Hey guys check this out



I wonder if this really works, i have one of these things sitting in a box in my closet. I didnt think you could evaporate the nutrient solution though... just postin to see if there are any thoughts. Its cheap, and if it works could do really well

yeah ive seen this before its pretty cool concept. you can also use those micro-fogger discs that can go in nutrient solutions. if i remember right there problem is that you need the fog to be certain sized water particles. i dunno if the humidifiers break it up to that size but i would love to see someone try this out! excellent find

Thank for the props, i am looking at going hydro for main part of my setup and been looking around. This looks perfect for me, if it works, I do believe i will try it with some clones.

Hi there Joe there is a thread going about this same subject DIY High Pressure Aeroponic System (A Work in Progress)

I'm certain you all could get something out of this video too so please re post in that thread if you like. Good luck it looks interesting there are many options and innovations out there for the DIY'rs.

Sorry mate didn't know there was another thread like this, i will check more careful next time. I will refind the link and post it there to see if anybody else is interested

I started messin about with one of these today. Found an cheap water vaporizer at a 2nd hand store, still looking for a cheap cool mist humidifier, and same with the ultrasonic dry mist type too. I plan on trying one 24" x 14" x 18" tub done the same way as the video above shows. Heres the pros and cons to each so far

Warm Mist

Pros: Good in cold grow climate (below 50 Degrees F)
Much higher humidity out put the other two
More common cheaper unit
Seem to be able to use regular nutirents
Easy to adapt to resivior

Cons: Heat, Heat, Heat (the mist is thick but about 80 Degress F)
Uses lots of power
Have to cycle (8 hours on 2 hours off)
Resivior is clear so alge growth happens
Resivior is small so have to either refill constantly or rig auto refill
Check PH daily
Doesnt Shut off when you run out of water


Cool Mist

Pros: No heat (uses evaporater pads)
Easy to refill resivior and often have larger resivior
Small power useage
Dont have to cycle
Alge not a problem
PH not a problem
Built in fan helps circulate air in the chamer and provide O2 to roots

Cons: No nutirents, need to hand nutes or add have drip system for nutes
More expensive
Least humidity output (most often around 3 gals per 12 hour)
Likely need added drip system for extra watering
Harder to adapt to resivior



Ultra Sonic

Pros: Nutrients work
More himidity (not as good as warm mist but better then cool mist)
Easiest to adapt to resivior
Lower power requirement for increase humidity over cool mist
No pad or filter to change
can rig a back flow to keep humidifire res fuller longer
Can pipe foger to fog chamber from distance (no more then 5 feet)

Cons: Expensive (about 50$ for a cheap one at local store)
Alge can be a problem
can clog with wrong nutrients
may need special nutrients to get good levels and not clog
Special nutrients expensive
check PH daily
some heat issues

Like i said i plan on trying all of these to see which works best.

by far the cheapest is the warm mist version. You can get the used Vaporizers for like 3 dallors at 2nd stores, and less then 20$ at Walmart. But what you gain in savings you lose in electric needs, you also need to cycle because the recomended workings are not for over 8 hours.

The Cool mist are the next best money, and also they use by far the elast energy. You will need a secondary drip system for nutrients if your not just cloneing, which adds to the cost but only marginally. A cool mist humidifer cost about 20$-30$ at walmart depending on size (the bigger the better in this case, due to larger resivior and higher GPH) i would almost sugest getting two and hooking them into one chamber to provide more humidity. That increase cost however.

The Ultrasonic or "dry mist" are the highest cost, they use a decent ammount of energy, not as much as the vaporizer warm mist though. The unit itself cost the most at about 50$ for a small one, but you can rig the condensed water to back flow back into the resivior in order to not run out of water as fast. But for less power, with marginally less heat output, and about 2-3 times the price you get roughly 90% of the same humidity as a warm mist system. It is advised you use special nutrients though.

This is it so far. i am building and testing the Warm Mist for leeks and proformance tonight and will get some sort of plants in it to test how it preforms. I will take pictures and give detail construction notes of each setup. Not tonight though

Hi Joe please don't misunderstand me friend. You are posting interesting topics that's gr8t. Just trying to link you up with some other folks and maybe they can get something from these posts too.

Take care.

Ok so I just checked the Resivior, its been 3 hours since i started the Warm Mist and here are the stats over that time

Start: Humidity to start 60% (its summer and its humid), tempature 78 Degrees F, resivior state; dry

Humidity started to rise at 21 minutes when the water heated enough to start humidifying, tempature climbed steady until after that point to roughly 97 degrees F and held steady there ocasionally fluctating as water condensed on the tempature probe.

30 minutes: Humidity maxed on guage of 99.9%, tempture fluctations indicated alot of condensation. It was literally raining in the tote at this time.

1 hour: condtions the same

3 hours: condtions equalized at 100%+ humid and tempature of 98.6 degrees... literally the same condtions in a persons mouth.

No PH test on the condensed mist, because i dont have the proper kit so i dont know it Gonna get one tomorrow

Had added 7 tea spoons of standard liquid fertilizer consentrate to Carbon filtered PH nutral water With bring it up to standard 10-15-10 according to directions on the bottle. I believe this even if the nutrient transfer is high this will not be enough to support proper growth and will have to be tinkered with. nutrient transfer levels not yet known.

I am hopeing to get a cool mist humid tomorrow from another second hand store which sold them last time i was there. Hopeing to find an ultra sonic one cheep too because 50$ for a small one is way too much if your trying to do thsi on the cheap.

So heres the run down of how it is gonna go

Step one: buy materials and construct 1 of each type of discussed "Fog-o-ponics" system. One "Warm Mist", one "Cool Mist", and one "Dry mist"

Test each before planting, get each system in working order, make complete parts list with rough prices and cost.

Step two: Test a non-canabis produce inorder to not endanger valueable clones, and get nutrient levels and procedure down inorder to operate. Also to get lighting levels and system worked out. Kinda like a dry run.

While doing dry run begin 18 clones, 3 from each mother (Blue Chronic and Desil) for each system. Six in all. That gives them 8 inches side to side and 7 inches front to back. Get clones rooted and started in root cubes, and veg for 1 addition week to ensure strong root system.

Step Three: Move to systems all at once and turn them all on. Vegitate for 6 weeks

Measure progess of each plant in each system, recording growth, health, and matinence required for each system for each week. Post at the conclusion of this the stats

Step 4: Convert to flowering. Flower until done. Both strains have reported the same flowering time of 8-10 weeks. I will measure any changes, how fast flowering begins, bud structure, and eventually harvest.

Step 5: Harvesting will be done as needed and totals will be taken, and posted

Thats the whole experiment. After that i will discard the two lowest systems and duplicate the best and then my reserch into the cheepest and best "fog-o-ponics" system will be done. Then likely on to other things... except i am gonna need alot of new friends to handle all that bud.

That is a cool DIY aeroponics system for sure. But for cannabis growing, I don't think it will work. My understanding is that cannabis needs to uptake a lot of water (nutrient solution), so in order to feed a cannabis plant (in flower) enough nutrient solution using a hydro atomized nutrient solution (nutrient solution broken up into droplets of less than 50 microns), you need high PSI lines running to whatever is producing your fog/spray. I just don't think you will get enough nutrient uptake to allow for the type of agressive flowering aeroponics was designed for.

I think this system (as previously stated in this thread) would work well with another form of hydroponics. Either ebb&flow, such that the roots are always in the fog, and get flood/drained a few times a day, or a type of top feed (cycled on and off) perhaps.

Yup i am comming to that conclusion, that a secondary drip irrigation system would be needed for each system. The Warm mist system would require one in order to cool the plants them selves. The Chamber approuches 100 degrees while in operation so a second resivior of 60 or lower degree water at a slow drip irrigation rate constantly would be the only way to keep the heat down so the roots didnt just die from condtions. The Cool Mist system dosent handel nutirents by itself so a drip irrgation system would be required for anything after cloneing. The dry mist is yet unknown. Am building the systems themselves tonite. Have things up and running in a couple weeks. I will keep in mind that this is a long shot, but then again most new stuff is.
