CPU fans...

The temperature in my fruiting chamber is around 83-84 F. I was thinking of using CPU fans. Is it necessary to use a computer power supply in order to use the fans? Kind of afraid to wire the fans up to plugs and popping them into a plug outlet.

How do you plan on using the fan? Like where are you going to put it, inside the FC?

yeah i'm waiting patiently before i go and start some wrong method haha
Maybe I should place the fans opposite? So that the fan blowing in the fruiting chamber will "churn" the humidity at top while air exits through the bottom.

Using a fan like that would take every bit of humidity out of your FC in about 5 seconds.

Ya but with a constant removing of the air inside your FC that wont do anything for humidity. Think of the humitity inside your FC as a smoke bomb let off inside it. Think about putting a fan blowing in on one end and one blowing out on the other. This would clear the smoke out of the FC VERY quickly. I dont think the Ultrasonic will be able to keep up in the least.

I had concern with keeping the humidity. Shall I just go about putting cups of ice in there?

DON'T plug the wires coming from the fan in the wall. Check the voltage and amperage on the fan first. Mine was like 9V 500mA, thats most small adaptors. You can see by the diameter of the wires coming from the fan that it is not made to be plugged into so much tension.

that probably wouldnt be your best bet. Fruiting at 83-84 shouldnt be that big of a problem at all if all your other factors are there. A cold shock might be very beneficial if your not doing a bulk grow. check the forum right below this one "fruiting in the heat"

hmmm...I apologize for not being specific.
I am currently using a martha stewart greenhouse whatchamacallit. I am doing bulk. Right now there is 7 trays wanting (i'm hoping) to fruit.

adding those fans is a bad idea, especially if youre trying to lower temps, right? i doubt its colder outside of your FC than inside, if so, change light bulbs or something.

its cool. i think you should be able to fruit at those temps just fine. search for hypaes pinning strategy and follow that. You should be just fine.

you mean "hyphaes" pinning strategy? on the hunt
*update* found the pinning strategy
"hyphae" states that a temperature around 77 F is optimal. very depressing since mine is around 84 F

84 will work, but much more slowly, like i said. pawn shops usually have window units for 40 bucks. plus they cost a pretty penny if you have to run them too much, but at 84, you could run it on a timer to adjust that.

There are numerous ways you can lower the heat in your house without air conditioning. First thing is to make sure you aren't heating things up with your lighting system. Low wattage fluorescent light on for only a few hours a day will be enough for initiating pins. Make sure you keep other electronics off and lights off open your windows to let cool night air in and get a fan going to circulate the air. Worst case scenario you will have to use frozen bottles of water.
I've fruited in temps that varied from 80-82 degrees last summer and this past winter I was fruiting at temps ranging from 60-65 degrees. What I'm saying is that temperature hasn't been a big issue for me with cubensis. Strain may or may not make a difference but if all else fails...B+

yeah, sorry. you dont need a AC unit, my summer temps were in the hundreds, i had no choice. musher's advice is right on.

the martha stewart is in my closet. right now i got a cup of ice to see what good that does
i'll open the windows tonight.
as far as electronics are concerned; the bedroom lights are the only electronics active.
i live in the midwest so the area is a bit humid and hot over here, but it does cool down at night

Definitely don't try to connect a CPU fan directly to a wall outlet. The fans probably need 9V or 12V (be sure to check which), and the wall supplies 120V. The wires in the fan would most likely immediately melt down and catch fire.
Also, wall outlets supply alternating current (AC), while the fan needs direct current (DC). There's no way it could work. =/

i am not the britest guy but i thought i read some where that some one hooked up a power supply from like a cell fone changer or what ever to the computer fan. guess it worked. i have 1-2 computer fans laying around with wall plugs dont sure they where my step dads, dads fans.
going to bed now will get a pic up tomorrow
(and they work) no prob with them but i use they to blow air in my repti. cages.

A cell phone charger isn't a bad idea; that would work if it is the right voltage.
Pretty much any time you have a power adapter / cord that connects to a wall socket and some electronic device and has a heavy box somewhere in the middle, what you have is a transformer that converts AC to DC.
So anything like one of these things is a transformer: they take AC from the wall and spit out DC at the end that connects to the device.
Now all of these have the voltage they put out on the DC end written on the box part. If you look closely at the second link you will see that it produces 9V. The third one produces 8V. The fans may have the voltage they need written on them as well.
So if you happen to find a transformer that produces the same voltage the fans need, you can wire the fan right up to it and it should work fine. If you don't have any transformers lying around that you want to butcher, you could get one of these configurable ones which can produce several voltages. Much cheaper than a PC power supply.
So yeah, you're on the right track with the cell phone charger idea.

I don't think fans will be such a good idea anymore; the humidity in the chamber will have an exit. Currently I am using cups of ice to cool the FC down.

Those ultrasonics have a way bigger fan on them than a pc and the element can pump out a ton of water. In my experience, their almost too much, like a fog where everything is wet, instead of humid air. I tried running a FC with a little one and with an outlet, everything just got wet. filling a sealed chamber with fog was better, but still too much, too fast. in the end i used a fogger, the kind you can put in a bowl of water. as soon as the chamber started to fill with fog i stopped, cause thats when the air was at saturation, otherwise the fog would rolloff and disappear, meeting with the drier air in the chamber. Realistically though, the cheapest and most effective method is just a nice 1/2", saturated vermic and/or perlite bed and a jar full of water with a fish bubbler in it. little sprits from a spray bottle between openings and it was all good to go. You can even substitute the bed with water crystals but i havent tried that yet.

Could you explain why you don't recommend ice? It did a nice job dropping the temperature 5 degrees.
Also when I open the FC, it is hard to make out any foggy characteristics. I do feel the humidity, but the only sign of humidity by the eye is the collection of moisture on the surface of the FC (inside of course).

well... i dont just cause it takes up floor space, and i dont normally monitor, i just set a stat . but if you know what your doing then ice can work well yes.
as for the foggyness, its the fog that rolls off an ultrasonic element. when the FC looks like a foggy london street, its just oversaturated, cause you can see the water. thats why i cut the fogger when i see too much fog, cause it just makes everything wet, and causes puddles. you only want a little fog at the base of the fc, really. at that point, its not gonna get much more humid, and its gonna start getting wet.
can anyone help me support this or am i on a rant?
