Second day of flowering and already the temprature is at about 33 degres celcius. Any ideas what i can do to lower it???? Got a 187m3/hr fan exhaust and 2 oscilating fans and a fresh air inlet and i don't know what else to try now.

More info needed, Grow space size? Lights? What times your 12 hours on? Is that a 4" extraction fan? (tt,rvk,ruck?)

Air conditioning unit in the room outside your groom and bring the inlet in from there??

187 m³/hour may not be enough. It all depends on the ambient air temperature and lamp Wattage.
See the table at the end of this post to determine how much air you need to move: https://www.thctalk.com/cannabis-foru...ed-temperature

my groom was running 35c mate! its not ideal but your plants will be ok. try froozen bottles infront of your intake fan

aww good idea mate... i'll try that.. cheers buh..
what should the light height be for flowering using a 600w hps?
try it about 12" mate! under lower it abit day by day

as Chron says 33c isn't too bad, it may slow growth a tiny bit, but that's about it.
Sime strains such as the kush who are native to countries like pakistand and afghan are used to temps of like 35c. and they do just fine.
Don't worry about it, though an extra fan will help.

187m3 sounds like a 4" TT inline fan on its higher setting.
Light height depends on the relfector you're using or how your bulb is hung. Mine is vertically hung in aparabolic shade, I can have my plants the same height as the bulb but kept about 8 inches away from the bulb. If its horizontal, then around a ft away. Put you hand under the light and when the light feels warm but not too hot, then put it around that height.
You need a bigger ext. fan, I've got a 6" ruck fan that is over 700m3 but sounds like a harrier jet unfortunatly.
