Myth busters - the real truth on CO2 in indoor grows

Ok, since you still seem to want to stand by this post, here are my specific responses.

Myth one: I personally would think it a bit obvious that a mostly sealed environment (relative to the outdoors) with a bunch of entities exhaling co2 all day would have elevated co2 levels. Just saying.
Click to expand...
not obvious at all and missed by many. Check out the co2 stickies on this site -for instance the calc your co2 in indoor growing forum and it references - *The air already has about 300 PPM so you only need to add 1200 PPM more to get the optimum level of 1500 - where 300 ppm is a low value for outdoors instead of using 600 ppm indoors. You are wrong and this myth needed de-bunking.



Myth two: My biggest gripe here is that you failed to mention the most important part about co2 and plants. The levels need to be consistant.
Click to expand...
still looking for you to back this statement up with some sources - especially as it relates to variations in concentrations between 1200 ppm and 1500 ppm. I have found absolutely nothing to back up your complaint.

After that my gripes are that you have the target amount wrong (usually 1200ppm since the other factors have to be dialed in so precisely that it's an impossible threshold without uber serious money)
Click to expand...
as I've said earlier my target has been to stay in the range of 1200 ppm to 1500 ppm.

and that you suggest providing a constant supply of co2 to plants isnt beneficial unless you have everything else dialed in. This "dialing in" of the other factors becomes proportionally more important as you reach higher co2 concentrations, and the reverse is true as well. Ensuring that your grow maintains a nice 800ppm concentration of co2 will always improve your grow unless you are completely inept or incredibly lazy.
Click to expand...
can't for the life of me figure out what you're complaining about here - this part of the thread was meant to warn away newbies who thought they could just add co2 and see a benefit - how would you say it differently?

Myth three (FYI- this is the myth that you have to actively bring in air to a small indoor grow to replace depleted co2): This is just basic common sense.
Click to expand...
really? I won't even bother to reference the hundreds of times someone brings up the need to bring fresh air into a small indoor grow room. Again, you put down things as common sense when there are a lot of people who believe otherwise. You are wrong again and this is clearly a myth that needs debunking.

Myth four: Activated carbon is merely a process of changing contaminants from a gaseous phase to a solid phase, when aggravated or disturbed contaminants can be regenerated in indoor air sources. Just saying that it removes smelly stuff does little. I've never even heard this one before ad I've been dealing with plants for quite a while now.
Click to expand...
activated carbon is not a process, it's a substance. It is chemically active and bonds easily with airborne organic compounds - ie smelly stuff - and does not add co2 to the air - as I stated. Someone on this thread claimed filters do add co2, and I'd heard that misinformation before, so I added it as a myth. You are wrong again.

Myth five: This ties back into myth one. Of course the need for the more refined equipment also has a direct correlation to the co2 concentrations desired for the grow, and thus is linked back into how dialed in you have the other factors. The larger the average ppm you are going for (and thus the more precise your nutrient count, lumens/ft^2, ph, etc is for the particular strain you are growing) the more difficult it is to reach and maintain said levels.
Click to expand...
and I have never said anything different.

To even begin to intone that home-made contraptions of the base nature you reference as experiment worthy (which it should be apparent that it isn't) can compare to the long term control and ease of use of technology is absurd.
Click to expand...
. This would appear to be your central beef, but you only state your opinions with no back up whatsoever, whereas I have spent a couple of months to prove just the opposite of your concerns.

In only two hours you had a down swing of 50ppm which was just the start of the trend. try maintaining that day after day, week after week, month after month, and tell me technology isn't necessary.
Click to expand...
once again you are wrong as I have been continuing the use of the fermentation system for weeks and all it takes is 10 minutes a day to refill one container and I know I have sufficient co2 for my plants. Your answer also displays a lack of knowledge about what actually happens to co2 in an indoor grow. For example, just being in the room increases co2 by 25 to 50 ppm per minute - even with an expensive controller co2 concentrations vary considerably during a typical grow day.


Just another underwhelming exhibition of improperly researched and poorly put together information.
Click to expand...
just another experiment by a post graduate level research and development chemical engineer with 20 years of experience and just another poorly informed wanna be trying to take shots at me with a little scientific background.

Again, I invite you to add some value to the discussion, but so far all I see is dickishness, weak analysis, unsupported claims and continuing taunts. I get it that you wouldn't use a fermentation system for co2, but there is a segment of the growing population who likes d-I-y inexpensive solutions, and there are many growers who hold misconceptions about co2 usage, and this thread is for those people. Your "contributions" add nothing to their knowledge base. Your attitude pollutes the environment. Why are you surprised you aren't received well?

Just an update on the experiment - between house guests and an empty vegging room the experiment is on hold until mid august/September. When I start back up I'm going to be using home brewer's suggestion of safe ale yeast to see if it can save some money compared to baker's yeast.

your gotta be kiddin me, your still here.......Can you pls just stop.....you must have something better to do with you time and infinite wealth of knowledge?

Adding to the stupidity does not help. Simply accusing someone of trolling (or pretending that they actually are a troll) does not make them a troll. In fact it does nothing but give the stupid people a reason to not use their intellect.

d rat sup bro! tell me if you think this will work. i kinda copied the setup you made but im not sure if i made it proper.

all i did was make a hole at the top of the milk jug, and a hole at the bottom of the water bottle and connect irrigation hose to both

So was the myth busted? I took a smoke break during the commercials, and ended up missing the outcome. And the damn TIVO stopped working, too.

I think a good experiment would be to see if the elevated levels of CO2 actually increase your yields to the point where your time, effort and money are justified.

this is EXACTLY what i was thinking about. perhaps take clones, place them in two enviroments with the same everything except the CO2. see what the yields are. id be happy to perform this expierment for a few harvests. really put this one to rest and get a definitive answer.

WOW, so i blaze a fckin faty. FIRST one of the day, sit down at the laptop and get on RIU, find this Absolutely awesome thread.

then ithappens. the troll appears. and with him is the storm of hate.

bottom line. this fag ruined it for me. dont know who you are or what you know. dont care, you a dick and no matter if your right or wrong the way to talk to people online is ridiculous. you sound like your spitefully venting in every post. i cant even read most of your post besauce of your apparent tone.

^yea and i just typed besauce. cause im fucking HIGH. something you need to do. and if you are high, and still acting the way you act, well... id hate to be you.

anywho, desertrat, keep it up dawg. dont let obnoxious internet trolls ruin it. I miss the results, is this project still going on? where we at with this?

thanks for the support. Taking a couple of weeks off for house guests and travel - back at it in September.

ok one more question...assuming i have this dialed in and im adding 1500 ppm, what precautions should i take for my own health? i already see a difference in my plants growth and im spending alot of time in there.
Click to expand...
ive got 9 25L fermenters with about 18lbs of sugar in each running week in week out, it will just make your room smell a little, theres no health hazards unless u stick your head in the fermenter and take a deep breath, that will make you choke a little.

Just wanted to say thanks. There are newbies as myself who are indeed diy-ers, and who appreciate the information given. There is so much info out there now, it can get confusing. So instead of purchasing every "New" (or old) item available, I tend to rely on someone with more experience. So justso ya know, it's appreciated.
