Need Co2 advice

[denverbear]

Just picked up a tank of Co2 and a regulater and need to know when and how it will work best...setting etc. want to try to do it right the first time for sure..
lites run about 18 hours a day in this room.
We strung some 3/16 hose into the T5 room and drilled holes about 2 inches apart under the T5..when would be the best time to run Co2 in this room ?

also do we need to turn the fans and can fan off when we turn the Co2 on..?

Main grow room under the 1000 sodium lite we where thinking of doing the same thing or should we run a individual hose to each plant ? also when would be the best time to run in this room as the lites are 12 hours on and 12 hours off.

also about where would be the correct setting on the Co2 flow meter..we where thinking about 1000 to 1200 ppm but someone told me we could run this higher and up to about 1500 or so....
thanks for any help you could give us..we just do not want to mess up our first crop. :pimp:

co2 enrichment is normally done in a closed room. It's kind of pointless to pump co2 into a room that uses ventilation to control air temps. Maybe if you had a co2 generator, but with a tank you'll be filling it up twice a day just trying to maintain 600ppm's lol. My numbers might be off but its really not cost effective imo. Do it right and seal the room, air cool the hoods, put a window unit in or split unit. I modified a floor unit into a split unit with ease...

Temps are suppose to be higher with co2 but I only run 80. Some people run 85+. My co2 level is set at 1400ppms during the day. No co2 at night. Hope this helps. Keep doing research. :jointsmile:

[copobo]

CO2 is not called for in veg. It must be a closed room as TurboALLWD said or your just throwing money away.

CO2 is really for flowering, should only be run when the lights are on. A common setup is to use a controller, set ppm to 1500, and top temp to be 90. Then, the controller will come on and dump the air in the room, and when finished, bring ppm back to 1500. Plants like it hotter when there is CO2, and can tolerate and thrive in higher temps.

CO2 should be NOT be run the last 2-3 weeks as your buds will not swell.

Definitely want to run CO2 in a closed room. Remember CO2 is heavier than air, so have a fan blowing it from the floor. If you have problems controlling heat, you can have a small exhaust at the top of the room as long as it does not have a high flow rate. I personally use 3 small pc fans exhausting heat using what I like to call a "top to bottom" method. Meaning my fans are built into my framing. Heat from inside the grow room takes a trip through a hole in the top of the ceiling and exits out the bottom of the wall on the outside of the room. I can still maintain perfect CO2 measurements using this method. I grow using strictly CFLS and I don't really have a problem with heat. I noticed you use a 1000 watt HPS? Good luck cooling that sucker! lol.


I maintain temps between 85-95. I control my CO2 with a bubblemeter AND a CO2 reader ($200!), just to be sure I don't burn them. I run about 1500ppm during veg(after they get a few leaves), and 700-1500 during flowering. 1500 during the first 6 weeks, 700 during the last few. I only reduce during flowering, bc supposedly there is evidence that proves co2 during flowering reduces potentcy. I have a fan in the center of the room blowing towards the ceiling. The CO2 hose is tied to the ceiling, above the fan. My room was also sealed with silicone and plastic sheeting when I framed it (air tight!). No CO2 at night, because plants give off CO2 at night, and use it during the day. So remember to exhaust at night especially. Did I miss anything??

Just have to find what works for you! Like turbo said, RESEARCH!

[denverbear]

We think the room is sealed pretty good...we used the plastic reflective mylar and gorrilla tape to seal from top to bottom...when the 6 in can fan is on pulling air thru the charcoal filter thru the lite into the can fan blowing out the window the walls are pulled inward pretty good....what we are thinking is that if we run the co2 for the first 15 minutes or so when the lites come on we would use timers to shut off the fans and the co2 on and where wondering if doing this every for hours thru the lite cycle would help meet our goals or do we need to use more often ect..the room stays around 75 when the lites are on and humidity varies from 34 up to about 48 pct during the day......we do not use any air conditionar or heat other then the fixed air blowing thru room...the big lite comes on about 5pm or so and runs until 5am....trying to run the big lite in middle of nite when rates are cheaper(is this a good idea ?)
thanks again as I am really starting to get the hang of this but know I have so much to learn and enjoy talking to you all about what helps us all..

I hope I have given enough background on this project...

retired and happy. :D

Timers with the fan on and co2 off and visaversa... sounds like a good idea to me. I don't see why that wouldn't be beneficial. I would increase the co2 to fan time ratio though. (Maybe a half hour, instead of 15 min.) Running lights are up to you, but remember light leaks are easily seen at night. Depending on where you're located the cool winter night temps will help keep the room cooler when the fan is off and the co2 is running. Other than that, you're on the right track.

[copobo]

it is def. some bucks to set it up with a cap controller and sniffer.

I just kept adding parts to my room one at a time.

AND - Just keep doing it man! There's much to trial and error and observation. Keep reading and asking and trying. I'm psyched to hear you decided to grow.

hth
How do you not use co2 the last 2-3 weeks if you have plants at different maturities in flower at the same time, i.e., a perpetual harvest set-up?

[copobo]

it's hard. for awhile I ran 1 week on, one week off. I am syncing up now, for just this reason. Everyone in flower is w/in 3 weeks of each other now, and next cycle I am syncing.

I am doing this for a few reasons, not the least of which is having to mix up sometimes 4 freaken sets of nutes! FUCK. that'll make you wanna jump off the edge!

EDIT: so yea, till now, I was perpetual. I did this for variety, but at this point, that doesn't matter because of previous work.

If you don't/can't have sealed room, then supplemental co2 is pointless. Normal air quality already has approximately 300-500 ppm. Depending if you live in a city or not. The point of supplemental co2 is to get the ppm up there around 1500. You might as well sit your tanks outside your front door and let em open. It's not necessary to supplement co2, just a kick in the plants but to get growing.

[copobo]

you nailed it. if you can't close the room and do CO2, move air like crazy instead. cheap and effective...

[denverbear]

thanks for all the help everyone...the only problem we are having now is with some of the plants are dropping leaves (2 big ones ) and leaves are kinda yellowish and drying out...we had gone by Delta 9 and he suggested using kelp and seeing if that helps..hopefully that is the answer..

thanks bruddahs for all the input about the unsealed room probably not gonna work..............wish i had thought of that before i $ that.....but hey.....the girls look fine most all the time but yields were goin down....thought i give the ol stoner try.....not givin up on it just yet tho......with a little more vaping and some farm enginuity i,m gonna get some co2 on those little girls(BK PK OG D JB BG 47/48 GA BLD BD CH MM GF)

It's not called for in flower either. lmao It will make your plants veg like no other.


Plants like it hotter when there is CO2, and can tolerate and thrive in higher temps.

Some strains dont like it so hot. Not all of mine were happy at 85-88 so i'm at 82 now.

Really? I run perpetual harvests most of the time so I wouldn't know. [attachment=o262556]:jointsmile:

Grobro- $100 used 9,000 btu floor unit modify it for a 6'' intake duct. That's the ticket, especially if you already have a co2 setup.

[TurboALLWD]

this post might be useful to you growers stuck on wasting your co2.


A quote from my journal...
I need to make changes in the co2 schedule again. Staying to hot in the grow room with the extra 1000 watts, so the co2 calculator says, co2 for 8 minutes @ 10cfh at 8:30am to get the room to 1500ppm of co2. Then 2 more minutes at 9:20am to get the levels in the room between 1500ppm and 1800ppm of co2 (guessing at how much co2 is lost/used in that 50 minutes). The exhaust/intake fans will kick on at 10:00am,and exhaust the room, and turn off at 10:29am to remove the unknown amount of co2 in the room. The co2 for 8 minutes again at 10:30am to 10:38, and repeat the above schedule every 2 hours. Temps are staying between 78-86 degrees.
Using this technique I keep the room warm enough for the co2 to be effective, and the room is flooded with 1500ppm of co2 75%-80% of the time.

Not only is it not cost effective imo, the temperature fluctuation from this technique is most likely counter productive. With the temp and co2 fluctuating that much I have a hard time believing they would gain anything over a nice ventilated grow. My plants in my ventilated flower room are doing just as good as the co2 flower room. lol

[MtnLionCO]

just get a co2 controller/indicator, it will help you dial in your ambient co2 level. if you grow in your house then you will find the correct conditions to keep it consistent without supplementation, i .e. keeping your window open 1 inch rather than 2 inches etc. once you do this you can keep the co2 constant at about 1200 parts per million. wonderful device.

[MtnLionCO]

you have to understand what is there before you can know how to act on it. once you get the co2 indicator you realize you dont need co2 supplementation.

Are you saying this with the understanding that you ARE supplementing co2 and using your window to control the ppm?

Or are you saying you just open your window, and you can control co2 within your home without using supplemental co2?

[MtnLionCO]

without supplementation.

[MtnLionCO]

the window open 1 inch would be in a room adjacent to the grow room, not the actual grow room itself. the larger your house is the easier it is to control the ambient conditions.

[MtnLionCO]

animals emit co2 and plants will use up all the co2 available and in turn emit oxygen which animals consume as much as is present. its a wonderful symbiotic relationship.

now tell that to Al Gore.

[copobo]

I wonder what the source is?

maybe you lived over an old coal mine or something? malfunctioning water heater?

earth ambient cO2 is ~388 ppm

[copobo]

Really? I run perpetual harvests most of the time so I wouldn't know. [attachment=o262556]:jointsmile:


not that kind of swell. Calyx swell. I've also heard it decreases potency. I get more crystals when CO2 is not run the last two weeks. If I get some time, I'll pull out some bubba I did an experiment with, one w/co2 off the last 2 weeks, one with it on, and take some pics. The difference in resin production is noticeable.

[sum1cull911]

I wonder what the source is too? I doubt you could get co2 levels that high (not that it's super high) without supplementing in your home... unless you have a smaller home, very well insulated/air tight home, or you have lots of people/animals within your home. Like COPOBO said, a malfunctioning water heater or something to that extent sounds more likely. Not to mention, atmospheric CO2 is only 388ppm. I can sit in my grow room(which is only about 20 cubic feet) for 2hrs and the co2 ppm will go up to 2000ppm. Which is why I say it must be a small area. I don't know what your grow conditions are or where you're located, but it must be hard to control the other necessary "grow room" conditions with an adjacent window hanging open? Especially with changing seasons?


By the way, I believe it would be much easier to control ambient conditions via smaller areas... not larger ones. Why do many scientist/researchers do their test via small scale, rather than large? Larger areas take a longer time to acclimate than smaller ones, therefore smaller areas are easier to work with.

You're right though, it is wonderful. Although, I would call it the beautiful cycle of life. Symbiosis is defined as a relationship between 2 unlike ORGANISMS. Last time I checked, CO2 was an ELEMENT.

BTW, I know I sound like an ass... but I'm truly not trying to be one. I just don't know how else to word it. Sorry.

[copobo]

i can see symbiotic between plant > person w/the person providing co2 and the plant providing thc ;)

[grobro]

what do you think the max co2 ambient level 'could be 'just with a door/window open /closed ......without a co2 add.....non sealed room....
plenty of flow.....w/exhaust fan suckin it thru....?
w/circ fan also.......
basement w/grow room within it....good clean fresh mountain air......guess i really need some type of metering $........to really know eggs ackley

[copobo]

ambient here is 370-410 IIRC when I was first setting up. (5100ft) I think mine is influenced by something local, making it a bit higher. I think next time I turn it off for 2 weeks I'll bring the sniffer to my desk and watch it for a few days.

I felt like I was pissing in the wind w/out a sniffer/controller setup..

I have mine to kick in at 1200ppm and turn off at 1550 ppm. humidity of 80% dumps room air. Temp of 92 dumps room air (considering turning this up to 95). A photo sensor won't let it add co2 at night.

For me, my vegging plants are always way ahead of the flowering plants. I want to start 12/12 with them smaller. (they are going in at 5ft now) I already only use t8's and have ppm's dialed back to 700... so CO2 just isn't needed in veg for me. ymmv.

[grobro]

thanks for the input..........good meter $ ?....brand name?......
low tech baking soda method?.......co2 bags?.....

[copobo]

you don't want to mess with that crap. I think just setting a tank on a timer would be more cost effective than that. If you are thinking about doing co2, you plan to do it from here on out, right? so why fuck around and do it wrong first? You'd be better of waiting and saving your $$ and doing it right. In the mean time, keep plenty of fresh air moving through.

google this
C.A.P Air-3 and C.A.P. PPM-3=
one is the sniffer (monitor) and one the controller.

I've got a co2 meter, and it wasn't cheap. Very accurate. I've never seen it go past 700 in a normal sized room, with 4 people in it.

@ sum1cull911 you must be living a different planet than i am.

[MtnLionCO]

the relationship is between the human being and the plant.

people give off co2 when they breathe.

its not a broken water heater or a mine shaft.

larger space means less fluctuations hence easier to control.

small animals dont affect it much at all.

i know its calibrated correctly because it drops to 400ppm if i open all windows, or take the meter outdoors to test it.

or you could run the co2 in the secondary room where the cold air is and transfer air via fans/ducting 24/7 with no cycling.

thats not true, if the rest of your house is closed up the room doesnt have to be "sealed".

who grows in a sealed room anyway, you would need to run an air conditioner if your room was sealed (which creates more heat). and how would you control the humidity? mine stays constant at 40%, it doesnt go up to 80% and then trigger an exhaust fan. and my co2 stays constant at 1200 (from me breathing) it doesnt fluctuate around.

I misread your post about co2 and symbiotic relationships. Completely sorry.

But smaller areas ARE easier to control. Supplemental CO2 is pointless if you are not running a sealed room with controlled ventilation.

I grow in a sealed room. I have no problems with controlling my temp/humidity AT ALL. Everyone has to try what works best for them. The fact that you're calling me a liar in half my posts, only proves your ignorance/inexperience on the subject.

Do you stay in your grow room all day long? If you don't, then how the heck could it stay at 1200 ppm constant? "Who grows in a sealed room anyway?" Well, who stays in their grow room all day, anyway?

I won't mention how I think you got those big ol lungs of yours. But I'm guessing it's not from smoking.

Your acronyms are confusing me. Haha.. IMO=In my opinion? CGE=Controlled Greenhouse Environment?

You're right. To a point it is pointless. But for people who use HPS lights and such, they need the ventilation. Some don't/can't use AC's.

I say a half hour of supp. CO2 @ 1500ppm every half hour, is better than no supp. CO2. As long as during your CO2 ON time, your room is sealed. Because you're already losing CO2 when the fans kick on, why would you wanna lose co2 when they're off?

I will nicely ask that if you are in this thread to stir things up then please start your own thread as all I wanted was some help from other posters who could possible give some great insite on possible mistakes we are making so we can understand what it takes to have a better product.....enough said...thanks again everyone...

we have figured out today that the co2 gauges may have been put back together by previous owner and the threads crossed and the o ring was trashed out.....we are trying to figure out if we can fix this by getting a new ring but are having trouble finding the right one...does anyone know who might carry such items ??

I bet the grow shop has them, or a beverage distributor. same ones as for co2 beer systems. they are very cheap, get 5 and tie the rest to your regulator. If your metal threads are okay, nothing to worry about.

I mean the temperature causes the room air to get dumped before the humidity gets too high. At night I have a dehumidifier that will kick in above 60, but it never turns on.

I've never (knock on wood) had mold. PM, yes, but it's been a long time now. pretty dialed, but always willing to learn :)

seriously dude, just a heads up, you won't have many friends if you randomly drop disapproval ratings on people trying to help you. don't be an ass!

I think I've used it twice, ever.

IMO, it's for marking people who are intentionally being douchebags.

seriously bro, with all due respect to denverbear, but do you actually think i wouldnt notice if i was living over an old coal mine, come on dude.

and making my neg rep public i would consider gay, even though i realize it was the other guy who said i was gay (which i am not).

thanks for the advice lol, i checked my water heater and its not malfunctioning.

obviously this is pointless.

[TurboALLWD]

Yep, What Copobo said. And use teflon tape on the threads especially if there chewed up.

Right on Copobo. Know were any cheap charcoal filters are? for 6'' fans. The Chemdogs upstairs absolutely reak.

[MtnLionCO]

bottom line is anybody can buy a co2 monitor and test it for themselves.

you could run co2 in your basement with a grow room upstairs as long as your house is closed up. doesnt have to be "sealed".

i know because i have tried many different things for myself so i know what i am talking about, that why i am making a post here in the first place. not following some manual for the first time.

Do you mean with an HVAC or air system circulating the CO2 through the house? Assuming you have an HVAC / Air system in your basement?

[MtnLionCO]

2 high speed fans is all you would need and some ducting, 10 inch can fans.

[copobo]

that would be alot of co2 for a whole house.

here's a cool page to check out

Why wouldn't you run the CO2 in the grow room? Why would you run it all the way from the basement to the upstairs? If your grow room wasn't sealed, then you would be filling the house up with CO2. That would be a waste, right? That seems like a lot of extra work and money.

I think dangerous levels of CO2 for humans starts around 10000ppm. Even still, that doesn't seem like it would be good for your health.

[copobo]

it would make sense if you were doing a whole-house grow

im here offering my personal experience, and you offer me an article.

its not a debate or popularity contest, like i said , my best advice to a newbie is to get a monitor first.

i go on to detail how my c02 level was high enough without supplementation from me breathing, and you say its only possible on the moon or over a coal mine.

i feel i have to defend myself here because you could have simply given your experience, but you are trying to make it into right and wrong. i will let you defer to your mainline articles, im actually here to learn not try to sound like i know everything, which i dont, the more i learn the more i dont know.

MERRY CHRISTMAS

Your experience does not always make you an expert. My wife has 15 years of experience making me dinner. She's no top chef.

Your right, this is no popularity contest. I think I can speak for a few of us when I say we are just confused by your method. Everyone is only here to help. Our meds are important to all of us.

When I said I am doubtful of your high levels of CO2 concentration without you having supp. CO2, it's because of MY EXPERIENCE. I have a meter like you suggest for others to get, and I have never seen ambient levels of CO2 rise that high without supplementing. Unless of course I am breathing on the thing or in a small room. We were only trying to find a logical explanation.

You claimed my experience was "ridiculous". I flat out told you I was not trying to be an ass, yet you still reacted negatively.

I am still curious as to how you have your setup, if you could help me understand? I mean no harm.

[copobo]

I wonder why you are taking this personally? seriously man. this is just a conversation. I learn and try new stuff I read on here all the time, far from figured out. I agree on the monitor 100%. remember, we're just screen names on here and nobody can see your experience.

[ThaiBuddhaMan]

MtLion's responses seem a little out of character, maybe someone is having a really sh!tty day.

MtLion - relax, it's just a forum. People are just sharing ideas. Yes some toes got stepped on but mostly we have similar goals at heart.

[ThaiBuddhaMan]

Ok just posting this as I can hit 420 for my post count. Might have to quit the site now and leave it there! HAhaha!

[MtnLionCO]

if you have a constant air exchange then it makes no difference whether your co2 is inside the grow room or in the secondary room where the air is being exchanged.

you cant visualize a small basement with co2 generator and a grow room directly above with holes cut in the floor?

what was described originally was a basement with a smaller grow space made within the basement, same idea. the secondary area should be 4 times as large as the grow space.

i am not in a bad mood at all, i simply responded to each post which was a mistake.

So you're saying the air exhange is constant in the secondary room, and your co2 is in the secondary room... ? You release Co2 into an area 4x's the size of your grow room, instead of just in your grow room?

[denverbear]

my partner got the o ring and re-installed it but the regulater still won't work...it seems like the co2 just does not go thru the regulater to the up and down dial so we can set the limits..when we plug it in it clicks but no co2 is comming thru... and yes we do have the tank turned on...and the valves open....lol

[copobo]

if you take the regulator off the tank, and open the valve on the top of the tank - very, very slowly, aimed away (!) from you, does any co2 come out? does it have a pressure gauge?

[TurboALLWD]

yea you should verify the gauge shows tank pressure. The solenoid on the regulator is normally a cheap piece of shit. The spring in mine wouldn't have enough pressure to keep it closed. Sounds like your solenoid is stuck closed, or you're tank is empty. lol

[denverbear]

took it to a hydo store and found out it was the solinoid...they are fixing it as I type this...cheap piece of crap for sure.

[TurboALLWD]

Once you get it back keep an eye on it if your using a timer. Mine keeps sticking open and sending my ppm's up to 1600-1800. I've burned plants because of this problem. Going to get a new solenoid asap.
