Temps 15c at night, how will this affect the grow?

[willc]

My temps are normally around 15c at night, sometimes as low as 12c, theres nothing I can do about it as I need to have the extractor running to keep the negative pressure and the smell going outside. Ive put a heater in there but doesn't have much affect as the heat just gets sucked straight out.

What negative affects will this have on the grow? They're at a nice 27c with lights on

If the plants are pure sativa that will be a big help in survival. The plants won't die - however growing in extremes creates stress for the plant which will slow everything down...

Good luck

Run the lights at night, that'll raise the temp a few degrees.

Anything under 10c and the plant will stop growing. So you should be fine.

I see. How about slowing the fan down? Constant extraction really cools the place down when lights are out
