Many of us here have made use of the DIY fogger system in order to increase RH in enclosed growing spaces. Unfortunately depending on your location and/or settings, the water can potentially drain rather quickly. In my experience I have to usually refill a 5 gallon bucket once a day in order to keep my chamber humidified. Granted adding an air conditioning duct in the chamber decreases the RH but it is my only means of cooling for now. Needless to say having to refill the bucket daily is no different than having a needy girlfriend!! Adding to the mess, should I have to leave for more than a day or two, there is a chance that my RH would crash until I could refill the bucket.
I went out and purchased a few bits and parts at my local lowes to attempt to create what is essentially a large water reservoir (much like a toilet water tank). Using a float valve, water enters the bucket until the floater rises and closes the valve cutting off water entry from the reservoir.
Below are the items I purchased and assembled along with some pictures. I don't believe this requires MUCH explanation or different angles but if the design isn't clear, please ask and I will gladly post a short video/extra pictures. Just tried it out and it works like a charm!
1 - 32 gallon trash can (you can go bigger if you want but I chose this due to space constraints)
2 - I.D. Hose Barb MIP Adapter 1/4" x 3/8"
1 - 90 degree Brass Pipe Elbow (Brass will not rust)
1 - Float valve (purchased online, the smaller the better as this had to fit in a 5 gallon bucket)
1 - 1/4" hose (length as needed)
1 - Bag of hose washers (plastic)
1 - Tube of silicone (waterproof, you can NEVER have enough!)
Be sure to drill the holes in the bucket and trashcan SMALLER than your pipe fittings. It is better to thread the plastic and seal any small leaks with silicone and a washer than it is to have a large hole with a bad leak. Also be sure to try your new system before putting it to use!! No one wants a 32 gallon mess to clean up
If you find any leaks (drips or streams) simply empty both your bucket and reservoir and apply a generous amount of silicone around the seams.
Thanks for looking
