temps in 60s

I’m having a bit more trouble in the winter in a “cold basement” than I’d imagined when I was drilling dryer vents for summertime venting of the heat.

So far this winter, the lights push the room up to about 74 – 76, with a 500CFM exhaust fan running. The intake air comes from under the door from the rest of the basement at about 70
.
My worry is the overnight low of around 65?

And the fact that it may get even colder…how cold can the plants get safely overnight while maintaining max budding?

Ideally no less than 65F.

They can cope with odd drop below this but a maintained drop below this point is not good.

Could be time to break out a heater.

I feel your pain bro.

I have 2 different exhaust fans depending on the season that i use. lol

Luckily i grow in a bedroom so as long as my house is warm the grow stays warm.
