The F.A.C.E program,understanding co2

[Guest]

There seem to be multitudes around here that just dont understand how co2 works and are wasting their time with all these fly by night idea's.No offence should be taken because I wasnt born with the knowledge,everyone has to learn about it.If you use co2 enrichment,you should thoroughly read the F.A.C.E program studies about global high co2 PPMs,and the results that will occur to our crops.It stands for free air co2 enrichment,although we use enrichment in a closed environment,this study will really set you straight about just how co2 works.Try googlin FACE program

typing FACE program in google doesnt bring up anything typing out what it stands for does. next time you may want to provide a link as i think more people will respond to your post. but thank you for the info bellow is a link http://cdiac.ornl.gov/programs/FACE/face.html

I know I'm lazy with the http's lol,I count on the assumption if you're smart enough to successfully grow erb you know how to use google lol.You're right though

By the way when I set up my cap in the backyard my PPms were over 550,I live a quarter mile from a major highway I think thats part of it,or co2 levels really are rising like a mofo?

Ah yes global warming The Co2 growers use aint nuthin compared to all big industry shit destroying our environment......

 

[jojajico]

maybe someday they will figure out how to store the CO2 we emmit and use it to increase yeilds in our crops. i always immagined that eventually we would develop huge air scrubber plants that like giant air cleaners would clean the air. maybe i watch too much sci fi channel.

ballast, what exactly do you want people to learn from this?

 

[Guest]

A lot of people know nothing about co2,I sure didnt when I started out.Parts of this study enlightened me quite a bit actually,its not mandatory man whats your problem anyway?

see his little man? he's brooding!

Have another hit! trust me, it's solved many a dilemma around these parts . . .

Actually if you read any,you'd know spidermite's increase with increased levels of co2,but you dont need to know things like that.Fuck,time to break out the NPS havent had mites in flower in a long time.Catch em at the first sign of spotting.You also want to kill the dehumidifier and turn the AC down all the way during dark hours

I've read alot about the F.A.C.E. program, ballastman and

It suggests that there is no signifant benifit from increased CO2, to plants in their natural enviroment. This is because of limitations in the avability of water and nutrients in natural enviroments, CO2 is not a significant limiting factor. In a grow room, where we can control the amount of nutrients and water, CO2 can become a limiting factor, and supplementing CO2 levels will increase growth until the next limit is met.

In terms of the enviromental damage cause by using CO2, if you want to be enviromentaly sound, stop growing under HID's. Really. The energy and greenhouse gas cost of electrical lighting is far, far higher than that of a propane/nat gas CO2 generator.

Also, if you are growing in a closed room, there is no net release of CO2 into the atmosphere. The plants consume all the CO2 and exhale it as oxygen. Ignoring for a moment the enviromental hazards of HID lights, the plants will also convert all the CO2 you exhale into O2, thus negating your personal impact on greehouse gasses while you are in the room.

Why do spidermites increase with more CO2? They breathe oxygen, and more CO2 means less O2... I suspect it has more to do with the temp increase that many people allow when they are running CO2. Right on with the dehumidifier, mites love it in dry enviroments, and they thrive on high temps, so cool night time temps will really slow them down.

Thanks for the info on F.A.C.E., ballastman and jojajico

It didnt explain why populations increase at higher co2 levels,just that it did I doubt they even know why.They expect spidermites to be a major issue in the future with increased co2 levels.

 

[Truth]

co2 causes heating in the atmosphere, so it is possible the HEAT makes ir more suitable for them in some regions...however, I don't think there will be any concern for a world wide outbreak. An the amount of co2 you use in the grow room is nothing to what you use with cars and everyday household items that run on electricity. However, CO2 in any level above norm will increase plant growth accordingly. Just as CO2 in low levels will decrease, but 1500ppm seems to be the safe limit. but it doesn't necessarily double the rates or go much beyond that, because 1500PPM plus is about 5x the amount of 300PPM said to be in the atmosphere (of which im sure it is more around 600ppm) but you won't see 5x the growth rates.

I havent had a spidermite outbreak in veg in over 3 yeares ever since I starting using a cool mist humidifier in the veg stage,its the best natural mite preventative available.If you get one spend an extra 10 bucks and get one with a visable mist,if it doesnt have a visable mist it isnt worth using.

 

[GirlWonderGrows]

I agree ballastman, I spray the veg and flower with a hose several times a day, I havn't had any visable spider mites in the veg in a while. The flower is another story... Unfortinatly because of where I am and what is happening I'm forced to simply try and constrain the mite population, there is really no hope of eliminating it. I'm in the process of constructing a closed room that will hopefuly be a mite free as possible. I guess I'll have to rad the FACE litrature again and find the bit about spidermites. It really dosn't make sense from a resperation standpoint, it should be harder for the mites to breathe, so it may well be another factor. Perhaps the plants grow more lushly, making a better habitat for the mites. Or something with humididty. Or perhaps the mite's predators are more suceptable to CO2 than mites, giving mites an advantage in thoes areas.
It would be important to know, because some conditions we can alleviate in a controled enviroment (like humidity) and some we can't.
