DIY HUMIDIFER/CHILLER FOR SMALL GROWS

This is a DIY Humidifer/Chiller for Closet or Tent Grows that can be made for under $50, & all parts can be bought locally most stores like walmart, radio shack, & pet stores or online.
I use this in my 360 cubic feet closet w/ around 400w+ of light. It can lower my temps from 80's to mid to high 60's, & raise my RH from 30% to 90% +/- a few %. The temps are maintained around 75-78, & my RH is maintained around 50-60%. I can regulate the temp & RH by controlling the fans speed, which is controlled by a Coby 12v dc regulated power supply (Output:1.5, 3, 4.5, 6, 7.5, 9, 12V DC)

This can also be modded into a clone box, by adding a 2nd Box of your size choise, & lightproofing it, lid too , & cutting holes in the lid to for clone sites, & connect them together where the fog enters the 2nd box. Or it can be used to grow bigger plants, by feeding the roots w/ the fog, by adding nutes to water, for a o2 rich water fog.

Parts List:
Ultrasonic Fogger - $25
Fogger Float - $6
60mm Axial Fan (52cfm) - $2
12 quart Rubbermaid Container - $4
12v DC power supply - $4-5

Ultrasonic Fogger.

Fogger Float.

12 Quart Rubbermaid Container.

Rubbermaid Lid (underside view w/ 60mm Fan).
I just cut a hole to match fan size & screwed fan to lid (intake), & then cut out a hole on oppisite side for exaust. I used a party cup for a spout, but pvc or other material can be used.

Fogger inside the Fogger Float (holds fogger at the right water level for most fog).

Heres a shot of the diy humidifer/chiller in my hydro hut, w/ it off & on. this was a test run to see the dif between it off & on.

i let the 400w hps hut on for 20mins w/ the diy off humidifer/chiller off, to get it to the running temps & RH, which where 79.1 % 43% as u can see in pic.


heres the shot w/ the diy humidifer/chiller on (only for 10mins) & the temp dropped from 79.1 to 77.9, & the RH rised from 43% to 52% in 10mins, & would prob change more if left on longer, but i had to leave.

u can make this unit more effective if u where to use more than just a single head fogger, i think they go up to 5 heads. mines just a single head, so imagine a 5 head fogger.

im not sure, but my buddy spent around 100$ each or so for 2 humidifiers, & he still couldnt get his RH up past 30%, & was having to fill them every 12hrs w/ 1 1/2 gals of water. so he returned them & made 1 similar to my setup After i showed him, & he is super impressed w/ the results & only has to refill his res every few days, & now has an rh of 60%

Also if the RH is low enough in the area you live in (read desert) you could build an evap. cooler. I have one posted in my second grow journal. It worked really good and only cost about $20 to set up. It will provide decent cooling and a real boost in the RH.
