Thanks very much to everyone who's stopping by. I'm glad to see others are interested in fog. And oldmac, wow, thank you for taking the time to share your knowledge and photos. I'm going to read that more carefully when I'm more awake, but for now I've got to get this posted and get to bed.

The fog units came today and Iā??m doing a little testing. I planned on putting one in a veg res and one in a bud res, but I have doubts that one singe-head unit will be enough. Iā??m hoping to get away with putting a unit or two in the chamber with the roots instead of building a little pumping machine like the $300 Nutramist thing. As I mentioned though, Iā??m worried about temperature, and I think a separate pumping machine would solve the heat issue.

So some things Iā??m testing are:
1) Will it make fog rise 14 inches above it an a largish container.
2) Will it fill up a container enough to make fog spill out an opening in the top.
3) Amount of time needed to fill up a container.
4) Temperature swing in reservoir.

I made a float for it from some packing that came with my T-5 fixture. The fogger is sitting in a 3ā? net pot. I had to cut a lip in the circle to get the fogger low enough for the proper amount of liquid to cover the sensor. The sensor is supposed to be 1-2 cm below the surface which is roughly 3/8-3/4 inch. The unit shuts off if the water gets too low.

The first thing I tested was fog output at various water levels above the sensor. I assumed that the closer the surface was to the sensor the greater the fog output would be, but I was wrong. I wasnā??t being scientific or anything. Iā??m just going by what I perceived, and it seems like thereā??s a little more fog when the water level is closer to 2 cm rather than 1 cm or less.

I didnā??t realize it would splash so much. You could put a couple of these in a small cheapo aerocloner and you wouldnā??t have to use air stones for the bubbles. Iā??m seriously thinking about trying this. Iā??ve read several places that fogging alone is not really good for rooting cuttings until they show some roots. The dry fog just doesnā??t keep em moist enough. If I recall correctly though, the people that have been saying this have been pumping their fog into the chamber instead of leaving a unit splashing in the res. If I did this, once the clones take root I would like a way to lower the res level or stop the splashing on the roots somehow. Seems like the splashing would defeat the purpose of a dry fog.

Iā??m testing in an 8 gallon container with about 1.5 gal of water, but the ones I plan on using in the grow are more than 3 times that size. Does this mean that it will take more than 3 times as long to fill up the bigger containers with fog, or does it mean Iā??m kinda silly for not just testing in the final container? For now Iā??m going to play dumb and assume the bigger container will eventually fill up.

One thing I found out pretty quick is that you donā??t want to have the cord positioned directly above the transducer (the water smasher disk-shaped thingee). I know, duh, but it just didnā??t dawn on me until I noticed that not much fog was coming out for some reason. The instant I moved it I noticed an increase in fog production.

Iā??ve been running this thing now for 1 1/2 hr and Iā??m done for tonight. By the time I get this posted it will be my birthday. Iā??m a bit surprised and pleased about the temperature. The res was 84 degrees at the start and only went up to 86. Not too shabby, maybe we can handle it, especially since the res will be recalculating and the test was not. I wonder if it would be safe to assume that for each head added to a situation like this you could expect an increase of 2 degrees. One thing I had not thought about before was the fact that the transformer will add heat to the grow as well. A 3 head unit may have an advantage in this department. I can probably keep it outside of at least the flowering area, but at the end the transformer was 121 degrees. Hmmm, do you think I could wire one transformer to run 2 or more units?
Opie Yutts Reviewed by Opie Yutts on . Should I get a Nutramist fogger? I've always wanted to try fogging, since it is the absolute best way to give your roots oxygen. The results are supposed to surpass common aeroponics and NFT. I'm ready to re-do my spray system, since that's not really aeroponics, and it gets plugged up. Upon researching pump sizes and what all is required for true misting, I'm better off buying a fogger. I guess the new thing is to combine fogging with NFT, but due to power outages I'm considering combining it with a shallow res for the last 2 Rating: 5
