My Homemade Aerogrow Aeroponic System February 13, 2008

Filed under: planting — Jung @ 5:14 pm

Pulling apart my Aerogarden, was quite surprised how simple it is… nothing more but a submersible water pump, same thing as my kitty water fountain.

After researching for a more advanced aeroponic (vegetation grows in 100% humidity air) system, was quite put off by all the high price tags, I decided to construct one from scratch. This is what I came up with:

*Growing Chamber (a black file tote from Staples for 13.99)
Staple's File Tote

*FLOATING FOGGER (19.99 on eBay)
provides the humidity in the growing chamber
Floating Fogger

*AIRSTONE, AIR PUMP, & AIRLINE TUBING (2.99 + 9.99 + 1.99 from 3rd party seller on Amazon)
provides more oxygen to the roots for faster growth
Airstone Air Pump Airline Tubing

*DIGITAL POWER CENTER WITH TIMER (24.99 from 3rd party seller on Amazon)

Digital Power Center with Timer

*HYDROTON & 3″ GROW BASKETS (9.95 on eBay)
Hydroton and Grow Baskets What is Hydroton?

HYDROTON®Growing MediaHydroton is the “expanded clay,” a lightweight gravel which is manufactured specifically for hydroponic cultivation. This media is the first choice for many commercial Dutch growers specializing in flower and vegetable cultivation. Not to be confused with many other kinds of expanded clay which look similar but which are often toxic, Hydroton is pH stabilized and releases practically no minerals into the nutrient stream; in other words Hydroton is almost completely inert - except for offering excellent moisture and oxygen capacity to stimulate healthy root development.

*GROW LIGHT
Grow Light
I got a high output 400w grow light system that uses both METAL HALIDE (blue light for seeding and cutting) and HIGH PRESSURE SODIUM (orange light for flowering and fruiting) light bulbs. There are lots of much cheaper lighting systems out there, Aerogarden uses only 32w fluorescent light bulbs, and things grow just fine. But I really want my vegetables to grow faster, I decided to invest on a good light.

update: These Metal Halide lights are really much better than the fluorescent lights, the plants don’t strech their neck toward the light like they do in Aerogarden — in Aerogarden, even when the lights are set very very close to the plants, they still move toward the light bulb itself, quite an unhappy sight…

These are all the parts you need!

———————————————————————————

NOW, COMES TO CONSTRUCTING THE AEROPONIC SYSTEM:


1. draw six, 2.8 inch circles on the cover of the file tote, cut them out with a box cutter (the only hard part… needs some elbow grease :-) )

2. cut a little gap on the side of the file tote to allow airline and wire of the fogger to go through.

3. fill the grow chamber with 3 gallon of filtered water.

4. close the the chamber with lid, fit the baskets in the circles, fill in the hydroton with seed filled foam in the center. Plug everything, and grow away :-)

I use General Hydroponic Maxi Series and FloraMato (Dry Concentrated Nutrient) for plant food.

My seeds from Burpee will arrive tomorrow, will keep you updated on the growth of my vegetables :-)

    my students are working on a NASA experiment, they have to design a aeroponic system to be used in space.
    I like the idea of the fogger, I’ll pass that on to them for their design. They have some cinnamon basil seeds that were in the space station and are conducting an experiment to see if the seeds from space grow any different then the earth bound seeds. I love your blog, I’m very interested in sprouts also, nice sprouter. Thanks for the great ideas.

    Dear SHunter,

    Thanks for taking the time to comment on my post, as many like to email me directly to avoid the pain of registering…

    This sounds like a fun experiment, are you going to post the process anywhere online? I would love to know more about it.

    I found this commercial unit, may be of help to you: Nutramist Garden. The fogger alone costs somewhere under $400, does what my cheap fogger plus air pump do, but is nicer looking I guess :-) I am thinking of adding the flood cycle with a water pump, it will be a nice upgrade to my simple unit.

    Best of luck on the experiment!

    Hi. Your homemade aeroponics system looks great. I was interested in the aerogarden, but it didn’t seem like much of a value for what’s essentially a bucket, lights, timer, and pump. A home made system might be just the thing for me. Can I ask, did you follow a design you found elsewhere or was it something you assembled all on your own? Your design looks like it’s using both a fogger and a airstone bubbler which I haven’t seen elsewhere so far.

    I’ll probably end up doing something on the Aerogarden scale, with the CFL bulbs, but with a true aeroponics mister/fogger instead of the drip system.

    One thing about your fogger though. Do the LED lights in that picture turn off? From what I’ve read it’s better not to have any light. With all the water and nutrients already in place, a little light in the root area and you have an algae farm instead, which isn’t good. :)

    Dear Danzilla,

    Yes, the fogger I have is the only kind I found on ebay that, even with LED lights, can be turned off. I know about the roots’ need for darkness, I got a black box for that reason. The roots of my vegetable plants are so healthy and large now, I think I will post a picture soon.

    I didn’t follow any for-sale plans that are available all over the internet, I just looked at all the commercial units, read what they do, and build one anyway. So far, it works amazingly, I am extremely happy with my very simple setup.

    have fun growing :-)

    hello. just was reading your site and doing research. a version of your design can be bought at:
    www.StealthHydroponics.com

    i too would rather build it for a custom fit.

    Dear sjsperry,

    I took a look at the site you provided, it is also a drip system like Aerogarden, but an improvement for sure with the air pump. I have to say, with experience, drip system does create water drip sound. Before the roots grow large enough to reach the bottom of the water for the dripping water to cling on all the way down, the noise is unbearable especially when the water chamber is that large…
    Thanks for the comment :-)

    how much water do you put in the container? Do the plants actually touch the water initially? or is the water just deep enough to float the fogger?

    I pour in 3 gallons of water that is already mixed with nutrition. But at about 2 gallon, the fogger is already able to float. I just don’t want to keep checking on the water level even though the fogger would automatically shut off when water is too low.

    The box is really big, 3 gallon is about only 1/3 way up. The roots of large vegetables (string bean, cucumber, and Patty Pan Zucchini) reached the water at around 10 days of growth. The rest of the roots are very far from water even now at 18 days.

    I sank a shallow bowl at the bottom of the water chamber for each of the plant now, so the roots of different plants won’t get tangled up like the way they grow in Aerogarden (just in case, if I want to move them to different growing chamber — if I came up with one :-) It is not necessary at all). Even though some of the roots have reached into water, the majority of the roots are in the air, and able to get the oxygen they need for fast growth.

    I am seriously thinking about updating my unit, on top of fog + air, add a water pump for periodical flood cycle for the roots, and keep them 100% in the air. I think I will get a clear box in a few days as the add on water chamber to monitor water level easily and keep the roots out of water completely.

    BTW, when the seeds were germinating, I cover each pod with a clear plastic cup to keep the moisture and warmth that was needed.

    Hope this helps… I am learning as I go :-)

    I finished building my aeroponic system this past weekend. I hope you don’t mind all these questions. Do you keep your fogger running 24/7? I was just wondering since you have a timer on the surge protector, do you give it a rest every so often? Your plants are looking great! Thanks for all the great info.

    Steve

    Hi Steve,

    I use both the timer of the surge protector (to set the lighting time, I keep it on from 12p.m. to 8 p.m. to fit my schedule), and another timer (that comes with my lighting actually, has easy 15 minute segment control) to control both the air pump and fogger.

    (the digital surge protector with timer I got is not really ideal, 2 outlets are controlled by “day” timer, and 2 outlets are controlled by “night” timer, and 4 more outlets are not controlled by anything and is “on” at all times. I originally thought it would have individual control of each outlet… But anyway, you will need two timers for sure, unless you want to keep your fogger and air pump running at all time, there is nothing wrong with that I think.)

    The detail setting I have found working quite well was posted on http://blog.junglin.com/jack-and-the-magic-beanstalk/ March 6 Update in orange color text. I update that post whenever I take new pictures. BTW, there are flowers coming out of the Patty Pan Zucchini plants already, only 3 weeks!! I will post pictures when they start blooming.

    I am glad I can help, growing veges indoor is too much fun! Good luck :-)

    You’re a genius! I can’t wait to make my own.

    Dear Lisa,
    Thanks! But it is really quite simple. Have fun :-)

    hey jung,
    I think this is a great aeroponics system!!!! I cant wait to try it for my shelf!!! I want to build one but to leave outside, that why i wont have to buy light. What you think about that, do you think it will work? I do have a question, does it mater if you use a floater fogger vers an ordinary mister fogger.

    Dear Neicy,
    Sorry took me so long to reply, your plants must have grown large by now :-) Without a floater, the fogger will be sitting on the bottom of the water chamber, it will be hard to monitor the water level once the roots grow mature and big (the water is supposed to be only 1 inch above the fogger). I would strongly suggest using a floater.

    Leaving your system outdoor and use the nature sun light is perfectly fine besides you may have to watch out for bugs, which is not going to be fun once they decide to live on your veges… I just had to “kill” all my pepper plants because I left them next to the window and some micro green bugs LOVE them, and I wash the plants under the shower everyday to try to wash them off, nope, they procreate like mad. So I tossed out the entire set of plants… I will never do that again…
