what about in a green house would it work to an extent?
ive seen co2 enrichment supplements at a hydro shop what about those?
do they slowly release a controlled amount?
do they stop workin once the spray has dried?
my climate is extremly hot and my fence shields the wind do u think the co2 foliar sprays would benifit
