Hey, it's been gettin really hazy the past week er 2 in western canada, all those smokers in BC . but seriously is all the co2 in the air from the forest fires good for the plants? or is it canceled out by the bad toxins?
smoke isn't usually a good thing for plant health
how much smoke before problems show? don't know the exact answer
the co2 should disperse very quickly into the atmosphere, so probably no benefit
