Taking the example of PNW yew in bowyery, the yew that is best for bows grows slowly, in the shaded understory of foothills, as I understand it. If you try to use coddled yew, grown with plenty of everything it needs, the grain isn't as dense as it needs to be.
It might be a slightly different phenomenon than what we see with growing food in inert or depleted media (lifeless soil, most hydroponics and sterile media growing), but if the plants are growing so fast that other processes responsible for their health and nutrient density can't keep up, we might be looking at a similar situation.
So what if, as with the coddled yew growing in one season what would take the shade-grown yew several, the fact that these plants are growing so much more in a single light cycle between rest periods compromises their nutritional value or gene expression?
It has often been speculated that hothouse-grown produce was nutrient deficient simply because the media being used were sterile. But what if there's more to it than that?
But to address the idea, people have burned candles and other fuel-burning appliances to afford CO2 and heat for their greenhouses for centuries, I would imagine. The idea is sound. My opinion on its application, though, is that it's a great solution for CO2 starvation in the greenhouse, but I would stick towards the high-end of normal outdoor C02 levels.
But good luck, please don't suffocate yourself or others, and keep us posted.

This whole line of inquiry came up because I met a couple people who design heat and CO2 enhancement systems for commercial growers and they're interested in biochar. So next I started thinking about RMH applications as well.
