... although a htg mat might be beneficial, IMO he needs to control his ambient temps. He is growing in an unheated basement during winter. His light on temps were 14 deg C. That is why he opened his lights. What are the tent temps at lights out? IMHO his environment is not conducive to good growingGet a heated grow mat. You want roots warm, plant not fried by light.
Your plants need 18/6 because they are vegging. You need to address this now before you get into a 12/12 cycle (worse)Ok, then i'll leave em open all the time. As far as temperatures go, when the lights are out i am around 20 - 22, when lamp is on i reach about 27. My humidity is 50 - 70% when dark, 55ish when lights is on. The temp you see on the meter is when i opened the tent after a few minutes to check. Anyhow, because again i'm totally confused, since my light is that strong atm can i leave my seedlings without any light or i must provide something else? Note that the lamp is nowhere near the seedlings. As i said before i am trying my best to give them the best climate i can.

Hey Rab, thanks a lot for the suggestions!
The truth is that i had the rvk fan on top of the tent but because as i mentioned, this rvk fan is too strong it's also producing a lot of noise even when the dimmer is applied. And because i share the basement with some relatives they told me about the noise so i changed the position. From the flow perspective i agree that is way better that is out.
Also, for the duct, ye i think it's a bit too big for this distance, but i also think i might need it to be a bit longer since it's connected to the cool tube and the lights in some weeks will have to go lower. Atm it's inactive anyway since i placed the led grow panel in order to help the seedlings and not fry them to death!
