Fluctuating temps! Is this a killer?

Hey y'all...

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 down to about 55-degrees. I probably need to warm it up a bit.

Here's my question: How stressful will it be to the plant if the plant has continuous hot/cold period throughout the night while the heat cycles? For example, it'll get down to like 58-60, then the heat would kick on and bring it back up tol like 63-68. This might happen a couple times a night. A slow transition of maybe 5 degrees back and forth? I can't keep it constant because the basement cools off much faster than the thermostat location. So, when the thermostat cut off temp is reached, and the heat kicks on, the basement temp is already 5-degrees below the cutoff temp. And the vent in the basement is massive so it heats up faster than the upstairs.... it's a fucked up heating/furnace system I will admit....

Peace,

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.

I also forgot to mention, but in my case I dont want the flowers to exceed 2 ft in height and the colder night time temps actually help my flowers remain small but bushy. In a way its kind of a plus for me.

Temps even when pushed to the plants extremes don't affect yield or quality. They do slow down the growth of the plant but people on here have had successful grows with temps up too 115 and and low as 55 degrees.
