Small grower question

ok, then wrap it up with electrical tape and i shouldnt have any heat issues?

nop ur safe with 12v. :)

I tried using an 18v and the fans didnt even move, just clicked a little, would a 12v even work at all...

yeah wrap it up with insulating tape but those fans have 3 wires the yellow wire is for revs per minute (rpm) which is used inside the pc to control the fan speeds so if you are gonna wire this baby up to a 12v dc adapter pnly use the red and black wires
on the adapter you will see that the 2 wires are black but one of them will have markings on it which will be lil white lines this is the wire you will wire to the red wire on the fans and then you will be ok
let us know how it goes m8
hope this helps cheers :)

How long should the fans remain on the plants i just went out and got a fan at the local store for 10 bucks, just wonderting on the time though and about how long till i start seeing decent results?

all the fan does is strengthen the stem of the plant and help airflow around ya room and plants i have mine on a timer with my lights so they come on automatically they are a must really with the stem beeing stregthend this means it will help ya plant support the wieght of the bud once it starts flowering
cheers hope this helps

If it didnt work with a 18v, what would make it work with a 12v, i just dont wanna waste another DC adapter, i got all the wiring down, its kinda common sense to me, i was thinking i only need 2 of these fans, one for intake and one for exhaust., if i did use 2, would i only need one adapter?

you could wire all 3 to it if ya really wanted m8 i have 3 fans running on my adapter ill post a pic, i made a fan tube with 2 fans bolted on top of each other and attached to one end of a speaker porthole so i can direct the air better
tell me what ya think

i did it and it would only power one, and very lightly..

im not too sure then unless ya can get a dc adapter that has difrent voltage settings on it that would maybe work
if not i would get some difrent fans from a pc shop m8
80mm fans are quite cheap
cheers hope this helps my freind
