Plants going very well!
I added Co2 with sugar yeast at about 1200 ppm when light on, and by this way I will take advantage of the upcoming temperature raise as Co2 works better with temperatures of about 29-31 degrees Celsius ,and maybe Co2 protects the plants from the heat? I am not sure but then why pro growers that using C02 have not problem with the high temperatures 29-30C when the ideal temperature for flowering is 24-26 celsius when lights on, and the quality of their product comes out as good as the others growers that not using Co2 and high temperatures?
