Practicallicly NFT🤟BEST SYSTEM

What a weird world! Less than 24 hours from Hooch posting the video I am sitting here with a couple new Kratky buckets with lettuce in them.

The dwc bubbler may have also warped your pH.

dwc needs to be toped up daily or its not dwc

As always , thanks for the great vid! I live in an apt with limited indoor grow space. Kratky has been my go to for ease of setup and ease of maintenance. For much of what im growing a no refill set and forget Dr Kratky special hits the sweet spot of space and ease. I do have a few aeroclone/dwc boxes and those are great for longer growing projects but those need more care across the grow. I recently 3d printed the Hooc Vertical Light Saber Of Leafy Greens and am about ready to set it up, im curios to see how that fairs. Thanks again for the inspiration.

14:50 Up until there was a difference because the DWC ran out of nutrient solution, they were the same. I think an air stone helps prevent root rot of which neither got because the temperatures were reasonable because these plants were grown inside.

I'm getting .7 ec with masterblend tomato formula and tap water. Seems too low but it's working so far. Sets are a few weeks from harvest.

The Kratky system can be far superior to Deep Water Culture (DWC) if you can master two key aspects: 1. **Fine-tune the nutrient EC to the specific plant you are growing.** Since the plant roots are soaking in the nutrient solution 24/7, "less is better." Start with an EC of 0.5 (250 ppm on the 500 scale) and evaluate the results at the end of harvest. Then adjust the nutrient solution to EC 0.6 for the next crop and evaluate it again at the end of harvest. Continue this process, increasing the nutrient solution by 0.1 EC for each successive crop. The end-of-harvest evaluation should include the physical appearance of the plant and the taste of the produce. 2. **Use large containers, as "more is better."** You want to avoid running out of nutrient solution before harvesting your crop. For crops like lettuce, use a 5-gallon container and limit your grow to one plant. Evaluate the plant at the end of harvest, noting how much nutrient solution was left in the container and the physical appearance of the roots. If you have more than half of the nutrient solution remaining at the end of harvest, you can increase the plant count by one for the next crop, with a maximum of two plants per container. Avoid topping off or adding nutrient solution during your grow, as this will cover the air roots that develop as the nutrient solution decreases, potentially drowning and killing your plant.

I will see you next time on Hoocho's, that my friend is a fact. I love you approach and that you are willing to revisit a topic with new methods. It really helps inform, us the audience, that there I no perfect solution and they different methods may work really well in different circumstances. The root development in this DWC is far different than what I have seen in my own, but it is just a reminder that our plants are as varied in temperament as our pets and sometimes, they just do the damnedest things despite us doing everything the same as prior efforts.

Always keep your air pump above the water line. No additional parts needed. And ya, you need to top up DWC.

Shane is awesome! On a side note, what timelapse cameras do you use??

Given those results, my questions now would be how many days does it take to grow the head of lettuce, and how many litres of nutrient solution is required per head of lettuce? Personally, I would be inclined to use smaller containers with one head each, then stagger the start of each head of lettuce to create a perpetual source. Hoocho, I know you're growing on a much larger scale, but I'd love to see the instructions laid out for a "minimum viable product" for someone to grow with this method in the simplest possible way where the only goal is a fresh head of lettuce ready to harvest every day. And if you're staggering the start of each head of lettuce, I think a separate container for each one makes more sense. Or maybe netcups of different depths?

What filament do you use? Nice video!

Love the information you've provided for the Kratky grow. I've grown indeterminate tomatoes with and without the Kratky method and then placed the plants in a bed in my garden to prepare my grow tent for a new set up. Those plants are now producing new blossoms and are growing great.

Hey Hoocho. Absolutely love your videos. I have a question/thought. If you were to do this with one of the float valve systems, would the DWC have a better result? Based on the root growth on them, the bubbles splashing water on the roots at the earlier stages, and progressively shifting away as the water level dropped seems to have stunted the growth.

Since your experiment with krakty tomatoes i really dont see the point with DWC and airpumps. I much prefered the dutch bucket system which i now use and wicking raingutter grow, both only leaving a single reservoir to be check and topped, and just using a krakty for simplicity and not having to setup, waste power and money with airpumps

Dude, this is not DWC. In a DWC system there is no air gap above the roots. The roots always fully submerged into water and receive all the necessary oxygen only from the bubbler. en.wikipedia.org/wiki/Deep_water_culture You built the Kratky system, only with bubbles.

Thanks for doing this, basil grows really well in a Kratky system...

Further improvement, add a hole to the 3D print lid, so you can insert a support rod for veggies that require it. Can start off with a small hole. So if someone needs a larger one for a garden stake, they can take a large drill bit, and the small hole would be a good guide. Fantastic video as always.

There are a few ac/battery powered air pumps, when the ac/grid fails the battery pump takes over and will supply air during outage. Simple plug in air to a one way valve and tee it into current air system. Also one way valve the ac/grid pump to keep from leakage while batt pump is operating 😉

If you go to any effort to set up air pumps, its not to much to ask for an autofill float valve from a reservoir of nutrient solution to make the deep water culture system stay topped off with gravity alone. That would be a better comparison cause the dwc would stay dwc and not some hybrid dwc/kratky. This proves hybird dwc-kratky is bad.

I think since the water level dropped so much the deep water culture is no longer "deep". Think it would have done much better if you topped it off periodically, though I understand the purpose of the experiment was set and forget. Cannot forget about systems that require attention....deep water is one of those systems.

Yeah uh... if the nutrient mix is getting depleted that much, that's not deep water culture, that's an aerated kratky system. Deep water systems need the water level needs to be maintained consistently so that it never drops. By any amount. The roots need full submersion at all times. But yes, DWC is a more complicated setup. 100%. It's not really a good method for small-scale usage.

Do you have a nutrient blend you created or one you would recommend?

It is hard to beat a "set it up, then harvest the lettuce" ease of the Kratky method. Why in the world would you bother with air pumps, air stones, tubing, running electricity, etc. when you can just plop the lettuce in the Kratky pots and that's it. I don't get it. Where is the value in the pump method????

I grow lettuce Kratky style for our farmers market. I always wondered if adding air stones would be beneficial, but we are off grid and don't have the spare power for it. Even though I am a huge fan of Kratky, I am surprised at the results. Thank you so much for running this experiment!

My lettuce is in DWC. I keep my water level the same through the entire grow.

Really great video again! I like your openness, and creativity, keep goin'!!

I wouldn't have guessed that result either. Lettuce is well known to perform very well with low oxygen content in the root zone, i wonder how much that factor played in the final result Also a 3d printer would have saved me a lot of time and money when i was seriously experimenting with hydroponic and water filtration a decade ago, and it's nice to see someone talking about ventilation, since plants need light, nutrients, water and... air!!! - everybody wants the best nutes, light or wtv but how many have really invested in ventilation

The STL file on your patreon are they editable ina cad designs. if so how. i would like to make joinable T and Cross junctions

One major drawback of DWC is with the bubbler constantly pumping oxygen into the nutrient, PH will keep rising.

What were the ambient condition in your lab during this test (temp. humidity atmospheric pressure etc...)?

Great video! How many days did take until maturity?

Do you have any organic hydroponic fertiliser trial?

Thanks for inspiring me to design and 3d print my own net cups. I never realised bunnings buckets were so cheap!

Amazing video, cant believe the huge diference

First time I've seen a video where kratky came out on top, which is great, because I love the set and forget

Im doing lettuce in a foam broccoli box it has four holes net cups have biodegradable nursery bag in them filled with coco coir and perlite and then topped up with anarchy nutrients

Hi Hoocho, new here, loving the channel. You’re correct about 3d printing being cheaper, I wanted a hydroponic tower but in the uk a decent one is around £800. I brought a secondhand p1p for £300 and some filament and designed my own. Currently printing it at the moment and I recon with the coast of the printer and filament it’s going to coast me around £400 for the tower and I’ll have a 3d printer out of it to make more stuff.

Nice 1 Mr Hoocho. Excellent results on the least hassle Kranky system

I think the biggest issue people are going to take is that you setup and ran the kratky systems the way they are supposed to be run but didn’t run the DWC systems the way they are supposed to be run. It shouldn’t be called a comparison between the 2 methods and more so a test to see if a bubbler aids kratky production, which in this example it doesn’t. That being said I like the prints and that’s what I’m really here for. It would be cool if you could find a way for us to use the prints for even smaller beds. Like some kinda modular setup

isn't DWC better for warmer climates. My Kratky strawberries and watermelons all flopped due to the heat.

In my experience, Kratky demands 60-80% of the EC Level you would apply on a DWC system. Regardless of the plant you grow.

The buckets are looking great mate, but you've got to upgrade to one of gathera's new netcups! Made for 34mm diameter holes, will solve all your algae issues!

The episode I wanted. Thank you.

Just a heads-up, you spelled "comparing" wrong in the thumbnail.

BIG DOG!!!! IT'S TIME!!! THE VIDEO WE HAVE ALL WAITED FOR!!! I grow my chillies in dwc. I've always wanted to know the difference and if it's worth going to kratky

Hello Mitchell, everything is ok I hope. I tried to reach you via messenger, via email, but no response, so I thought I'd go this way. I have 3 messages hanging in the FB group. Awaiting approval. Why wait where it was automatic before, I have no idea. For example, I have not said or done anything not done. There is even a message from April 28, 2024 that is awaiting approval. Greetings and keep on hooching, Denis

I think the potatoes didn't grow higher up in the mulch is because the mulch didn't wick up much moisture or nutrients. I don't think it has to do with weight. maybe try adding more coco and perlite ontop instead of mulch for next experiment?

I tried the buoy method. I put outdoor. But what happened was, the buoy got jammed, due to the mineral that got dried up. The buoy has small channel, it becomes easily clogged up.
