Indoor Too cold during the dark?

[chickenhead420]

My lights are on a 19/5 schedule, 2000w. When the lights are on, fan, etc, the temps are about 76-78 steady. When they go out, I still keep the extraction fan going though so no smell leaks out. This drops the temps down to about 66 an hour or so after the lights go out, and for the next 4 hours until they come back on. Is this too cold? I don't want to run a heater. I could spend $60+ on a fan/temp controller that would slow down my exhaust fans based on temps, or go to 24/7 lights, or just leave it and quit worrying. lol.

First grow, went away for 2 days and came back to the best growth since I started. Since I wasn't there messing with this or that or micro watering or anything. lol, so I know sometimes less is more and less messing around the better.

Mine runs like that with temps. I haven't had any issues yet. My tent gets about 75 hot down to 63-65 without light

No problem having lower temps when lights are off.It's the same thing in nature when it cools off at night.

Your temp range is perfect for growing. I would not worry any more.

Mine runs the exact same and I get phenomenal growth... and the best thing is ALL your plants will purple up at the end due to cooler "nights"

It's fades in drying and curing but is awesome during flushing
