CO2 Humidity
CO2 Humidity
yes it will increase humidity, but use DeHumidifier LG makes a good digital one for setting levels, about 85 degrees is about right. a GreenAir 3 Generater and a C.A.P controller monitor . CO2 off when the lights go out. on when Lights come on. 1200-1800ppm setting , lower you run it longer it last 8'x8'x7' about 2 1/2 weeks on a 20Lb tank Room not air tight. Humidity about 35%.
The temp will usually drop 15-20 degrees at night. lites and gen off/ oscillating fan on all the time !. Gotta love Jan & Feb lol.

here is another question for u guy. do you turn your CO2 off when the lights go off. does that create a problem with keeping level steady or is it ok to le tthe drop while lights are off. i know that the plants use CO2 and light to make energy so is there any use when the lights are off or can the plant "store" the light energy and still use the CO2 for energy synthesis?Uncle Jesse said:yes it will increase humidity, but use DeHumidifier LG makes a good digital one for setting levels, about 85 degrees is about right. a GreenAir 3 Generater and a C.A.P controller monitor .

CO2 levels
CO2 levels
Plants, all plants breathe in what we breathe out and release oxygen so we can breathe ! I dont want to over simplify this but durring day time the plants kinda breathe in, and nite while there resting they breathe out. it's kinda like body builders working out is tearing down muscles, and rest and food build them up ! and the more you work that combo regularly the stronger they get. SO as long as the room is sealed (relativly) 12 hrs nite gives the CO2 time to Leave (disapate). if they vent they do it right before lights and CO2 come on, i would leave it fairly sealed just my .02 worth , I hope that made some sense to ya !
That C.A.P controller say its set at 1500ppm ok 1550 it shuts off and 1450 it kicks back on and on a timer its off when lights are off.
DO NOT GO ABOVE 2000 PARTS PER MILLION=PPM....IT KILLS MOST EVERY THING ! EVEN PLANTS.........READ.

They definately do,dont you notice that on your cap Uncle Jessee?Have you ever read the PPMs right when the lights come on?My room is almost identical to yours,8 by 8 by 8 with a cd-6 generator and cap controller,I'm usually around 2500PPM when the lights come on.It wont kill your plants dude,5000PPM maybe 2000PPM definatyely not.If I dont open my door for 15 minutes every morning,the PPMs will stay up there for hours.It takes about 3 hours to drop from 2500PPM to 1800PPM,thats a long time to basically waste!
would any of you guys that have worked with CO2 for awhile be willing to write a guide on how to control the level to suit your needs ie. controlling levels, turning off when the lights go off, regulators. all the stuff that you need to do CO2 right. im sure alot of us know the benefit of CO2 use but dont know the details of how to use it.

Ballastman i have been getting into a habbit of closing the valve off at night and relighting in the light hours, but it sounds like your room is sealed tighter than mine,
i do however notice it does stay around 750 without CO2 on. your cd6 has what one or two more burners in it so with the pilot light going that mite be the reason the levels stay so high, .................1800 is THE HIGHEST i would go period. no maybe 2000ppm won't kill your plants but it's not doing them any good either kind of a waste. and if your in the room long enuff it could hurt you ! your plants will be fine when the Coroner gets there, I am not trying to flame you or nothing but its a big safety issue ! peace.
Do a search for
GreenAir.com go to generators
C.A.P ppm 3 controller/monitors
maybe this will help

"The concentration of carbon dioxide must be over about 2% (20 000 ppm) before most people are aware of its presence unless the odor of an associated material (auto exhaust or fermenting yeast, for instance) is present at lower concentrations.
Above 2%, carbon dioxide may cause a feeling of heaviness in the chest and/or more frequent and deeper respirations.
If exposure continues at that level for several hours, minimal "acidosis" (an acid condition of the blood) may occur but more frequently is absent."
Taken from
http://www.inspect-ny.com/hazmat/CO2gashaz.htm
in fact current guidlines allow for up to 5000ppm of CO2 in a workplace, and their thinking of upping that to 10,000ppm.
The plants won't use much more than the 1500-2000ppm that we're giving them, that's the only reason we keep it at that level, you'd have to have almost 10x that concentration and be exposed for several hours to start having adverse reactions and even then you have days and even weeks before any serious reactions occured.
hell in my space my PPM routinely go over 2000ppm when I'm in there and will hover between 1450-1600 when I'm not.

Thanks chaotic thats good info,I'm in my room for 5 or 6 hours once every 5 days and the PPM's are between 15 and 1800,I know this would have to double before I'd be concerned at all about it.Co2 can be dangerous,but not the levels we mess with.

I use a green air cd-6 propane generator about 450 bucks and a cap3PPM controller about 500 bucks

Uncle Jessee I notice you set your cap at 1500 like I do,I know my generator kicks in at 1450 but didnt know it kicked out at 1550,just never hung out to watch lol.Most of the time I go in the co2 is over 1600PPM so even though it kicks at 1550 the co2 and cap will still keep rising for awhile apparently.

Man I have seen plants get bleaced,reductions in yield,I wish I knew where that thread was at where that guy had to disconnect a few of his 600s,then he got much better results.I'm not saying it may be cool for some strains,for many it may not be.I run 50 sq ft with vertizontals and if the seedplants get too tall,I'll have major bleaching on the upper fans.100 sq ft would turn them to albino's.Think about it man you'll have to keep the lights up pretty high to avoid bleaching,then you have problems with stretching!I think the 50W sq ft. is in stone because its the most benefical lighting you can give cannabis.I know you've seen successful grows at 100 w sq ft at least you say you have and I dont doubt you,I just wonder how common success is at that high a brightness
