looking for a few things, please help!!!

ok so this is my first cfl grow, im 6 weeks into veg(yes i have head space for pretty big plants) and im looking for a few things for when i start to flower, which should be within the next few days. im looking for pc fans to get air moving in my grow box. where can i buy pc fans??? my plants also look like they are starting to suffer from a ph problem or maybe lack of nutes, so im looking for a check ph tester for soil and water, where can i buy this?? i know these question may seem retarded to some of you but im only 17 and this is my first grow and im not real familiar with were to by a lot of items for growing yet.

dude i picked up a lot of 2 90 mm pc fans on ebay for 10.99 free ship you can get your ph testers there as well.

thanks for the quick reply and help bro but i stil live with my mom and i dont have a credit card to order shit like this and i would not be able to have it shipped. do you know a store i could get this shit from???

OK PC fans can be purchased from Radio Shack and a PH tester can be purchased from Home Depot, Lowes, or any garden center.

make sure if you get the pc fans that they are the kind that run on 110 volts and not the ones that are 12 volts if you get the 12 volt ones you will need to get a wall adapter that you would use to say charge a cell phone and wire them up through that

how much will a pc fan and a ph tester run me, im trying to do all my homework before i go out searching for these things
