From a 20/4 cycle to 24/0

[TedeBoy]

I've been running my 3 week old White Widow autoflowers at 20/4.
The exhaust fan is on a thermostat. Circulation fans on 24/0.
During lights out humidity peaks up to 80 at times whereas during lights on in the 50 to 60 range.
Not a concern now but as they get into flower I'd like to move the light schedule to 24/0 to avoid these spikes.
Will that mess with them? Should I gradually switch them like say 1/2 hr per day until 24/0 is achieved?

On edit...I will try leaving the exhaust fan on 24/0 and adjusting the fan speed for control of temp. However the ambient air temp the tent draws from is variable so it may be a challenge.

i thought autos were supposed to be 18/6 or 20/4?

It varies.
Growers have reported success with them at 24/0 also.
I think I'll experiment with leaving the exhaust fan on 24/0 and adjusting the speed controller as needed for temp control.

Or one of these?

Anything 18/6 or greater is fine for autos, there's arguments on whether 24/0 is ok but really it's a matter or preference and opinion. Switching the light schedule shouldn't matter since most autos flower regardless of light cycle.

Is a dehumidifier out of the question?

I'll explore this also thanks. I'll need a small one as my space is 3x3.

I keep mine outside the tent, and it works great, Until winter, then I put it away and break out the Humidifier

I'm gonna get a night/day thermostat and essentially have the fan on constantly during lights off.
My ambient temp outside the tent during lights off rarely gets below 67F and I think the constant air circulation will help.
After that a dehumidifier most likely if this doesn't work.

I'm running 24/0 for exactly this reason. No issues so far.
