- This video discusses growing potatoes by simple hydroponic and sub-irrigated plastic bag methods. Additional details may be studied from the article "Sub-irrigation Methods for Growing Potatoes in Containers Under a Rainshelter" by B.A. Kratky, M.T. Yamasaki and R.N. Ishizu which was originally presented as a poster paper at an ISHS Symposium in Agidir, Morocco in February, 2006.

Fascinating as always, I appreciate all the details. Trying some method is certainly on my to-do list. Big blue thumbs up.
When looking at the space needed it's probably also important to remember that the people who would grow in bags in a greehouse also probably wouldn't be growing in a field as an alternative but rather in raised beds or grow bags in that same greenhouse requiring the same aisle space.
Excellent video, full of great detail, I enjoyed it. Also, I like the channel name change. Grow Kratky is so much easier for everyone to find, although DakineApproaches was a novel idea.
Based off your ratios found using around 6.1 gallons of nutrient per pound of potatoes harvested, and an average of 7.2 lbs of potatoes from (2) seed potatoes, I am considering a floating raft setup in a 44 gallon container in hopes of replicating your harvest achievements. Aloha!
Thanks, Matt for being so observant to notice that I am changing my channel name. It should have been done long ago, but I always worried that the change might somehow erase all of the videos. Regarding the calculation of potato yield - there would be 5.55 bags (with 2 seed potatoes) per sq m. If the yield was 7.5 kg/sq m, that would be 1.35 kg/bag = about 3 lb/bag. I think it should be possible to double that yield and that is the challenge I give to you and other viewers!
Thank you for your work !
I find this video especially interesting
Nice video presentation 👍!
Thank you for sharing knowledge!
I like the channel name change! I'm not growing potatoes via the hydroponic method, but we are trying the straw on top method... who knew? Answer, not me. They're looking really strong so far. I hope all is well, kind sir.
I wonder if keeping the seed potato submerged for the entire grow duration would help.
I'm guessing they would rot. Give it a try, Jeb.
@@Jewelrymaker If the water has enough oxygen I think they will be ok
Hi Jeb, I think that having a small portion submerged might work, but not the whole potato. However, as you suggest, it might be worth a try if the water is well oxygenated.
@@Jewelrymakerthe seed always rots.
Great video...time to try it. Thanks

8:32 OMG! LOL and coughing!
How did I miss the notification on this!? Thanks for this. I was opining to a friend about how potatoes might fair hydroponically. I don't eat potatoes much at home so I never bother to grow them but I considered growing some specialy ones for special occasions. This is fascinating. Thanks for all the details. Some of it is a bit detail dense, but it helps to know why it works so as to know why something won't or doesn't work.
I want to try to grow ginger and turmeric hydroponically but it's such a odd task it seems as they are root vegetables. and I've only seen Aquaponic or Clay pepple beds done sucessfully, My attempt failed with a watery grave when a rain storm blew in and flooded my bucket of pebbles. I will try again and consider if some of this potato research could be applied to the ginger/turmeric.
You might also look at my youtubes for growing ginger by a pot-in-pot method and by a Larry Hall method
Nice.
Very interesting video. Is there a blueprint available or a more detailed video about the newspaper method anywhere online professor? Greetings from Greece
Sorry, we don't have a blueprint or detailed description available.
@@growkratky5558 thank you for your reply. Guess i will have to learn through trial and error
What are your thoughts on free city or county mulch as the growing medium? Too dense?
One concern is that it might vary from batch to batch depending on the raw materials used to make the mulch.
Considering the 18.9 liter bag method and reusing the growth medium it should lower the cost even more and be the absolute winner, or do I see something wrong?
Yes, if you can reuse the growing medium, then you will only have the initial cost. The problem is that diseases may build up in the growing medium and folks often find it simpler to replace with new medium rather than making such treatments as solarization to the medium.
Greetings Doctor BA. Kratky. I wonder if I can substitute coco peat in the absence of peat-perlite.
Yes, that should work.
Greetings from Córdoba, Argentina. I like your videos a lot, and I have to say that because of them I started a few months ago my firsts experiments in hydroponics following some of your videos (I had good results with lettuce, arugula and pok choi akusay). Now I started a new experiment with beetroots and I like to start one with potatoes. Can you tell me if the nursery tray where the wrapped potatoes were placed was partially submerged in nutrient solution? . If the answer Is yes, how much cm was submerged?. Thanks and congrats for your work!
Thanks Juan. Considering that the tray height is 5 cm, the solution level should be maintained at 3 to 5 cm high, but it might be just a little above the tray at planting time to insure the newspaper becomes moistened. Once roots form, then let the level recede to the 3 to 5 cm setting. I have visited Argentina, but did not visit Cordoba.
@@growkratky5558 Thank you for the information!. Best regards
I have an idea for the potato on soil method. Instead of covering it with straw, would covering it wit perlite work the same?
That might work, but too thin a layer won't achieve exclusion of light which could result in greening of the potatoes.
@@growkratky5558 I forgot about the light, thanks. I'll try fine coco coir on the bottom and coarse coco coir nuggets on top with 1 1/2 inch hydroponic solution. I found a round plastic strainer that fits in a 5 gallon bucket for my pot in a pot, so the soil only touches the water solution around the sides. I will connect 4 buckets to a float valve reservoir.
Sir thank you for the video. I'm currently trying to learn about making nutrient solutions from scratch. Do you know of any good books on the subject or point me in the right direction? Chem Grow seems high and when the price is factored and it makes the cost of growing my food as costly as just going to Walmart.
The scienceinhydroponics.com site has some information on this.
@@growkratky5558 thank you for the response. Lol do you do autographs?
paper potatoes into yukon gold nuggets.. hydro alchemy!
That’s very interesting. I’ve been wondering about this. Would like to see more. I’ve been experimenting with carrots and having best success in cells with coco/perlite. Would be great to see more of how you actually grew the plants. What is the purpose of hilling with grass? How about using a net to catch the potatoes?
I would like to know more about your working with carrots
The hilling is to keep the potatoes that are growing at ground level from turning green. Gardeners traditionally "hilled" (covered the potato stem) with dirt as the stem grew. But you can protect the emerging potatoes with anything to keep them covered so they don't turn green: grass, straw, dirt, compost, etc.
@@margaretd3710 thanks for the info
Would this be similar for sweet potato?
We didn't try sweet potato, but I think it could work.
nice video but wish more hands-on and less data
best
Yeah, I got a little carried away with all the data.
Dr. Kratky. I have developed a system to keep the levels of water stable in a passive hydroponic system. It's basically a "Mariotte bottle". Please Google Mariotte bottle and see what I mean to explain.
Thank you. I had not heard of this concept before. It also has great potential for automatic watering of potted plants using very low head pressure with a low flow button dripper.
@@growkratky5558 I am looking forward to see a video on your RUclips explaining the concept to your students. Farmers can use 55 gallons drums as Marriott bottles and feed tomatoes or peppers planted in 5 gallon buckets.
Oh boy, time to get tinkering!!!
That's the spirit I am looking for!!!
