dont you need a timer board, and for 6 lights at a time you will need a 2 fan 3 coil chiller or burn all ur buds to shit a 12000 btu air con will suck out ur co2 plus the exhaust from it will reek since u only got one filter and ur rom will still b hot, more lights isnt better unless u have mastered the art of doing the most from 1 1000w. You could try a 12000btu air con but ur exaust will stink also with the air con it dehumidifies the air so you wont need that. You can regulate your co2 manually if your n a budget

Are you sure the Ac will suck out all the co2?
A window unit or a portable dual hose AC should vent very little air out of the grow room. The only type of AC that will vent alot of air is the single hose portable units which would be a bad idea for a sealed room and window units if they are not set to recirculate.

Using Home Depot exactly like the OP and managed to get a older Telaire CO2 monitor for $130 delivered only to find out it does not have a power supply and now I have to figure out which adapter will work without frying it.

If you keep watching E-bay you can find a Telaire 8000 for around 200-250 possibly less in auctions once in a while and they are the same components that are used to make he Cap ppm controllers which go for double. Not to sure about this place but if you can get anyone to verify this Co2 controller: http://www.hydroinnovations.com/product5.htm
is any good it might not be a bad deal.
As far as cooling goes I have been thinking of a DIY version of the Hydrogen Icebox http://www.hydroinnovations.com/product3.htm
which looks to be basically a heater core with water running through it. If you were short on funds you could temporarily run it drain to waste until there was enough money to buy a chiller. I was personally playing with the idea of plumbing in a chest freezer with water inside it in a container that was outdoors as a poor mans chiller. Seen a guy using one to cool his aquarium and it might keep the water cool enough that exhausting cooltubes would be unnecessary. A split AC unit would be more efficient but cost alot more up front.

Cool, thanks
I am ordering from here
http://nationalgardenwholesale.com/ngw/gardening_supplies.aspx?request=pl17&type=subcat&title=Environmental Controllers / C02&pagenum=1

Those are what i have to work with right now,lotsa sentinal on there.hmmm
I do not know if you are in US or Canada but here is an ebay Telaire that is finishing Auction tomorrow if the price doesn't go up much more I will be kicking myself for not getting it.

Ah hector is so far off base. I havent even seen him post a co2 grow on the boards. i have posted many showing co2 tank setup, green air generator setups, timed release and pin point ppm controller releases.... hers another quote directly from the scientific data I posted earlier...

The biggest problem that people encounter when using CO2 is that they get carried away, they think that a little is good so a lot is better....NOT! When CO2 levels approach 2000 p.p.m. most plants will die. High levels of CO2 are also toxic to humans, primarily due to oxygen deficiency. Before injecting CO2 the room should be vented to remove excess CO2 that might be left over from the previous injection, this prevents the build up of CO2 that could harm the plants.

He must fall into the biggest mistakes made by users section./ Your right though on ebay you can get the teleaire similar to cap controller monitors for between $200-$325 all day long. You will notice most come preset to the industry standard optimal ppm of 1500 and most max out at 1800 as any higher is damaging. Get the portable ac unit at like home depot for around $300 and it will be best. Keep temps up around 80-85 for co2 usage and adjust your bubble meters to an even flow. A simple co2 tank setup is easiest and heat free...but what do i know Im just a hack who cant grow and owns a hydro shop soo guess these pcitures show my crap ability with co2 oh well guess I will go sit with the co2 tube in my mouth so I can be smarter

I'm running 120 plants in flower and 120 plants in veg. 2-3 weeks of veg and 8 weeks of flower. Veg room with 6 1000 watt lights (soon to be 600 watt) and 12 750 watt (acctualy 6 -600's and 6-750's but I'm moving the 600's to veg and adding 6 more 750's). I've got the Chhc-1 wich controlls all my nessasary equipment and a HydroGEN water cooled Co2 burner running on natural gas and draining to waste. I exhaust for 15 mins every half an hour for temp and smell. My room stays below 90F and I havent even needed to ir cool the hoods. I think I am going to stick a 1400 FKD on a filter in the middle of the room to scrub the smell instead of venting the room so often. Here are some pix of my Co2 set up...

I made another post but it must of been blocked because it was a double post. Anyway here is a Telaire 8120B-L that is finishing auction tomorrow:

http://cgi.ebay.com/Telaire-CO2-sensor-Ventostat-8102B-L-with-display_W0QQitemZ260418948596QQcmdZViewItemQQptZLH_DefaultDomain_2?hash=item3ca22dcdf4&_trksid=p3286.c0.m14&_trkparms=72:2067|66:2|65:12|39:1|240:1318|301:1|293:1|294:50

I do not know if you are in U.S. or Canada but if the price doesn't go up to much it would be a good deal either way and I would kick myself for not waiting and getting it. If you use E-bay it would be worth a try anyway.

Dual hose portable unit DOES have a minor pull from the grow room. It is noticeable. I'm sure a window unit is not 100% seal proof.

Split ac is the only real way to prevent CO2 from being sucked out.

I've spent countless of dollars on different portable/window units.

grow4profit,filthyfletch:Thanks for posting the pics,
So im now under the impression that a window a/c will absolutley not work?
And that they defintaly mix in/outside air..Heres a pic i found expaning a/c let me know if its wrong....
I will certianly keep an eye on the telair co2 cont,there price is very attraactive.

Fletch,grow4profit: Have you guys {or anyone else here} used co2 at high/deadly levels for say an hour or so,to controll pests ?
I read a CEA/CGE grower named bchardcore runs 1ok ppm for 1 hr to deal with pests organically...interesting.

Do you guys know if all magnetic ballasts are switchable to 24ov,I opened my ballies up and found a 24ov aswell as others.

I m setting up the second room today,back to work
Cheers HBR

I read this earlier in this thread but it seems way too dangerous. If 2k PPM can kill your plants and 4k PPM is harmful to humans, then 10k PPM seems way too dangerous. I would stick to spraying for pests. I just heard from my friend that GH has an organic spray (Azamax) that will kill anything and you can use it up until the day you pull. I would always stop any spraying 2 weeks prior to harvest. I'll see how this works for my boy’s crop. If it is good I would suggest a dose once every week or every other week as a preventative measure. Prevention is the best cure.

the method to kill insects using CO2 is to flood the room as quickly as possible, then exhaust it all out, lights off. And you shouldn't be in the room, obviously. Monitor the CO2 from outside the room, trigger the exhaust fan from outside as well.

It's not hard to do, technically, but if you're running a sealed room environment, non-soiled based, and your clones are clean, you shouldn't have any insect problems at all.

2000 ppm will not kill your plants you can go to 2200 ppm even a bit higher but i like the 1800 ppm range. blue ox 8 burner matador controller 2 fan 3 coil heatxcahnger dehumid at 55 percent connaseur b52 bud blood f1 overdrive big bud scorpion juice tarantula carbo load and some other little things. o ya 1500 ppm will not kill a human even if you were in there for all of your life till u were 80 lol idiot

wheni was cheap i ran co2 burner manually and left it on for an hour and i must of reached 30000 ppm in the room plants were ok so if you run 10000 ppm for an hour im sure it will be ok just have a timer hooked up for the exhaust and a timer for the burner so as son as the hour is up burner is off and exhaust kicks in just peak in and c to make sure burner is off and exhaust goes on but dont hang around the room until at least an hour of exhausting the co2, test ppm its safe to go into a room with 10000 ppm but some people might fell dizzy because the lack of oxygen so wait till 3000 to 5000 ppm before gong in the room. Ive never used this for killing bugs but i might try it out wont hurt the plants unless they die from heat stress but you are using co2 tank so they will be alright.

i should be impressed lol ur in a horizontal system running pasive hydro thru lava rock what do you yield a pound ? people are getting 3 plus per 1000w light out here some even more, we just dont like sharing this info to much with americans since they are canadas biggest client. makes sense doesnt it ?

85 degrees is just too hot. I run a sealed room, 20 x 8 x 8 tall, with a 2 ton wall a/c, a Hydrofarm CO2 bottle setup (I have several bottles of different sizes to swap out), and 3 x 1000 Galaxy digital ballasts driving Hortilux HPS bulbs. This setup grows a 60 station Bato bucket top-fed hydro (basket emitters), growing in Leca clay pellets. Clean, relatively low maintenance. This grow is done in a very hot climate (no, not Alaska).

Thanks for stopping by Alaskadood!
I have question reguarding your window a/c, does it mix grow room air with outside air at all? This is the deciding factor for me as a 24k btu wall/ac is very affordable,and i need to get one asap...Thks Hbr

I would comment but I have recieved a warning about arguing with new members and was told to leave this alone and let people do whatever they want.But i will say to Hector that if you think hydroton is lava rocks then thats enough said as a basic knowledge grower knows the difference. Yup i grow horizontal in fllod tables, ASero ponics setups, NTF setups, dwc, direct drip and the occasional soil. So yeah i showed you one grow. A simple $600 tent setup that flowers for 6 weeks yields 2-3 lbs dried with 20 plants. Of course we all knowone setup isnt all some of us do just as you do in Canada I assume yourself you run several grow rooms at multiple locations with multiple nute setup and multiple grow methods and not just one andcall it a stadium grow and thats it.And just as a disclaimer this is not a personal attack on this new member but a complete disagreement explained in response to his comments. And I hope the Canandians are thankfull that most of the strains and best growers were all MAericans who fled to canada during Vietnam to avoid the draft and took those US seeds and know how to you sooo basically thanks for letting us grow thier for free and take it back to the US and no need to thank us for showing you how to grow and giving you soem real nice strains its no problem when you need more help just let us know..have a good one

not my fault you american pussies had to run away from war. Us canadians we volunteer, we conquered normandy we defeated the germans we were 7 miles into france when you americans asked us to stop and wait for you guys. In afghanistan, the canadians are the best fighters, best kill ratio and every nation salutes them as they volunteer to go into the heaviest insurgent area near the pakistan border. Us canadians have made plenty more genetics since the viet nam era and we are the #1 producers of cannabis in the world. We have the best nutrients company in the world, we have so much oil gas water diamonds and land free untapped resources. So before you go knocking down your brother up north that sends you guys hydro for free, that sends you oil and natural gas on a cuff and lets you use our fighter pilots whenever you want, btw cold lake alberta fighter pilots have won top gun 3 years in a row from americans and israeli fighters. Hvae some rspect for us canadians cause we deserve it the whole world gives it to us its about time you americans start. O ya our beer is better, we dont go to jail for weed, and we have medicare for everyone. as for hydroton clay pellets used them hate the salt build up and washing them plus they get heavy when wet, im an aeroponics or dirt guy. here is a link from ed from hightimes regarding co2 lol http://www.cannabisculture.com/v2/articles/4772.html did u read that 2000ppm lol bwahhahahahahah thats from ed rosenthal from hightimes lol i sure he is wrong too lol

Oh i do like Canada I was just saying your welcome for us showing you guys how to grow and breed thats all. I know you guys offer your 2 dozen aircraft for helping when you can and yeah we appreciate you willing to dril under lake erie to get the natural gas source there that is mostly on our side of the border but we can't drill because of the eco nuts preventing it. Like I said i like Canada nice country has lot of good things it's just they got most of it from other countries thats all.. Im not gonna quote Ed on anything or else we have to quoite Jorge from high times too and he quotes 1500 ppm as optimol for co2 so thats a never ending point of who you like better.I prefer aeroponics myself as my prefered way to grow been playing with it for quite a few years now and find its best way to grow fastest and best yielding. Found the hydroton and rockwool combo is the best way in aero. better beer naaa, some ok ones but oo bitter. Never had a salt or nutrient build up with hydroton before and I tend to just was the hydroton in a washing machine cycle and walk away so not much easier then that.. Free health care would be nice but from the reports I have seen it seems to be bankrupting your country which is why it won't work in the US either even if dopey Obama wants it to..Like I said to each there own if you wanna live in a high level co2 house thats good and if you want to pump 2000-5000 ppm in your grow room go for it.I'll stick to my tried and try method which is the standard and be happy with it and you use your tried and try high ppm and be happy with it and everyone can be happy growers. To each there own but I have to stop and let this thread go back to its owner now. i apologize for kind of filling your thread here with the arguement...

ya well you said anything over 2000ppm you would die and i showed thats not true at all. Plants will die after 2400ppm after long extended periods of it and humans can stand 10000ppm in submarines for months at a time. So 1200-1800 ppm depending on stage of bloom is the correct co2 amount for an excellent growing environment. and no you dont die or get sick at 2000ppm, drowsya round 5000 and nausea at 10000 but studies have shown that the body seems to adjust fairly quickly at high levels. 30000 ppm might kill you depends on how long you are in there for.
