I built a small grow box but completely forgot about venting. I was considering just using a desk fan and leaving a door open but that'd probably screw the flowering phase, in a couple months. From reading and replies, I gather putting in a computer fan is my best bet. My question lies in powering the sucker. I have a bunch of power transformers I've gathered over the years, but all the fan advertisements say 3 or 4 pin. I don't know if I could wire one up right. Is there an easy way? Any suggestions?
get an old adapter.. like an cell phone charger or anything else that converts it to 12v. then cut off the end, attach pos to pos, neg to neg or use the search button.... http://forum.grasscity.com/showthread.php?t=106070
That's exactly what I did. On another forum a guy explained I needed to use the red and black wires from a computer fan plug and I spliced them to an old 11v cell charger I had. Works like a charm.
and also you dont need to drill holes to install your fan, just use the high temp melting hot glue then your set... thats what i use on my stealth grow..
I was wondering how i was going to sort this out. Thats a real help... I'm awful at wiring though. So my biggest worry is how to stop it from setting ablaze to my entire crop.
