Umm this has NOTHING to do with this debate. And is NOT referring to your previous statement saying plants dont use co2 as humans use oxygen. Please correct your self and do some research :) Im off to dinner have a great thanks giving. Hope you learned something new today take care friend. Also seriously Wikipedia? Im not sure if you've even been to college but try using that as your source LOL :/ good luck

haha I never even said that man. I said plants don't use oxygen like they use co2, which is what you said. Anyways I didn't learn a god damn thing from you and you are pretty insulting. I have nothing to prove to you man, obviously you feel as if you have something to prove to me. I do have a college degree but looking at your grammar and syntax I'm fairly certain you do not. Wikipedia or not, it is a good explanation of photosynthesis! You should read it! Ok, take care have a good thanksgiving. I've offered my 2 cents on this matter.

That you didnt learned anything from the mass amount of information given well im sorry that's you fault. Didn't mean anything personal by anything that was said and i do hope you have a great thanks giving. My grammar and syntax hehe :/

to answer the thread as simply as possible and sorry if this has already been posted, theres so much idiocy going on in here that i didnt read most of the thread.

the reason you stop co2 during the last 2 weeks is because at 2 weeks until harvest, your buds are no longer producing new resin. the xisting resin is now starting to mature. continouing co2 supplimentation would just dilute the thc content of your buds. cut co2 when you start your flush, or maybe a week in if you do a long flush.

and dont start your co2 until have the "jump" is done when you switch to 12/12. keep it at 1500ppm when lights are on only on the week when you fed nutes, on the off week its ok to drop it down to conserve.

if you use co2, you have to keep the room humid, and at around 85-87 degrees for full absorbtion.....this also means using a dehumidifier and air conditioner to drop the temp and humidity during the lights off so that your big beefy buds can remove some moisture, and kill the threat of mold, and it also makes the environment unsuitable for mites. thats huge because a hot humid room with lights on will most def attract the mites

thansk bigmoe. I am on vacation but I will post the co2 schedule I saw in maximum yield. It made allot of sense. Low during the first couple weeks, higher during the later parts of veg and highest during the middle of the bud cycle. They dropped it to like 500-600 during the last two weeks. Been trying to tweak my room to get the higher temps and higher humidity when the lights are on. If my temps are in the 80's then I want my humidity at least in the 70's as I know it is stressful for plants to have high temps and low humidity due to increased vapor pressure differentials. This large difference between the moisture content of the leaf and ambient air can cause the stomata to close up to limit moisture loss, thus limiting co2 intake.

Well if I thought any of this would give me 15% more yield I would change tomorrow, but I won't. I'll keep running my little house the same as I always have.

Couple of comments, you guys keep pissing on each other and we will get the answers, eventually. Thanks for the refresher course Cool.

If air is stagnate in a grow room plants will use up all available co2 around the plant in under 2 minutes. Fans and ventelation...

Most people who use co2 do not get the benefits because you need to have the other 5 [FONT=&quot]essential elements [/FONT]dead on for it to work at max. [FONT=&quot]Growers must control six "essential elements" - air, light, nutrients, water, humidity and temperature. Remove or alter the ratio of only one of these elements, growth will slow, and plants could eventually die.[/FONT]

Master the 5 [FONT=&quot]essential elements than use co2 and you will get 20 to 30%+ more.

Have at her boys yeeeeehaw :blsmoke::bigjoint:

Upwards of 1500 ppm is ok! Existing setup is blasting with 2k HPS 84 deg and 2200ppm water with 2k ppm co2+. Ak48 in flood and drain. Would post pics but got an uptight partner. 19" colas bigger than a soda bottle round by far. All botanicare nutrients. Lights on movers. Water 69 deg. 15 deg dif night and day. No cropping techniques, no burning. The point is if your strain is hearty and your conditions are right, and you've got balls, you can push the envelope and come out with something truly amazing. I'll try and snap pics next time I'm over there...don't hold your breath, it's 400 miles away.

It's about time someone else besides myself decided to grow pot the correct way!!!

In otherwords do not create negative pressure in your op when using ventilation.

Its not pressure actually. Its a vapor moisture concentration. Just like heat migrates to cold, wet migrates to dry. Same thing as holding the edge of a paper towel in the water and watching the whole thing get soaked. Anywho, I knew what you meant. But yeah, you shouldn't have a negative pressure in your room either.

Hey learning, what is your humidity at?

Here you go my friend please read this and highlight the part were it says co2 changes the taste of the plant. Not arguing here and sorry if it came off as i was. just trying to debunk your misunderstanding :)

I’ve never noticed this. Just had a run purple Afghan ran co2 all through out flower. Even had to flush rather quick still ccsme out tasing like pineapple gas. I am wondering myself though about ideal times to cut co2 in peak flower and this thread is borderline helpful
