Here's some pics of the plastic.
2- 4'X4' grow trays and lids. 138 plant site each side 276 Total.
Mister nozzles are plumbed in the lid, fog thru large pvc pipe.
note the cool "root gurards" for fog inlet....oldmac's root spa!

I've seen, in person, demonstrations of both sytems before. The original Frapa fogger was designed in Isreal (where I saw It) and was later made under parternship with Canadian plastics mfg. It's a true 5micron or less fog.
Ain't cheap.
Mister Nozzle's like Bete, produce "some" sub-5 micron, but the majority of the fog or mist is 5-50 micron. Natural fog is said to be abt 30 (your micron's my vary)
You said it above Opie: The fine delicate roots love oxygenated moisture (and even co2) but there are also larger/longer tap roots that like drinking water. Figure give them a drink of wet fog.
As to clogs, first if you use a pond fogger, change the transducers right away. Second be very carefull with what you use.(no olivia's!)
I'm pushing things with the nozzles I'm using, orifice is just .012. Key here is good filtration before pump...I'm using a 5 micron sediment filter. BTW, these brass nozzle's are probably overkill, they cost 13.50 each in a lot of 36. I'm using 8per tray, 16per fogfognugen, and I will be building two. Also, I'll be running very light nutrient solutions, abt 20% and I plan to utilize more foliar feeding (for various reasons).
The proposed schedule is Frapa fogger 10 mins on (@10min after the hour and 1/2 hr) every 30 mins. 24 hrs a day, don't want roots to dry out during dark period, even if they are not feeding.
Mister nozzles 3-5 seconds every half hour(on the hour and 1/2 hr) on photocell=only when lights are on. Photocell in cycle timer syncs with other timer, when lights come on.
So for example start at 7:00pm lights come on, first event is mister pump for 3-5sec. !0 mins later Frapa starts, runs 10mins and stops. 7:30 mister pump, 10 mins later etc etc.
Here's a place with various size foggers, maybe give you some ideas. Those small size room humidifer's are not too expensive and could hold promise. Plus they have pond foggers up the wazoo. Mainland Mart factory outlet and wholesale supplier
Wow Opie you are right. Everyone jumping in at the same time. heheQuote:

Yeah, and you got me doing it now.
You know, maybe you should have started it in "Advance Tech".....
........I know I would have seen it sooner.
Yeah, let's keep the good ideas alive.
Wow!
Dude!
Wow!
Weeze
They say your not crazy if you talk to yourself; it's when you start answering back when you need to start to worry... lol... I guess I need to start to worry cuz I'm always answering my own rambles..
I too am interested in fogponics Haven't lost sleep over it like you Opie but I know what you mean ... My brain is always running about projects I'd love to get goin in the CULTIVATION STATION.. I'll definitly be subscribing to this thread...
Thanx for your posts too Opie, I've learned alot by lurking as you and the usual suspects help others in their adventures in this great hobby... After being a dirty boi I think h20 is the way 2 gro, indoors at least...although I'd like to try hydro outdoor from seed some day go for size..
But fogponics is definitly the future, And I'd love to bear witness to the revolution...
Later D:S5:
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?
These photos are a time lapse from ignition to one minute.
These photos are at 8, 15, 30, 60 and 90 minutes. I never really noticed much of a change after one hour. Will it fill up a 29 gallon tub in 3 hours? The good news is the container appears to be mostly filled up. I never really saw fog coming from the lid that was closed except for a tiny crack. Once the lid was open though the fog rolled out a bit.
I know, wow, a lid. Well these photos show the progression and they are also taken at 8, 15, 30, 60 and 90 minutes.
Comments please. Goodnight.
Uh, recirculating that is.Quote:
