so i saw a thread on here about 3 weeks or so ago... it was about wiring fans to a universal power adapter that was purchased from radioshack... I cannot find this thread, and I was wondering what is the cheapest easiest way to wire intake/exhaust fans(pc ones) so they can have variable speeds?? I went to radioshack and looked around, but didnt find anything... and I didnt really wanna ask the guy cuz i didnt know how to explain it I guess LOL all help is appreciated... thank you :leaf:

get an AC to DC adapter with multi voltage setting from 3 to 12 volts output with at least 1amp handling :)

http://www.wikihow.com/Convert-a-Computer-ATX-Power-Supply-to-a-Lab-Power-Supply

The above link is for fixed voltage

That is for a variable 12vdc source

You can also on ebay just get a pc fan control switch

Buy you a cheap dropper type ph tester,mine are under five bucks.You need to ph balance your nutes and your water if its all fucked up.Ill check my runoff ever now and then.You need to ph balance your nutes,I cant stress this enough,your plants grow better when the nutes and water are ph balanced.I use fox farm soil and nutes along with earth juice and guano and I have to ph balance everything....peace
