I don't have a tent but if you growing in a tent just keep it at recommended RH and temp for veg/flowering stage fan on or off as long as those are in range

Can i wait till week 4 or 5 before i have to turn on my fans?
Or do i need to do it right after germination
The girls like to dance....not rock and roll but gentle movement 24/7. My 5x5 I've 2 small on top blowing down on low and 2 osculating 1 over he top and 1 mid height over the pots on the low setting as well on 5 large plants.

I keep my fans on 24/7. I have one over the canopy and one under the canopy. Both are on “high” (they’re small fans so high isn’t that powerful), but I did start off on low and pointed away from the plants for the first 2-3 weeks.

Moving air helps prevent mold and mildew.
