shouldn't be too bad. I'm pullin the absolute extreme on temps and my flowers are doin just fine. night time temps are about 60-65 and during lights on my temp gets up to like 90-95. besides a little purple in the stems there all doin just fine. as long as the temps dont get down into the low 50's and lower I think it's fine. Its not optimal but yet again I am using miracle grow soil. I wouldn't be too worried bout it unless you notice that they slow down growth dramatically. Just keep and eye on em and if you are worried then try using a space heater on the intake side of your fan to up the night temps a bit. :thumbsup:

Just think of those occasional cold summer nights where the temp gets down to the 50's(nature). In the end its a weed and it ain't that bad.

So this room is in a basement next to an exterior wall (one side of the basement is aboveground and this is on that side). This building was built in the 1930s and has SHIT insulation! If I set my thermostat above 70-degrees it would stay on for probably hours. Anyway, the basement does have a heat vent so I can pump heat down there at night... right now we don't run the heat at night to save money. Anyway, at night down in the basement without heat it probably gets Rating: 5
