What you do is get a 12v DC transformer (like the cell phone ones listed or go to radio shack and get one.) then connect the 12v transformer to the fan controller and then just hook the fan right up to it.



My controller will control 120 4" fan per circuit so I could in theory control 480 fans with this 1 controller. And since this fan control is intended for the computer the computer fan plug directly into the controller. To connect more then 1 fan per circuit you have to just splice them into 1 cable and run it to the controller circuit.



For me this works awesome because I can control the speed of the fans per the 4 different circuits and have tons of room to grow so to speak. I also like the fact that they are all running on 12v not 120v which is WAY safer around the 20gallons of water in my hydro set up. they are also cheaper to run, cheaper to buy and quieter then 120v fan IMO.



Here is a photo of mine in action… I’ll try to get a shot of the inside for ya later today.
I decided to bring this post up again, because there may be many out there that are looking for an inexpensive and easy way to build and cool a clone veg cab, or in my case, plastic tub set-up.

I am in the process of building some clone veg. chambers (and I'm sure a flower chamber or two along the way ). I read this thread a week ago and went shopping. Being a natural born cheap ass, Price was HUGE to me, and I don't have a pile of odds and ends around to just slap one together with. Here's what I did thanks to this post.

2 - 18 gal. plastic tubs - $3.98 ea. w/covers 16"x24"x16"
6 - New computer fans - $3.10 ea. 3"x3", 32CFM, 2700RPM w/connectors
1 - Fan Controller - $9.94 ea. Nexus Brand, 4 speed controls & alarm
1 - 12V adapter - $5.39 ea.
Based on 2 fans per unit, and 2 units total. the total cost is - $35.66 0r $17.83 each. With the chambers, fans, fan controller, and 12V adapter.

I have recently built some 35W, 2050 lumens light units @ $5.07 ea.(that's cheap considering I've seen less powerful CFLs (without sockets and cords) in the dollar store for $9.50) Then I purchased a 2-pack of 6 socket ea., power strips for $4.30. So now if we add 4 lights per unit and the power strips we total $80.52, Or $40.26 per unit.

That's all tax and shipping included, For perfectly clean brand new light sealed units that are portable, and capable of holding up to 12 clones each (comfortably). That would be only 140W of power for lights, and 12V of fan power (my favorite part as being the natural born cheap ass that I am ) And they're are tall enough to allow a plant to grow quite a bit. (and a larger tub can always be used if you like)

I will add mylar throughout top, sides, and bottom. (granted I already have the mylar), but there are other options for reflection if you don't. Frankly, this could be as easy as using the matte side of aluminum foil.

Now I'm a light monger, and will be adding much more light to these units, as well as fans as needed. But I very often see people posting that are veg'ing clones with CFLs that are about this wattage and lumens range.

Even at this, the light units are only $5.07, and fan units $3.10 each (and I'll have the empty sockets in the power strips, and the fan controller will be able to run the extra fans). The assembly of both units will take all of about 45 mins. And no swearing.

Thanks StOney, for the fan controller Idea. I didn't even know they existed until I read this thread. It was what actually motivated me to finally start shopping (that and the info I've gathered from so many excellent posts).

I used to just grow from seed, But at last, I'll be enjoying the beautiful ladies I have for years to come.

If anyone is interested, PM me and I will tell you where I purchased these parts. "I am not a part of any company, I have no vested interest. nor intend to advertise for anyone or anyplace where I made my purchases

OK, I'll shut the H*** up now.
