Yes, need to have air circulating inside the tent because water vapors will get trapped under the leaves otherwise. Good luck

To add to my "yuppp" the fan blowing air directly on your plants will strengthen branches and decrease risks of mold and fungus. I'd highly recommend it.

As long as the airflow is enough to make your plants tremble, you should be fine. Can't hurt to get an oscillating clip-on fan though.

Low humidity issue
Tents 20'' × 30''. Using a vivosun 6'' inline fan to exhaust with passive intake to create negative pressure. I have a good humidifier but even on full the rh doesnt go above 40%. Not unless the room the tent vents into becomes super humid as well.

Smell at 2.5 weeks?
Is it normal for a Quick One to smell strongly at 2.5 weeks? I only have one plant, and moved it out of my bedroom to the spare room where there are fewer clothes. My partner could smell it downstairs and the plant only just got its 5 tipped leaves.

Temp fluctuates
With the Heater I have(analog setting) fluctuates (needs to drop 6 degrees) before kicking on. So my Lights off temp fluctuates from 67F lowest(about 5min) to peak 74F(<5min) maintaining an average of 70F lights off. Is this too much of a swing?

Cooling whilst using humidifier outside a small grow tent
I have a small 90x90x60cm grow tent with a VIPARSPECTRA 300W LED. Heat levels are crazy and running a small humidifier with ice blocks inside the tent along side extraction isn’t cutting it. Could I buy a bigger humidifier, keep it outside the tent duct it in to keep it cool?

Overheat in tent? Measuring Correctly?
HID lights on seedlings day 2 (25 cm dist.) I was alarmed by temperatures rising since yesterday to 35 despite exhaust & small fan inside tent. Tent doesn’t feel overly hot. moving sensor to above light it reads at a good 26-27. What’s the best way to understand tent temperature?

Humidity vs airflow? 8 day seedling.
Humidity VS airflow for 8 day old seedling, which is more important? My seedling is in a propagator with 60-65% humidity. Outside the propagator is at around 40%. I'm waiting on my humidifier. I'm going to raise it with a wet towel and containers of water. Should she be in tent?

Risk of bud rot with these conditions?
My tent keeps bouncing between 55-65% throughout the day during mid-late flower stage. Staying between 24-26 C. I have two fans moving air in the tent and the plants are we defoliated. An in-line fan is pulling air out. How much at risk am I for bud rot? Thanks!

High humidity
Hello. Even with a dehumidifier and a 24-hour extractor, the humidity is still above 70% and one of the plants is almost in the flowering period. Can I add expanded clay on top of the vase to see if it lowers the humidity or putting more perlite will solve this? Thanks.
