Temperature

I have set up my grow room in my unfinished basement, and i live in the northern part of the u.s. so it can get kinda cold around this time of year. I was wondering if my grow room is only about 65-68 degrees will it keep my seeds from germinating??

is that the temp w/ the light on or off?

i use a lot of flouros, so that is with them on

i try to get the temp w/ light on around 72-75. then when off no lower than 60...cooler than that when off will stunt growth. keep that in mind i guess. you know what the temp is when the lights are off?

if i had to guess when the lights are off i would say it is probably around, 62-65, but i have them on 24/7 until they are ready for sexing
