Co2 decreases THC?

I've heard good things about using Co2 but I heard "High Times" published a report that Co2 can decrease the THC level and potency of the plant. Any truth to this and is it recomended to not use Co2 two weeks before harvest?

wow man never heard of decreasing the THC... If HT wrote it then I'm sure there is some truth behind it. I was always told by using it you were able to flower in a shorter time and increase the size of buds.. Quite interesting and a very good question. I will be watching to see what others have experienced....

I don't have any facts. I just did a google search on growing and use of CO2. Under this growing guide it cited a HT report stating that their study with co2 revealed lower THC levels. I'll try and find it again and post link.

Basically, when plants grow, there growth will be limited by one factor. This is usually CO2 levels. If you increase the relative levels of this factor, you will increase the rate at which the plant can grow. This can be light, CO2 or H20, any of the three things plants use to grow. Does more lighting increase the speed bud matures at? No, it only increases the plants ability to grow. So, CO2 wont do this either. Its like, giving a child more food and hoping he will reach puberty faster, aint gonna happen.

Here is the link Cannabis Growing Guide Part 8

"Most closets will need new CO2 coming in every two or three hours, minimum. Most cities will have high concentrations of CO2 in the air, and some growers find CO2 injection unnecessary in these circumstances. Some growers have reported to High Times that high CO2 levels in the grow room near harvest time lower potency. It may be a good idea to turn off CO2 2 weeks before harvesting".

Any truth to this?

Any opinions?

It's possible that the average person would not know that THC levels are actually decreased with Co2 through harvest.

Yes, it fux up the THC production to use excessive co2 during budding, and it is for much the same reason that you use red or blue....---There are correct times to do things when vegging or flowering, or then again you could do worse with your timing and efforts.
Now, what is really gonna tweak your noodle is understanding how it could be possible that chopping the plant down and sticking it in a bag with some dry ice would make it more potent........or, does it?
You should consider that co2 can increase growth by, well........I have grown wheat 6 inches in one night using co2 enhancement....and consequently you will have a bigger root ball with a bigger plant with MUCH BIGGER BUDS. I would recommend growing without the co2 for a couple weeks or so for any plant especially that which has nutritional value. In fact, the plant, any plant, is likely deficient if you grow with co2 and don't give the plant opportunity to use the sugars it produces to build up the plant and other such groovy stuff.....leading to dumb stuff like week nutritional value and flimsy stalks. If you think i am kidding, just look at the nutritional value of corn and compare it with corn from 100 years ago. Thats right. You are basically eating nutritionally sub standard corn....which has become the standard. Apply this concept to your growing.
HAVING A BIGGER ROOT BALL, for soil growers, MEANS BIGGER YIELDS. Thus......when you are done budding and collecting your yield.....KEEP THE PLANT!!! send it back to the minors and let it vegetate 'till you are satisfied with the height and get a bigger pot for the soil and you are in like Capone while you GROW A SECOND, AND BETTER, HARVEST WITH THE SAME PLANT and will likely offer a much better yield. Go gangster on them bitches.
You should also consider that if the plant is growing up very quickly that MOST OF THE WORK GOES INTO VEG PRODUCTION INSTEAD OF BUD PRODUCTION so don't use the co2 when budding. duh. One could argue that if vegging techniques/processes takes away the food for the buds, then at any time during the flowering stage that you concentrate resources to grow the plant, you will take away food from the bud....sorta like like growing up instead of out. Ask your self if yo want the plant to spend more or less of it's time making buds??
This could all be bullshit. Who knows, but maybe the c02 is actually inhibiting the uptake of an additional and important flowering nutrient in much the same way that a drug might not work if you are using something that blocks it.
I hope this helps and offers new ideas to you.
God bless America.
