I've come here to learn and discus, not hear about your opinion on CO2 and plant roots. If you are 100% sure about what you say, also proove me on the other thread why plz (don't use outdated books or articles, science has come a long way...)

Don't really care about your opinion, and my post count is utterly irrelevant to the topic at hand.
I'm offended that you would even suggest that I stop thinking or learning. Right now I'm taking a shit and STILL reading (other than this thread). Every single day I'm reading and learning new things; how dare you imply otherwise.
I base my statements on simple plant biology. Leaves use CO2, roots use O2. Argue all you want with/for those CO2 tabs, the simple fact is that roots don't use CO2 (or, at least enough to actually make a difference, if you really want to split hairs).
Furthermore, you might want to read up on posts in that thread
other than your own. Quote:

Cannabis isn't an aquarium plant, it won't respond to CO2 in the same way that other plants do. I don't understand how you can be getting a bigger yield and better buds by dissolving CO2 into your water... the roots will literally choke and be burned. Plus, roots are never exposed to the light, and the only time plants use CO2 is in a photosynthetic reaction, involving light.
I would advise against this method, sorry dude, it's just not right for this type of a plant. But can you post some pics of your plants and yield? I'm interesting in seeing them  |
"Should I add C02 to my hydroponic reservoir? I noticed an aquarium product called Nutrafin CO2 Natural Plant System. It adds CO2 to the water. Would it help the plants in my hydroponic drip system, which has a small reservoir?
Steve,
Internet
Adding CO2 to the water will not help the roots and in fact will hurt them. Plants use CO2 when they photosynthesize, the process which results in the production of sugar. Photosynthesis occurs only in areas of the plant that receive light and contain chlorophyll, the source of plants' green color. It is absorbed through pores called stomata. Roots have no chlorophyll and don't ordinarily come in contact with light so they have no use for CO2. Plants use the sugars they have manufactured as a source of fuel. Their metabolism is similar to the method used by animals. Sugars, which are hydrocarbons, are chemically "burned" in a controlled reaction that occurs when they are combined with oxygen. Energy is released and the waste product CO2 is created. Both CO2 and oxygen dissolve in water. When water is saturated with CO2 it cannot absorb oxygen so the roots have no source of the element oxygen, which is needed for their metabolism. This weakens the roots and promotes the growth of anaerobic bacteria, which thrive in oxygen-free environments and attack roots. When water in a reservoir is circulated, it releases the dissolved CO2 to the air and dissolves oxygen. That's why circulating water in a reservoir using a pump is beneficial to roots: It removes the CO2 and supplies the water with oxygen. Nutrafin CO2 Natural Plant System Tablets spur the growth of photosynthetic underwater plants."
Now if you want to discuss this, not only should you make your own thread, but you should also reserve the smartass comments for when you're
not wrong. 
Oh, and don't use advertisements as proof either, you're better off just making things up yourself. Bring some actual, scientific proof and we'll talk.
