In auto flower indoor, Early veg, is better have 18ºC/24ºC, or stai around 23°C during all the day. I have an Inkbird that I can set on 23, that is cool when is light off, it warm it up. But with light off it’s drop down temperature to 23.
Aabacus day and night difference should not be higher by book than 7-8 cel.
Ussually everyone speaks about day time temperatures
I noticed in veg higher temps are good, later makes fluffy buds.
So on week 2-3 of flowet i start to drop them from mentioned below
