Thanks for taking the time for us. I have an aeroponics system, it grows well bit on a small size. I am all set up for the kratky but wasn't sure if it would work. Now I know. Thanks

How is this a good test when the dwc died and the soil was not watered enough. Without each growing style maintained correctly it's flawed from the start.

Not only that but his aeroponic. system was a hybrid of Dwc guarantee the roots were in the water so it wouldn't be as good also no water temperature control so none of the systems expect for the drip were running at optimal conditions which is crucial in dwc as water temps dictate the amount of dissolved oxygen where as the drip doesn't rely on the water to get it's air

Not too surprising considering that the Aero an Kratky were positioned to get much more light, which would easily be the limiting factor in this particular setup.

I'm an analyst and I love the data

did you run the fogger 24/7? or cycled?

I love how scientific this video is.

If you do this experiment again maybe use tomato cuttings.

sounds like a failed experiment. the drip would likely have gotten 2nd place if went to harvest and the DWC would have likely been in 3rd place if it didn't run out of water. A DWC is pretty much a kratky that uses air. which would help the plants grow faster. Other than this coco coir would most likely be the closest thing you'd get to aeroponics, that's if you do it right. aeroponics and coco coir are the hardest to master but if done right can produce 3 times the amount of soil.

Just about to run a somewhat similar test, Doing kratky vs aero high pressure at 50micron/100PSI vs cheap fake-aero setup with like 10 psi pond pump and basically a sprinkler head. Probably no question the high-pressure will do better; but the question is how much. Does it justify the 3x-4x cost when just growing veggies. My current hypothesis is it makes a lot more sense to run HP aero when your crop is a bit more valuable then a "tomato" and even a marginally larger yield easily makes up for the added cost.

1) I definitely appreciate the effort and the attempt. 2) The results are worthless and people trying to make decisions should disregard it entirely. Again, no shame -- science is hard and you were trying, which is more than most people can say.

Which tomato seeds are the ones that give so many tomatoes without overgrowing the plant? My tomato plants in the Kratky method grow big, go up to 2 m or more and many of them don't even grow tomatoes. They form some flowers that eventually dry without bearing fruit. And what formula of mutrients did you use that worked on both tomatoes and lettuce? I use different formulas and yet I have almost no tomatoes. And with these solution temperatures in the range of 25 degrees you didn't have Pytium problems? In hot weather, even with H2O2 added to the solution I have terrible Pytium attacks on the roots.

DWC without a doubt will grow your plants faster and give more for your return. The problem with DWC is maintenance. You need proper water PH specific to the plant you're growing. It's also important to properly balance the PH of what ever medium you use to hold your cuttings/seeds like soaking your hydroton blocks in ph balanced water for 24 hours before introducing a seedling. The temperature of the water could also be specific for certain plants so that's also something to look out for.. There are different nutrients for different grow phases which means completely changing your water multiple times. You need way more oxygen (best to line the bottom with bubble stones) and light that will feed the plant the energy necessary to process perfect nutrient absorption . It's best to use a combination of HPS and Metal Halide lights and stay FAR away from and low wattage low lumen lights, like LED or LCD. I use HPS for the grow phase and Add a metal Halide half way through the grow. It's also important to add a water pump to the bottom of your reservoir to deliver nutrients to cuttings whose roots haven't touched the water yet. If you do DWC right, it literally has no competition when it comes to yields, growth, and time. Nothing else touches it.

That just depends on how you look at it. With DWC you will be out of the grow phase weeks or even months before other methods. You'll spend less time in the long run on dwc because your crops will be done growing much sooner. Also the yields are much much higher, so you get more (usually much more) from 1 plant vs 4. This is just my personal experience and i've grown all sorts of crops dozens of different ways. Kratky and aeroponics has dwc beat on up front cost,user experience,energy, and maybe space, but DWC is king of speed and yields.
