Why Temps?

I am in my 22nd day of Flowering my 2 Bubble Gum Clones, I just got those babies under a 400w HPS (previously running CFL's). What should the temps be during this point of flowering?

anywhere between 70 and 80 depending on your enviornment (temps can be higher when co2 is used) the main thing to concentrate on durring budding is the humidity, if it gets over 50 to 60 your looking a crop of mold

I've heard 70 -80F with out CO2
and 80-90 with CO2.

Alright...My humidity doesn't get too high, usually between 25-40% in L.A. right now. I am running a 400w HPS system and the temps are about 83 degrees. Should i leave my fans on even with the light is off? Is 60-68 degree's too cold for night when the HPS is off?

my temps were about that at night, but with winter here, i leave my intake fan on and its keeps it around 68. Getting better results with that than compared to last grow.

70-80 for sure..humidity 40-60%

Alright I will leave my fans on during the evening. We are in "winter" as well but the weather has been more LIKE FALL! anywho, we run the A/C at 64 most of the time, the HPS adds the addition heat to the grow box.

it's a A little cold...but I wouldn't worry if 60 is your low.
there was something about coldness and THC production.
the cooler the temp makes the plant produced THC with increased potency, but with a lower yield.
Higher temps (I think they were talking about 90 to +90F)
produced lower THC potency, but higher yield.
I never messed with it. Might be some truth to it.

k thanks for the help!
