total beginner here, i hav a stealth its 50cm (w) x 50cm (d) x 150cm (h) im plannin on using 2 silent 40mm pc fans for intake and outtake, how would i connect my ducting and carbon filters to these??

many thanks in advance for any replys!!

lol fair enuf, ws just wonderin cause the fan is completely flat, but i supose lots of duct tape wud work!! thanks. my grow box is 50x50x150 could anyone point me in the direction of where i get info on how many lumens i wud need for this?? alkl very confusing. using CFLS, i know most you guys hate them but i cant afford a hps or mh. well i could afford a 150watt hps bt can seem 2 find them for shipping into the uk/ireland!!

I used a 4 inch duct clamp to attach ducting onto one of my computer fans. It worked a lot better than duct tape and a lot cleaner looking

got a pic? id like to see that

You need a MINIMUM of 2500 lumens per square feet, better still is 3000. I found 85 watt cfls, 4200 lumens, full spectrum 6500K, at www.1000bulbs.com.

No problem here's some pics from my terrible camera. The ducting and computer fan are attached to a homemade cool tube for my 70 watt HPS. It was a little hard to get a nice pic cause of how cramped it is in my veg box

sweet deal thanks for the pics man

thanks 4 the advice lads n ladies!! wil keep ya postd!!
