minitehnicus Posted January 16, 2013 Share Posted January 16, 2013 Hey all,new grower planning on building my first cab in a week or so. It will be 100*70*160cm (3.2*2.2*5.2 ft), so a surface of .7sqm (7.5 sqf) and a volume of 1.12 cubic m (39.55 cf). I will use a 250W HPS bulb and no carbon filter. I plan on growing 3-4 plants with scrog.So I found this 220v pc fan: http://www.alliedelec.com/search/productdetail.aspx?sku=70225864#tab=specs. Money is kinda tight at start now with all the other expenses so can't really afford another fan for intake. My problem is that with it's 370 cubic m/h (200cfm) it may be a bit overkill with just passive intake. What do you guys think? Buy a lower cfm fan for now that i can use later for intake with this larger one? Or i'm just worried too much and it won't really be a problem? Or just make bigger passive intake?Cheerios and happy growin! Link to comment Share on other sites More sharing options...

Dust Posted January 16, 2013 Share Posted January 16, 2013 well yeah if the passive intake is not enough just make it bigger ^^ but i think the girls should be ok, careful with the heat maybe but 1mx70 should be fine with 250wBest is to give a try and see what it says Link to comment Share on other sites More sharing options...
