Aeroponics vs DWC

[t.o.med]

squarepusher- the problem i see is dialing the thing in too much and your going to fry the plants. dialed in i dont know if you would even need a water chiller for your rez. did you read the pdf on recirculating aquaculture ? if you run this dont bother withany benif-baccteriathe ozone would kill it.i would test it first. i didnt see were it said how much oxygen it adds. im goig to read some more about it see if i can find out how often it needs to run and what levels. how many gallons of water in your system? definately an interesting unit. maybe jalisco kid will chime in on what he thinks.

so, essentially aeroponics is better than DWC. I'm guessing, the only possible explanation for this would be more oxygen. What if we added more oxygen to our DWC's? Like, several air-stones per tub? Would we be improving?


I wonder if its possible to do an aeroponic tree grow? Think, an aeroponic cloner tub, say 20 gallons except for 1 plant only (tree grow). Say, 8-10 sprayers per tub. Would this be feasible/effective?

i got the rainforest 318 and use organic nutes i personally find that this system is an aero/dwc setup it suspends roots in 100%humidity but the roots grow down into the resevoir essentialy becoming a dwc bucket as well and yes adding more airstones to dwc buckets will help acheiving a heavyier yield / i have pulled half a pound off 4 plants that were no taller then 18 inches[roots were 6 1/2 feet long though] so you can yield with aero// and yes you can do a tree also go check out dr greenthumbs super green crack grow journal shit is crazy:passingjoint::cool0010::character0053::hunter:

I hate to say it but your all wrong. Yes there is a small gain in 02 avail to the roots but the big thing is the nutes are atomized and pass into the roots much easier. Ive grown "trees" in 5 gal aero buckets and will be changing over to 60L soon, root mass is huge. DWC is much easier to set up and run, imho most people should stick with it, only go areo if your really know whart your doing and play around a little before you invest lots/

What do you mean the nutes are atomized? JK

The basic principles of aeroponic delivery are the rapid exchange of gases between the membranes of the root subculture and the plant roots. Application of a micro-fine nutrient film that is readily absorbed and evaporated before the next aerosol cycle is the goal.

The need for 50µ-target size for micro droplets is based on the findings by researchers that the average tube opening on the root hairs is approximate 20-50µ or within a range from 5-100µ.

The specific reason for this importance is as follows:

Aero isn't about DO. There really isn't that much in True aero, as I've mentioned. It has to do with uniformity of droplet size.
The mist that is created by these nozzles is micro fine and all the drops are pretty much the same size and an ideal size for optimum uptake.
You have a hundred different size balls that you are trying to get through a screen with holes that only fit things the size of a ping pong ball or smaller. Your standard mister is going to have like a 50/50 mix of sizes and the bigger ones have to hang out until something comes along to break it into several smaller balls kind of like the game 'asteroids' if you remember it.
True aero is a spray of balls that are all the size of ping pong balls or smaller, so everything goes right through the screen without having to wait to be broken up into smaller pieces.
That is what is happening on a microscopic level at your root level. The need for O2 is that it breaks down those H20 molecules and helps tear apart CO2 the O's are all what they call 'Free Radical' Meaning they bond with anything immediately. It is called Oxidation. That is why your blood is red, oxidized iron in your blood. It is how hemoglobin is created. All cells respire gases...it is smaller than water vapor or even the molecules themselves. O2 is a gas, CO2 is a gas, Nitrogen is a gas, Hydrogen is a gas these are all gases that when combined together to make a 'big ball' make water H20 or CO2 or any of the elements you are feeding your plant.

Aero is all about the o2. the droplet size plays a part but the controled delivery of the microdroplets is more important. if you have the proper droplet size but arent able to deliver them in controlled bursts you wont get any different root stucture than if you ran just lp sprayers.if you follow the advise in that link youll never get roots that develope fine root structures. IMHO the guy never ran a true aero so i wouldnt pay to much attention to his advise. you cant grow to big of a plant in a 5 gallon pail with true aero. my last plants were only 30 inches tall and filled a 22 gallon container. (pic included) those roots were like cotton candy. nothing bigger than a pencil.

other pic is my new test subjects roots after 6 days in the high pressure aero pods.

problem with true aero , its hard to get good root coverage with the sprayers once you have any significant amount of root mass. That is, the roots block the sprayers, and you basically get drip down for most of your water (not tiny droplets)

I believe in a properly designed system you can overcome that by basically scrogging the roots. something im working on now. the containers were definatly to small for that size plant but there was never enough water to drip down. if your able to control the atomization and delivery rate even without the mist directly hiting everypart of all the roots the roots will develop air spaces and not mat up where the humidity will still stay in the 80 percent range and be able to absorb moisture. the inside of that fluff ball remained white and healthy even though the mist towards the end was not hitting them directly. we'll see its all just fun now.

sp- i was looking at something similar awhile ago but it only measure orp,do and ph cool units but there not cheap thats for sure.

wrong about what exactly.

 

[scoobydoo]

I was just trying to point out there is more to aero then extra o2 and everyone goes off on some rant. I was able to get 2.5lbs from a 5 ft plant in a 5 gal setup, not true tag, but thats a pretty good tree imho. As mentioned Im moving up to 60L containers. Anyways on topic with the thread, stick to dwc for now, the ease of it is unbeatable.

white leaves?

Awsome root pic tree farmer! I am running a similar system and cant wait to see results.

One question. The picture of the huge and healthy root mas, why are the leaves in the back ground white?

Photo shop or paint?

the pics were taken with a HPS going in the room hrs after the chop. my camera has a setting to try and correct for the yellow HPS light. as far as white leaves i dont see white leaves. some photos were taken with the filter on and some with it off. Im sorry if you feel decieved some how. that photo was posted to illustrate a 5 gallon bucket isnt probably big enough for a true aero plant. heres some pics after the chop to show what the same pic can look like with and without the filter setting with an HPS going. and some pics of the live roots before the chop with no hps just camera flash.

Now it be nice to see this similar system you have.

to be or not to be?

some nice root porn right there. What pump do you use tree farmer?

its a small diaphram pump. you can see the whole system under a thread here called "trees and aero".

just bought a DO meter, should get here next week. Will be able to do some good experiments with it.

What do you mean the nutes are atomized? JK

well on my system i use a vortex water pump and what it does is suck up water and drop it onto a plastic plate that spins super fast when the water hits the spinning plate it atomizes into a super fine mist creating a 100%humidty chamber by atomizing the nute water it makes it that much more available for the roots to absorb:anim_19::anim_19::anim_19::anim_19::anim_19::anim_19::anim_19::anim_19::anim_19::anim_19::anim_19::anim_19:
