Hey peepz! Howz everyone doingz? I was wondering if anyone knew about using Co2 during flowering? I've heard that using Co2 during the last 2 weeks of flowering is not good for the da ladiez. Is this true? Any advice would be greatly appreciated! happy growing everyone!
 
ive never had any problems... i run my co2 thru out the whole flower think of it this way we breathe oxygen if u cut off our air supply we would die, so takingthat as an example plants breathe co2 y deprive them of what they crave
 
Bump.

Ironically enough, I was going to start a thread to ask this question yesterday, but fate has led me to this one.

So, could any experienced and successful growers give an answer as to their thoughts, with an explanation?

I run CO2 at 1500PPMs and if I could get by for two weeks without doing it, I certainly would.
 
CO2 does not have to be at a constant ppm, it just needs to be at a ppm adequte to the needs that are related to temp, lighting intensity, nutrients, humidity and water supplied. Basically the higher the transpiration the higher the ppm needs. Therefore it depends on many things. Just injecting more CO2 doesn't provide any benefits unless the other parameters are in line. ie lower the humidity and raise evertthing else and CO2 will increase growth, other wise your just pumping in CO2 for nothing.

I even dry and cure in CO2. Keeps the plants growing after harvest. Eliminates the need for flushing. They continue to use up nutrients stored up in their tissue s and will draw from everthing else before they draw on the nutrients in their sex glands. Their desire to reproduce is amazing. Definitely does not decrease potency or ruin the taste. With use of CO2 and nutrients until harvest the plants are harvested grren and remain green through drying and curing. I actually use CO2 to dispel all air from the drying and curing areas. I simpy use a dehumidifier in the drying closet to reduce moisture. The door is taped during drying. The curing is done in air tight platic containers with a CO2 inlet and out let. CO2 is injected woth the outlet on top left open. After a few seconds the outlet is closed and the CO2 inlet is closed. The cureing compartments are opened every three days and moisture laden air escapes. The CO2 procedure is repeated. No off tastes, no green chlorophyll tastes, no chemical after tastes or bite.
 
All CO2 does is prolong harvest if used in the later stages of flowering. Thats why it is wiser to use in mid flowering.

That's a marijuana comic book. It is a lot like Sesame Street. A primary where any body but children know everything that is about to be presented even before it is presented. Dejavu to the max.

You run CO2 any time the paramerters are high enough (temp. lighting intensity nutrient/water availability) that CO2 is beneficial or in short supply naturally. Basically if no fan is i used then use CO2 at about 75 F or warmer if a strong fan is available use then CO2 is usually not need as a supllement at temps below 80 F. CO2 is like any of the other plant needs. If you do not provide for a plants needs as far as growth they just survive and little more.
 
I know this is an old thread...so forgive me..
I have found that in the last 2-3 weeks of flower, CO2 with PPm's above 1000 can cause foxtailing in some strains..For instance my Bubble Chunk(tripple berryXsuperchunk), will severely foxtail, and XJ-13 will have some minor foxtailing if I dont turn it down..It seems that light feeders(which both of the above are) have the most problems with this. My other strains seem to do fine(a little Foxtailing with Pre-98 bubba, but that might be a heat issue..first run with this cut).
 
heard? co2 with all other factors in line will increase the metabolisem in all stages of plant growth. i run it all the way to the end these days just lowering the ppms the last couple weeks to about 1100-1200 from 1500 from the beginning of flowering, (i worry about tasting carbon but never have). i feel from trial and error my shit will even finish sooner with it to the end. but wtf do i know.
 
I added c02 mid flower when I first got it. I increased my production by almost 20%. It definitely does help mid-late flower. I also agree that without the other environmental factors in place it doesn't do as much as it could.
My next flower, having c02 from the start, showed great improvement and it may be most beneficial during early flower but it still helps late flower.
 
Plant Photosynthesis = Light + Water + C02

Ask yourself, what happens when you deprive a plant of Light or Water, in any condition?

Then ask yourself what happens when you deprive the plant of C02.

Hate to reign on feelings and hunches, but running C02 to the end IMO is a key part of the photosynthesis equation. 25% more Yield.

just so you know, this thread died 7 years ago.

and running CO2 to the end hinders the ripening process
