What happened at 21:13? Looks like you had to add supports? :)

Only took 7 minutes of rambling until the video started 🎉

Why not use say Coke to lower pH? Baking soda to raise it? Vinegar to lower. It's not the space program people. No need to buy pH up and down $$$$. Simple stuff you already have at home.

Isn’t this kind of food terrible for our health as the nutrients are basically chemicals or are there organic nutrients that can be used?

Isn't it kind of important to keep the water level in a DWC system? At about 80%...

How much lettuce do you eat? 😂

Awesome project and love you're stuff. I may sign up for your patreon just to get this print but man... listen to the lyrics of the song before you choose it...

The pups are actually what's used in large-scale pineapple production because they produce a larger, faster pineapple. The pineapple tops also produce pineapples but sometimes smaller than a pup's and take a bit longer. Lots of good info on the video. Thanks.

hy!! I'm from Argentina, could you please make a video with all basic products, with the cientific names an qtys to make the solution? so we can buy 25kg of several bags and make our own!

One thing that I rarely see mentioned in these videos that is SO INCREDIBLY IMPORTANT TO KNOW when it comes to pH is the fact that PH CHANGES WITH TEMPERATURE PEOPLE! I've seen that mistake happen so so many times, that people don't understand why their pH shot up or down randomly. My mate that is because you took it outside and it's fucking hot outside so the temperature went up and the pH went down. That's how that works. That's chemistry for you. When you read that the normal pH of pure water is 7.0 then that is at 25 degrees celcius. At 10 degrees it's 7.27. At 40 degrees it's 6.77. Temperature changes pH.

love the look of the studio !!! Thank you for the knowledge share

Your initial base looked like 4 x 2 inch, potatoes like to grow down before they grow up. I used to grow them in a bale of straw or hay starting at the third biscuit down or wafer. I suppose you could use the hydroponic way of drip feeding through the straw. Just a thought.

Romio that! Great clip... thank you.

For how much time the water can be kept without changing? Plz reply🙏

Does this company have lamps with spectrum control at 1000 watts? And is it possible to control them remotely

I have had blossom end rot on my Kratky tomatoes as well. I think the issue is the plants inability to access the calcium due to the EC. It may be more due to the Kratky method so I am applying tums in a topical spray to address the end rot.

DWC should be kept topped up. I'm not sure how he keeps misunderstanding DWC.

I just finished my neighbors home is looking so good

Organic pesticide, a barn cat. I think rodents avoid onions, but I could be wrong about that.

🤔👍👍

i would say it would be best to also have a second test this with the deep water culture closer to the fan and the kratky away from the fan and see if it is the fan was a factor in the results

You need to get yourself a few cats and let them have the run of your greenhouse ! Rodent problem solved ! 😅😊

Great video. Very much informative

Should've pruned for more fruit.

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????
