Hey Guys

I guess my q's is the girls are at week 6 its about improving pot flower sites a decent subject in itself.

When lights are out do I still run a small circulation fan to keep the air moving? Night temps 18c.

Yes you keep that fan switched on as you need a constant airflow inside you grow space to avoid any rot/mold issue during flowering and it also helping the plant to improve her roots system, the wind will makes her roots go deeper and will makes her stronger

put it on a timer so it moves the air for 15 to 30 mins out of every hour u dont need it on all the time at lights out

Its best to let the fan run, a good airflow is good to mix fresh air and co2, You can decrease the humidity ( if plants getting bigger they are transpirating more) and as spinner mentioned the other benefits of a fan
