all you wantā¦but I go by federal building codes and laws in order to keep my licenses and nation wide master certificateās.
Plus I bred Angel Fish and Live aquatic plants using Co2.
I know what Iām talking about , in fact you donāt even run it 24 hours a day like most people because itās useless at night and unless your running more than 10 plants under high intensity light YOU DONāT NEED IT!!!
Plus your cats and dogs would die from lack of oxygen.
Youāre confused and talking about the wrong gas . . . capitalizing your words donāt change that fact. You donāt monitor CO2 at any level in a single family residence unless you have a grow room, you monitor for radon and CO. Ask your high school chemistry teacher. Hell do a internet search for CO2 alarm and all youāll find are CO alarms. CO2 is the gas in question but you keep talking about carbon monoxide and how qualified you are to answer construction related questions.
You are correct that we donāt need CO2, we donāt need hydro either, just need a bucket of dirt . . . but does not needing it mean that it canāt improve yield?
If you believe Iām wrong then thatās fine . . . maybe I am mistaken and CO2 behaves like carbon monoxide as you state. Either way . . . no point in arguing.

Hell I have 40 years experience dealing with this and know far more than you do !!! Yes you do not test in residential homes because itās w a waste of time and moneyā¦but if you read I also hold commercial licenses which include hospitals and their air quality systems. When you have the qualifications to shut down a hospital because their system is out of wack then tell me. Iāve dealt with Co2 on a professional levelā¦not hobby.
Plus YOUR STILL OFF TOPIC TO THE POST!!!
I apologize for steering away from your main Question Topicā¦ I can say this about yield / equations
depending on the Power of your light, PPDF DLI levels and day hrs, you can find your Answer from the Manufacturer. Example LED AGLEX 650W LIGHT
2.5g Per Watt Average = 1,650 gram potential in a Full 5x5 tent.
another option is find the genetic strain Information online of your plant, they usually have a formula there already. example: American Kush = INDOOR YIELD10 to 12 ounces per square meter, 12 oz every 3 square feet of colas per plant, or OUTDOOR YIELD12 ounces or more per plant.
i hope this helps
