Did you wash the slate before applying?

You jabber way too much!

Where do you get the slate from?

Awesome! Thanks.

Cool facts, thank you for the research and the time taken to make this video! This was well put and interesting to watch. I liked the jokes a lot! Good luck for the thesis and for the channel. This is the kind of subjects i'm interested in! (i'm less interested by potatoes, sadly, haha)

Fantastic. Godspeed, Ettie.

Best of Luck Ettie, on your fascinating thesis topic. I'd no idea about vermin laws & parish church records (or how/where they're located?), having done a lot of genealogy these records could be of immense assistance to trace ones ancestry. We'd feed our local birds, Magpies, Currawongs, Kingfishers, so thanks the tips on keeping them healthy ❤

Good luck, Ettie!!! ❤

Fascinating interview on the subject of human and raptor relationships. I look forward to following Waterman's research! Small correction at 1:35, the bird on the right is a common kestrel rather than a peregrine falcon. Thank you for the video!

Great

Newest sub, will share on social media

I indeed know more about lice and DNA than I did before I watched this video... not sure how this relates to potatoes 😉 Good to see you, kind sir. Peace!

Hi Dominic, very fascinating setup you have here. How you were able to get the initial tubers in this system to produce roots before they were in contact with the water? Did you top-water the media? You also mentioned in a previous video that the stolons need to encounter mechanical resistance from the media in order to begin producing actual potatoes. I've seen another video of a aeroponics farm in India where they grow potatoes. In their case it appears that the potatoes grew completely suspended in the air! I'm wondering how the stolons were stimulated to swell in the absence of any mechanical resistance as there was no media at all in their case. It also makes me wonder if your system would work without a media, if you just instead left a lid to cover the top chamber with a hole to allow the potato leaves to grow. You've probably thought a lot about these sorts of things so if you see this comment let me know what you think!

I'm not sure NFT would work well for taters. I'd try drip irrigation similar to a flood and drain system but without the flooding, just let it drip down into the DWC with the air stone

I don't know a lot about potatoes exccpt they are getting expensive here lol. I didn't know scabbing was from dry soil. That is interesting. You may want to watch Dr. Kratky growing potatoes. He does it in a similar way. Except he puts about a foot of mulch on top. I'm guessing it is to keep the moisture in the growing medium. He does outdoor in Hawaii.

Esh those power guzzling HPS lights will sure effect the bottom line on a commercial application!

I wonder though. Root rot using a Kratky method is usually from overfilling the nutrient solution. It drowns the air roots.

I haven't tried it yet, but I have used grow bags in a shallow pool of water outside (not hydroponic). It does pretty good. So when I try hydroponic potatoes I plan to try some kind of wicking system first.

Good to see you working the spud lab. Peace! Smash.

Dom might have missed it but what variety was I the first trial?

My favorite beginner plant. You don't even have to go to the nursery. A great teachers

Dom I live any learn

cheers for the vid

I know some of these videos are a year or so old now, but I just wanted to saw your content has been extremely helpful! I'm experimenting with growing potatoes in Kentucky, and there's a shocking amount of contradictory information online. Being able to see your hydroponic plants made it so much easier to see how the plants would grow and develop, and what I would need to tweak in order to account for that. I'm growing in very large containers, but the advice I had seen ranged from planting seed potatoes with anywhere from 3" of dirt beneath, to a full 12-20" of soil beneath. From suggesting traditional hilling, potato towers style hilling, to even no hilling at all... Needless to say, it's just been a lot easier to learn about the plant, vs trying to figure out what advice is actually based in fact/science vs what isn't - And your content has been incredible when it comes to learning about the plants! Thank you for making it, and I hope you continue to! :)

Fascinating!!

Good work, Kathryn. 👏

Hilling is a mostly archaic activity but it still has the benefit of cooling down the roots at the bottom. Potatoe roots like it below 67 degrees.

soilless means soilless you can not have half hydro and halve soil and still call it soilless you are still growing in soil for your stolon's remember, you literally refer to the coco peat container as soilless...i find it to be very contradictory and confusing ,Do you know what a rain gutter system is in a way this is basically the same thing as long as the soil can wick up nutrients from the bottom via soil or roots the plant will grow. just one last thing once you planted the seeds do you water them from the top container? what happens to the water draining to the bottom container? do you drain it ? or do you leave it until the roots come trough and then wick it up?

i really don't understand what you are talking about you mentioned they produced 166tons on a hectare ,then you said if they scaled it up so which is it? then soilless means soilless you can not have half hydro and halve soil and still call it soilless you are still growing in soil for your stolon's remember, you literally refer to the coco peat container as soilless...i find it to be very contradictory and confusing ,Do you know what a rain gutter system is in a way this is basically the same thing as long as the soil can wick up nutrients from the bottom via soil or roots the plant will grow. just one last thing once you planted the seeds do you water them from the top container? what happens to the water draining to the bottom container? do you drain it ? or do you leave it until the roots come trough and then wick it up?

very cool thanks for sharing I wanted to ask with regards to the nutrients what did you use and at what grams im intrested in the science of this thanks again

Would hydroton be a better substrate? It can be kept slightly damp without any risk of swamping and as it's a looser medium it won't compact, which fixes the concerns about developing an anoxic environment.

are you still having the potatoes grow in the substrate and just having the roots dangling below the substrate (into the reservoir like a DWC method)?

I`m on disability with no transportation in very rural Louisiana. Gonna try growing potatoes indoors with lights. I just bought six 5 gallon food grade buckets with lids for storing some rice and lentils but I`m thinking of using some for indoor growing. I`m planning to invent a way to grow potatoes in large totes using hydroponic solution for feeding/watering. I was thinking a layer of clay beads in the bottom of a tote with water pumped through it will work if I can shield the developing potatoes from light somehow. I have multiple ideas and nothing but time to figure it out. Your way may be the best but I plan to do some brainstorming. I`ve seen potatoes we had stored under a trailer send out runners to the light and potatoes grew on top of the ground in the dark, so this gave me the idea that maybe they can grow in air if the feeder roots get fed. I bought 6 tabletop hydro gardens for fresh leaf lettuce like butterhead, herbs, and other greens, and they work extremely well. When I heard about a possible fertilizer shortage I bought enough nutrients for over 3000 plants but it was under 100 dollars. But right afterward one type I bought doubled in price. I`m moving into a camper as soon as they get utilities connected and the first project is two indoor yellow squash plants in my buckets using hydroponic solution. I have some nice grow lights.

Hi Dom - great video! A bit late to the party but hey! A few questions. What was your newts that you used? Just veg or mixture of veg and bloom? Was it hydroponic ready made or home made? Also when you planted the OG tuber did you put it right at the bottom of the top tub? I'm interested as to how the roots went down to the newt solution. Thanks mate!

Have you tried the newspaper method that Dr. Kratky has done?

Pretty slick setup. So, if I visit your lab, will you cook me a potato? Smash. Peace!

Dom can you set it up in a chitted Premiere field please they are close to tuber initiation and it really dry at present

You are a pioneer. I can see a cultivation like this on Mars

Good work! Thank you for sharing your adventure with us. Looks like you are getting close to a good method.

Amazing - the quantity and quality of green growth from just the window.

Playing with numbers: Roughly 1450 pounds in less than 500 Square feet! 1450 x 347 Calories/pound is 500k Calories. By 2k personal needs/day is 250 days. Awesome. I'm assuming this was yearly production, correct? I wonder the number of crops and days to production on each crop. Varietals can make a huge difference.

"The Complete Guide to Soilless Gardening", Prentice-Hall, 1940, is one of my recent treasures that I look forward to reading.

We get scab in the ground here. And on my apple trees. I can treat with chemicals (organic when I can ) but those should be fine to eat as scab usually doesn't affect taste(at least here in my garden tests it hasn't lol). They just are not pretty and I cut all the peel/skin off. Oops I forgot what I used its an organic fungicide with mostly sulfur in it.

Hey, air inject the entire thing, keep the tubers fairly wet tthe whole time. You know there is enough water when you see some bubbles on top of the soil. You will have the biggest potatoes you have ever seen and tons of them. Don’t ever drain it, keep it so it’s bubbling on top the whole time, and do the 24 hour photo cycle. Trust me bro, I promise you will have some great content. Massive potatoes. You’re welcome

Lady Rosetta or rock star???

Oh, my friend, no apologies are necessary for "Peace!" By far the most in-depth discussion in chemistry I've heard in... well, ever. Happiest of New Year wishes to you. Smash.

As a present day pig-dad to our pet-pig James-Bacon, this is quite cool stuff to learn about. Dankje Donna!

Counting all leaves, eh? That's dedication. Peace!

Can you share the relative size of containers ? Is this something that you built ? Can you let us know where you got those two containers - the reservoir and the potato growth stack container - from ?

I envy smart folks like y'all ("y'all" is something us yank colonists says). I hopped around and listened to segments... but it looks like you posted the highlights, maybe I'll give those a listen. As always, I appreciate the close. Peace! 😁
