I feel that based on the data, co2 in the root zone is clearly shown to be at least somewhat beneficial to the plant.

Generally hempies are operated without microbes. You don’t need them. Hempies are not soil grows, though they could be adapted, a little reservoir in a bucket with a hole isn’t rocket science.
Maybe from the addition of CO2 in the atmosphere, sure.
CO2 is really only a concern if you’re already reaching a plateau in yield, or operating a sealed environment. Again, and trust me on this, get the fundamentals of the hempy down first. It’s very easy from the lack of moving parts but it does take a few cycles to properly learn it’s intricacies and do it right every time. Biggest thing is the media pH at the root zone. Which, again, the carbonic acid will drive downward very inconsistently. In a 5 gallon bucket of media, fully saturated, there’s about 1.5-2 total gallons of water depending on media. It is very easy to throw off the pH of 2 gallons of water and soilless media has limited/zero buffering capacity. You want to avoid this, there is no large reservoir like hydroponics. Glossing over a JSTOR abstract isn’t the same as experience.
Do whatcha want, but best case scenario nothing happens, worst case you kill plants and make a big mess. You’ll have plenty of awful tasting sugar “wine” to drink from your fermentation carboy, though. I used to drink it when I was young/stupid and couldn’t legally buy or afford booze. 1 gallon Gatorade bottle (nice thick walls), a check valve, and airline tubing is all you’d need.

Haha, yeah thats what they tell me…i usually stick to drinking beer though.

IMO hempys are perfect for organic with micro. The porosity of perlite is perfect for colonization.
Hempys are also very easy to use with synths or lucas formula etc…

If you wanna do things the hard way for no tangible benefit, knock yourself out. I don’t know everything, but I do know hempies.
Most root microbes exhale CO2…adding it will garner zero benefit. You’re gonna have a better time running sterile.

The Hempy media is also reusable…
