New Co2 Method !!!

[ItsGrowTime]

I always thought plants breathed in CO2 and released O2?
Did I snooze through the biology class lecture part about plants giving off CO2?

Scientific fact?Man I dont like when people come off like they know what they're talking about,when they dont.It only confuses others.Here is but 1 link if you'd do a google check you can easily find out if plants produce co2 at night.Try googlin before you give false info bro.I didnt have to google though.I have a damn controller that tells me Pff.http://www,biotron.uwo.ea/news_gases.html

Shit,google plants make co2 at night and find it for your damn self if you cant believe what people tell you.What am I doing here anyway?

 

[Truth]

Truth keeping it all in the room is not all thats necessary for co2 enrichment,the most important aspect is keeping a steady PPM level that doesnt fluctuate more than 300 PPM.When I get up in the morning at the lights come on in the flower room,I'm usually at 2500PPM.You want to bring this down to around 1500 and keep it there,between 1500-1800 is what I find perfect.Lets see you do that for 12 hours with yeast,its not going to happen.I've grown with co2 for about 3 years now,first my portable AC shot it all up into the attic,then I found out the cyclestat timer I was using didnt really keep a steady PPM and I was ODing the plants especially in the morning.My whole last grow almost was done with a generator and controller finally instead of cyclestat,what a huge difference.I never figured they would grow this fast and flower this quick I'm totallly freaked at what co2 can do when everythings right.Without 50 w sq. ft I wouldnt even bother with co2.

if your co2 is escaping fast enough, you will not be able to maintain PPM's. your idea of keeping a steady ppm level is not completely correct. imagine if someone with a DWC had a little hole in their bucket, you would lose water, therefore you would require more sooner since it is leaking. if you open the door to your grow room, Your PPMs will drop dramatically. you can ask any expert, co2 only works best in sealed rooms, otherwise you have to use alot more, you are essentially wasting because the co2 is allowed to leak out. if the astronauts in the space shuttle had their oxygen leaking, but still had a steady supply of oxygen that could allow them to breathe, they would live, but they would also run out MUCH sooner. The only reason you would want to vent a room is from heat or too much co2, otherwise, keep all of that co2 in. you can setup yeast to release co2 at a fairly controlled rate.

well after a little googlin and looking round the net i have to agree with ballastman about the nighttime co2 thing. found this site for example http://www.newton.dep.anl.gov/askasci/bot00/bot00191.htm
seems like plants do make a bit of co2 at nighttime and if of course your plants are in a small enclosed space, like ours, then its going to build up.

 

[Truth]

plants make oxygen by day, and co2 by night...not anything new or unknown...or you could think of them as taking in co2 during day and oxygen at night.

Saying not doing CO2 until everything else is dialed in is like saying don't get the rH set right until you have everything else dialed, or like saying don't get a 1000W until you have everything else dialed. It's bullshit. If you are competent with systems both electrical and mechanical, and you trust your own abilities, i see no reason not to start with CO2. I certainly did, and I have had huge buds from my first grow. Honestly, the science is so real and sound, there is literally no debate. Why not do it if you can? High CO2 levels will give your plants lots of one primary food--CO2, and as long as their other primary foods--light and water--are plentiful, you will increase the yield AND HEALTH of your plants. Those 3 things matter most, along with rH and temp; nutes, which we spend so much time discussing, are just the condiments in the meal.

I have read that you can't really take advantage of a 1000W without co2, and I believe it. I have my 1000W 12" from my plants, with no burning at all. Without plentiful CO2, they could never process all the lumens they are getting, and they would turn yellow and burn. They are green and vibrant--they love it. And they generate giant buds; i have never seen TW nugs as large as mine, although i presume it's out there. And if i ever see TW that compares, I can guarantee it was grown in a room pegged at 1500 ppm CO2.

I would use the mushrooms if i was doing a closet or cab grow. Shit, it's dead easy. And even if it only takes it up to 800ppm or something, any increase is beneficial, albeit less beneficial than the 1500ppm max that cannabis can absorb.

"If you open the door the PPms will drop dramatically".Have you ever seen this in practice?.I know exactly how fast the PPMs drop with a totally open door,and it aint that damn fast lol.I'm talking about sealed rooms like mine of course,I dont know where you got the idea I vented.If your PPMs fluctuate more than 300 you arent doing your plants any good thats what I know from experience.If you're jumping from 2000 to 1500 to 1000 back up to 1500,you're just spinnin your wheels.My idea of keeping a steady PPM level is correct truth.

 

[jojajico]

a quick question guys. i would love to use CO2 on my next grow but it will be a closet grow with a 600 watt HID and i will be shooting for 100 watts per square foot excessive i know but i live in a world of excess. so it will probably be a 3 X 2 X 6 cabinet. now with all that light in a small area im going to have to ventilate. how could i iccoporate CO2 without just sucking all of it out. i considered fans on a timmer that would turn off and CO2 would then be turned on but i wouldnt be able to keep it at 1500 ppm. any thoughts suggestions ect. thanks guys

Bree: So the best bet would be to breed rats and grow in the same room! Cool, I am almost there with all the rats we have lol.

But ya, I see what you mean. Joking aside it could increase it enough to benefit the plants. It reminds me of a science project I seen on TV years ago. They had a completely closed off eco system and in one side had vegatation and in the other were mice. The plants were supplying the mice with enough oxygen to thrive, and the plants enough Co2 for the mice to survive. I think they had some insects also scurrying about that fed the mice so that no human interaction was needed for well over a year. It was a large system but not much bigger than a big bed room. It was really amazing to see how possible this can be. I wish I could remember the details. I think it was for showing the possibilities of life on the moon in human built mini eco systems. Anyone saw this too? It was on TV probably three or four years ago - you know, one of those science programs at eight in the evening.

One suggestion,let go of your crank!Your gonna bleach your plants and do them no good with 100W sq ft in a cabinet,I said leggo of that thaing!

 

[Core]

have done some rechearch myself on the matter....and used it...i might have some recepies these are diffrent in co2 release...if i can find them that is...gonne take a look
i'l post them for input if i can find them....

 

[Guest]

LOL mrgrowmez thats the first link I pulled up too,but if you look at it,she's asking the question.Believe me there are a lot of other links saying plants definately produce co2 at night,despite what some 20 year growers with advanced degrees have to say lol gotta love this place I think?

 

[THCV]

ballastman, i agree, just opening the door doesn't do much. Propping it open while working a lot will drop my room down to 1200 from 1500.

 

[Guest]

I prop it open every morning to get my PPms down from 2500 to around 1800 and it takes awhile,its not what I thought it would be at all.I have to laugh now,all the times I opened and closed the door real quick thinking I'd lose my co2,I grew without a controller for to long just a cyclestat timer to determine frequency and duration of burn.It wont keep a steady PPMs for shit.

Absolutely THCV i agree 100%, CO2 is a great addition which even beginning growers can utilize......you are a fantastic grower and highly educated and experienced and I really got to thinking about this sentence:

"Without plentiful CO2, they could never process all of the lumens they are getting, and they would turn yellow and burn."

Definitely injecting CO2 builds up the leaf tissue and boosts the plant's immune system so as to resist yellowing and burning. But that got me thinking, does injecting
CO2 turn on certain genes in the Cannabis plant which would have otherwise remained
dormant in a low-CO2 environment?

20,000 years ago CO2 levels were quite low on planet Earth, around 180ppm, compared to the 1500 ppm which is the target for CO2 injection.....it is interesting to
think about how plants evolved and adapted during this time.....

There is no toxic limit for CO2, unlike nutrients.....my research with medical grade
oxygen containers indicates that there is no toxic limit to the amount of Oxygen in the
medium as well- so you can see how roots and shoots are very similar in that they are
adapted to absorb as much gasses (O2 or CO2) as possible......although there is no
toxic limit to these gasses, there must be a point at which the plant just can't take in
any more CO2 and so above a certain limit would just be wasting CO2.....

Has anyone noticed a difference in fragrance/THC gland distribution/quality of the high/internode spacing?

(I'm searching the web for genetic effects of different CO2 concentrations)

ive seen plenty of grows at or above 100watts per square foot.

Thanks, gp, I am blushing.

The reason CO2 prevents yellowing/bleaching with lots of lumens isn't because the plant has a better immune system. The CO2 def helps the plants fend off bugs--using another metaphor, CO2 is like the protein for the plant, and if it is eating lots of this protein it will be healthier in every respect. But the reason you can put the bulbs closer with CO2 is because the plant is literally growing faster. Without CO2, but with lots of light, the plant tries to process all the lumens but fails because it runs out of CO2 around the leaf (circ fans be damned, this is at a microscopic level in microsecond time, hence the need for measurements in ppm, not cu ft/hr), so it bleaches-- photosynthesis stops when CO2 runs out, and now the photons are just burning the plant (aka transferring energy as heat rather than creating carbohydrates through photosythesis). But with enough CO2, the plant produces more vegetative matter (in veg/stretch) to help with the high-lumen processing AND it can process the light more continuously due to the high availability of CO2 around the leaf (aka high ppm) so it stays green and grows fast. This is why you need higher temps with CO2, because the plants can speed up all their processes in higher temps, and the CO2 supports that speed up, in the presence of enough light. I guess that explains why it speeds maturation as well.

Highly educated? Of course, because everything i know I learned from Jorge Cervantes.

 

[THCV]

as for a CO2 limit, it does appear that cannabis can't process more than 1500ppm, no matter how much light you give it. I believe this is variable for different plant species. Who knows why they evolved being able to process 1500ppm? But it sure is a great thing for us indoor growers! Maybe we can one day genetically modify cannabis with the gene from a plant that can process 5000ppm CO2, then imagine the yield increase!! Flower in 2 weeks! :wink:

Ballastman.......

Ballastman.......

Am a bit embarrassed. You were definately correct on the CO2 at night by plants. I did do some research. My main education is in the field of human physiology. Just wanted to let you know I am not too proud to say I was wrong. Appriciate the schooling. Will have to give ya some rep points for that.

Doesn't the CO2 still help a great deal even if it fluctuates from 1500ppm to 2000pmm? I can keep it up in these ranges but with the yeast I can't keep it as steady as 300ppm difference. I have not worked on it that way at least. I will have to do some work on that.

Peace
