ppms in the 1500 range from my understanding only benefit from real hydro applications like dwc. anything over 1100 in soil is a waste of time imho. you need that contstant uptake of nutes that hydro provides to fully take advantage of that amount of co2. how could you possibly keep the ppms at that level without containing the co2 anyways? plus a cost analysis needs to be done on your experiment. again id like to reiterate good discussion here and value your opinion.
