I have never seen an increase in yield with CO2 at the level of the rhisosphere. So, you think the dissolved CO2 will increase root mass?

Great questions Glenn.

Dissolved CO2 foliar spray has never been thought through to accelerating plant growth. Dr. Julius at St Cloud State is doing great work for us articulating the plant science on why it works so well.

I think that dissolved Oxygen would for sure. If the principal for dissolved CO2 works for foliage like we have seen evident in this VERY educational AMA (thanks @sam.kanes for that!), then I could assume that it would be effective in the root zone. Itā€™s something I would like to explore on a professional level for sure.

Edit - then I could assume that dissolved O2 applied to the root zone would be effective.

Certainly worth exploration.

This HAS been VERY educational , hasnā€™t it?

Other than noticeable increase in yields through foliar application of CO2, what are the other most remarkable benefits over traditional application methods i.e. cost, consistency, efficiency, pest management etcā€¦?

Can this application be used with any standard misting system or is special assembly needed?

Thanks,

Hi John, thanks for doing this AMA!

What are the main benefits of using CO2 saturated water? Is dissolving CO2 in water more effective than simply increasing atmospheric CO2? And if so, do you have a theory why that is?

I didnā€™t get a chance to ask about plant respiration, which happens when CO2 levels in the environment rise. As CO2 levels rise (think climate change / rising temps), plants release less CO2 and hold onto it. (Iā€™ll PM Sam and report back)

If temps are rising and plants are holding onto more CO2 naturally, how does this affect their process?

Hereā€™s a Smithsonian article on the subject of plant respiration: Way Plants Trap CO2

Hey @sam.kanes and GNET members at large, I just want to thank everyone who participated in this lively and informative AMA! I know I took a lot away from it.

Thanks for the great AMA. Iā€™ll be in contact when budgets get laid out for next year.

On the dissolved oxygen front, we have a product we have been using for DO infusion for the last three years. Our site is about to get a much needed facelift, but check out o2toob.com. I also have pics of my setup and install on my instagram pageā€¦

Message me for more info. We have installed in countless growsā€¦both small and commercial. It scales between the entire range of flow rates and we have complete automation. I can speak personally to its efficacyā€¦from perspectives of both yield and risk mitigation. :muscle:

Thx Nick for setting up. Our press release from yesterday. Will have 2-3 more this summer re cannabis.

Best Sam.

Nick and Hunter ā€“ new from us this AM in cannabis PR attached.

We had no idea we could get 75% more THC from our dissolved CO2 grown buds versus no CO2 gassing buds.

SGS Canada Inc. did the lab analysis.

Best Sam.

We are finally gearing up for dissolved CO2 irrigation installations in the US. Would like to chat. 416-315-7477. Thx Sam

Good Stuff!

I work with and build Carbon Fertilizer formulas bio technologies that are nano particles geared towards your system. I believe nano tech is the future.

Do you supply nutrients ?
I have research over the last couple years of myself and ag biotech scientist dialing in the micron size four formulas to be able to fit and also looking to micronize as much carbon as possible . Love to learn more

Just what I was thinking as reading

absolutely not.

  1. there is a saturation limit of dissolving CO2 into irrigation water of about 1700 PPM at room temp.
  2. when lightly Foliar Sprayed, cannabis plant leaves consume all the CO2 they need in 90 seconds for their next mini-grow cycle
  3. the leaves will be dry before the next 30 minute Spray cycle starts
  4. any CO2 not used or missed on the plant canopy will have evaporated back into water and CO2 gas

I am just going to play with this. Do you have some reference papers.
