Rick,
Need your thoughts on this one-- or anyone. I read somewhere that plants
produce more oxygen in the day and then at night switch and produce more
Co2. Or it could be completely the other way around....I was thinking the
oposite on the stomates that at night when the temps are warm that the
stomates were more inclined to be open letting Co2 in perhaps to finish the
chore of the daily stored food.....In the heat of the day and if its windy
I thought the stomates were limp and not open properly...........Has there
been any theories which is best to water at night or during the
Day??.........................Brock
