When can I introduce CO2

Hey everyone, just planted 5 feminized white widow seeds a little over a week ago... The temperature is a little high (81-87), esp. after putting in a 250W HPS light in, and I've read (i think) that if CO2 levels are high then the temperature can (and should be) higher than the normal 70-80 range... so my question is if CO2 can be introduced to the plants when they're so young?

Since i'm posting i'll go ahead and ask some other questions:
1) cheapest/easiest/safest (for the plants) way to get rid of some little bugs (look like gnats)?
2) in reference to the high temps. - right now there's a fan positioned on the wall above the light fixture, it points directly on top of the light and the air moves around the bottom (enough to give the plants some incentive to strengthen their stems). should i move the fan (or get a new one) to point at the bulb? how much should that help in the temps?


Thanks a lot in advance for help on these questions - i may post some pics later so i can get some feedback on the set-up

look up ducting, your gonna need more lighting than that unless your using 6 sqaure feet. co2 will increase your growth at any stage. it promotes photosynthesis

CO2 is not used by most growers during vegetative growth, we want the Buds to grow, not the leaves. Start high levels of CO2 1-2 weeks after you start flowering. 1500-1600 PPM level of CO2 is most efficient.


Cheapest easiest safest? thats an oxymoron. You can't be the cheapest AND the safest AND the easiest all rolled into one. You get to pick one. IMO plain old Neem oil works really well, its safe to use all the way through flowering, its fairly cheap, but you do need to spend some time to properly apply it. You may have to apply multiple times to make it work 100%. There are other things you can do too, but I would reccommend you actually identify the bug. If its spider Mites you might be doomed if you can't kill the lil fuckers quick enough.

no you've got it wrong, CO2 promotes photosynthesis, photosythesis has nothing to do with leaf growth chief it has to do with how fast plants absorb and proceed light. a plant works best at 1500 PPM PERIOD. A CO2 tank can double your yeild by makin buds denser, faster and speed up vegging growth up to 5 times!!!!!

Umm no I don't have it wrong. i actually use CO2, do you? I run a 1600PPM mix off bottle. It doesn't promote photosynthesis, its one of the essential ingredients for photosynthesis. You can't have plant growth without a commensurate amount of new leaf matter because its the actual leaves that do the photosynthesis process. You don't see any leafless plants out there growing only huge amounts of bud do you? Stems and flowers are not involved in the process of making food for the plant. The stem is the highway for nutrients and water/waste to move about, the flowers are the unborn children the plant is so desperately trying to find the pollen for to make viable seed and thusly ensure its genetic survival.

CO2 will never double your yield, that's scientifically unsound to think that, it has NEVER doubled my yield. You looking at a 20-30% increase which is a far cry from 100% increase (Doubled). It now takes me 3 weeks to grow a 24" plant from a 6" clone, your saying I could actually do that in 4 days if it grows 5 times faster. I am not sure what planet your from, but here on earth only bamboo will grow that fast. I will just for shits and giggles give my plants 4 days of co2 during my beginning of the next cycle in 10 days, so in 2 weeks we will all know if that claim of 5x faster veg growth is true. ...we all know its not true at all.

first off LMAO

WHat does that look like? Maybe it's a CO2 tank with a regulator. I probably just shove that 200 dollar regulator up my ass for kicks everynight cuz it helps me sleep better
i've seen growth up to 3 times faster, i'm not pulling these numbers out my ass. number 1 you dont have a way to measure the ppm everytime it falls below 1600ppm or whatever. number 2 you dont know how fast your room is leaking. and you can't even use a clone as an example because it's stunned for 10 days anyway. number 3 CO2 does not concentrate solely on leaf growth, leaves are mostly a source of energy and the plant uses a lot to make the bud. the CO2 helps the plant produce whatever it needs to at the time and it just happens to be when the plant's still growing if you know anything you know that during flowering your not supposed to run the tank at night, because the plant doesn't need it which is actually when the florigen hormones are active

Hey Guys, I have a question for you down these lines. I am using a hydrohut and carbon filter running though my hood to keep it cool. If I add CO2 during the daylight hours the fan is constantly sucking my CO2 out. The fan is only off when the light is off during flowering. How can I add CO2 during the light cycle?

Im pretty sure if he has a monitor then he cn figure out exactly how long it will take for the room to leak back down to 500ppm or so and adjust his co2 acordingly. I would have to agree with drama on this one. the idea that co2 will make EVERYTHING better and things grow twice as fast is over stating it. co2 helps a great deal in all around plant growth but adding co2 is not going to double anything unless for some reason every single thing your doing is absolutly perfect and co2 is the only thing holding you back. and even still it is doudtful to get a 100% increase in growth.

You pulled those numbers out of your ass buddy, no where on this earth will you double your yield vs not using CO2. and yes I know exactly how much PPM my setup is set to keep it, thats why you use a controller, but it doesn't look like you have one of those. My setup is completely sealed from the outside world, so no CO2 escaping here.

I am just going by the facts, not MJ fantasy land. FWIW florigen hasn't even been proven to exist. We call the hormones that induce flowering Auxins.

Shoving that co2 regulator up your ass isn't doing much good there, maybe self fullfilling fun, but it won't help your grow any. BTW what kind of solenoid do you use?

Your plant will always be able to use co2 people .it might not double but it will make your plant grow faster and stronger. Go back to science class and ask you 4th grade teacher tghat, and she will tell you about trees and photosynthesis.

actually i'm getting my information from this book and i refuse to take a picture of the page i'm looking at


http://www.erowid.org/library/books/images/marijuana_growers.jpg but fine, you know everything apparently, you win i really don't care at all.
the last controller i saw was like 800$, where can i find a cheaper one? the solenoid i have is hydrofarm. active air co2 system

I read that book a few years ago, it doesn't say CO2 will double your yields, it says 20-40% increases. Even Ed would not dare make such a bogus claim.

I don't know everything! But I do know falsehoods when i see/read them. Your using the same solenoid as me. a 50 pound bottle lasts for 2 flowering cycles on my system running at 5psi regulated.

Gotot Your setup looks really good, you should start a grow journal or put up more pics for us all to see. I am interested.

ed said and i quote"Adequate amounts of CO2 may be easily replaced in well-ventilated areas, but increasing the amount of CO2 to .2%(2000 PPM) or 6 times the amount usually found in the atmosphere, can increase the growth rate by up to 5 times"


this is my first grow ever

Is that a window AC you have piped into your grow space?

Plants look healthy, Is there 2 kinds in there? the ones on the left look very sativa with the long fingered leaves, and the ones on the right look more indica dominant. What strains you growin?

there's no a/c just a box fan blowing into a vortex(dual twin fans are out f season, got to order one) :cry: but it's cold, i just put my plants into flowering today :mrgreen:, the temps where 94 deg:fire: and 70 perc humidity, that wil change the deeper we get into winter thank god:blsmoke:
as for the plants, got 2 from bagseed and the others from apparently exo(suspect because some were sativas, others indicas) there's mostly sativas(i have 9 in the room) and i tried the LST method about 6weeks into growth and the main canopiies are real strong. the grow shoots that replaced it came basically from the base. i know i'm going to have space problems because i can't really raise that shelf. do you have any ideas>

those pics are from wedsday and they've gotten about 3-4 inches taller

$800 for a controler? Yup. also $350. Can get a new car for 15K and also 65K.

My controler is basically a DIY.
A G.E./Telecare monitor that has temp and ppm out put via RS-232 and analog. Dumped the analog into a A/D converter plugged into a PLC that controls *everything* Fans, lights, watering, CO2, etc. One brain, no confusion. Full set up is probably $900 controler-wise with a touch screen IF.(add for lights and pumps) And I can control and adjust all from the road 1000 miles away.
