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.
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.
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)
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.
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.
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.
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.
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.
. 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.
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.
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?
