using Co2 in res! crazy results!

[StinkySnowDank]

You DONT want CO2 in your res or in your root zone. CO2 is a is a by-product of plant metabolism that is released by the roots in your nutrient solution. You're in effect "polluting" your nutrient solution. A good hydro system works well because of highly dissolved oxygen in the water....which is dissipating these gases out of the nutrient solution in your res.

In short: CO2 in root zone = Counterproductive

ya i would say i still having good results with o2 in my 4x4 tray
the roots love them bubbles of o2 keeps them breathing.

 

[MarquisBlack]

Like ShroomDr said, too much CO2 dissolved in the rez will dramatically lower pH.

 

[norcal woodsman]

loco81 wut up bro where you at how is shit going bro...
hope all is well you know we live and learn bro... so hope to see your progress....

I would hope so, CO2 in the root zone can be toxic. Plants absorb CO2 through their leaves, they absorb O2 through their root system.

Plants absorb O2 through the leaves. Photosynthesis, respiration and photorespiration are all processes that take place in the leaves.

Doc's simple solutions Liquid Carbon bloom 16 oz.

Plants don't waste time converting nutrients to usable energy with Doc's Liquid Carbon. Doc's Liquid Carbon Bloom and Grow deliver energy right to plant roots while they reduce nutrients to base elements. Bloom formula promotes rapid, big blooms, and both formulas help plants resist drought and also increase success rates with cuttings. One gallon of Bloom or Grow will super-charge over 500 gallons of finished fertilizer mix!


I have tried this product with mixed results. It is pretty neat stuff though.

Yep, with O2 being the byproduct, or end result (that and a bit of moisture.) Why would we need to aerate soil, add bubblers to reservoirs, etc., if the roots did not do the O2 uptake thing for the plant?

Plants also take in O2 through pores in the leaves (stoma) for respirational purposes. O2 is the product of photosynthesis (CO2 + H2O + light -> O2 + H6C1206), which can only aspire while light shines on the (green) leaf, while respiration (H6C1206 + O2 -> CO2 + H2O + Energy) happens all the time.

Now fill in the numbers that balance those equations. Everything becomes toxic at certain levels and pressures (O2 can kill you fast at the right pressure, just as too much CO2 becomes toxic), so there is always going to be a blend of the gasses to keep things safe. Run the numbers top and bottom and see how the ppm varies for each.

so what is the optimum res temp?

 

[Blunt_69]

Can sombody please explain why you would inject C02 into a rez??? The thread i read through CC was amaturish at best(yes i read the whole thing), in a non controlled enviroment..

Somebody please elighten this grower as to what in the fuck is C02 gonna achieve to the root zone??? As already stated a thousand times C02 is absorbed by leaves, not roots.

All you gotta do to avoid root zone problems is keep your temps in range. This is done with a chiller or some method that involves cooling the water.. There is only one way to grow properly in water.

I am having trouble with these pointless threads that are spreading garbage.
Im telling ya. BIG buds are big because of proper growing procedures, not some magic voodoo.....or whimed experiment..

fuck i just bumped this shit didnt I?. No offence their loco, want big buds??ignore stupid nonsense.

 

[stink.whistler]

I guess because they want to jack up their pH, or maybe waste money?

You said that O2 is the end result/by product of photosynthesis, photorespiration and respiration. I only tried to explain why that is not a fact, since O2 is never the end result/by product of respiration.

which you could easily correct with a bicarbonate buffer

 

[inefectualize]

instead of just spewing some canned facts that i learned in high school level biology i googled "co2 uptake in roots" if you would like some more information i have listed the links....very very interesting stuff....i think that if you are growing in soil (especially organic with lots of micro organisms constantly spewing co2) any more co2 to the root zone would be wasted. I think that in a hydroponic set-up this could be very different. I would not be surprised if CO2 in a rez is nowhere near what it would be in a fluffy bio-active soil. Has anyone here ever grown planted aquaria??? i think you will get what im saying.....
