Believe in ones self Posted March 7 Share Posted March 7 Hi all just wondering if someone can help me out….. building a new room and when the walls finally go up and it’s enclosed I’d be left with a 3.3x2.5m2 room, any suggestions on what size fans are best suited for this space, I’d personally thought 8” in & 10” out but someone might suggest otherwise? thanks 1 Link to comment Share on other sites More sharing options...
BilgePump Posted March 7 Share Posted March 7 I've no experience with venting such a large area but.... And its a good but ... What are you going to be running light-wise? Hid will require a bit more oomph than a led room and might dictate where/how you rig yer fans (a fair few of us led growers flip out tents so we pull air in the top and blow exhaust out of the bottom to maximise heat efficiency) 1 Link to comment Share on other sites More sharing options...

Believe in ones self Posted March 7 Author Share Posted March 7 So fresh air (intake) high level and stale air (outtake) low level? Link to comment Share on other sites More sharing options...

They run so cool that in winter people do that to conserve heat. No idea on fan recommendations, but bigger is generally better. Link to comment Share on other sites More sharing options...
Devon Cream Posted March 7 Share Posted March 7 Iv roughly the same space as that in a barn south facing . Running a 8” 1300m3 Systemair outtake and a 900m3 Systemair intake running Lumatek and think grow led and the temps don’t go over 29c and that was the hot summer we had the summer before last . Depends where your area is gonna be obviously attics and south facing areas will be warmer. 1 Link to comment Share on other sites More sharing options...

Would that matter if drawing fresh air in from within a bedroom below or is it only done if fresh air is drawn in from the outside with cold winter air coming in?

I take it u run a 6” intake bring less m3? cheers for the info, I guess they don’t run at full capacity anyway on a normal day -day? Was going to invest in one of those G.A.S controllers which regulate both in and out air, from what I’ve read they seem to be a good investment? p.s cheers for the reply both of u Link to comment Share on other sites More sharing options...

We do it even when pulling warm indoor air into the tent, cold air straight from outside isn't really viable in a led room, its just too cold most of the year save for a fortnight in August.

Nice one bud for that info, I’d of always done it vice versa, being fresh low and stale high, do u have fresh as high up as u can with using led?

Yes you can plug heater etc into them I run a humidifier in early veg but that is run off a humid stat that was already in the room before I upgraded the room.
