Auto watering Kratky Hydroponic Tanks to Grow Multi cuttings of 'Adagio' Arugula

- Multiple cutting or 'cut and come again' arugula (cultivar 'Adagio') grown by the Kratky hydroponic method requires more nutrient solution than the initial tank capacity. A storage tank-float valve system supplied additional nutrient solution after the liquid level had dropped to about 2 inches and this level was automatically maintained throughout the remainder of the crop.
Five harvests of arugula were taken during a 92-day growing period in Hilo, Hawaii.
The correct technique for cutting arugula to encourage regrowth is suggested.
Single harvest 'Adagio arugula was discussed in a previous youtube • Growing 'Adagio' Aru...
The yogurt container float valve was described in • A Yogurt Container Flo...
The water level indicator was discussed in • Water Level Indicators...
A good idea that I will take note for my lettuces and spinachs. A half crop of each one. Greetings from Spain.
Thank you for listing out how to make the stock solutions. This will save lots of time mixing new batches all the time.
Always love your float valves
It would be interesting to see the behavior difference between the slow bolt variety and a regular variety. I suspect additional resistance to stress is provided by the consistent water temperature, nutrient strength, and water level.
Very good reasoning, Jeb! That is a good suggestion to compare the 2 types of varieties and this probably should be done both in soil and hydroponics.
Very worthwhile experiment, I am looking for good cut and come again plant varieties. Your use of measurements of both time and weight are helpful, and I enjoy seeing your approach. Will be nice to see more videos from you, as your content is interesting.
Thanks, Matt! 'Cut and come again' varieties are an excellent approach and will need to be grown with an auto-watering system and I'm sure you have some good ideas on this.
your information had been very helpful, thank you
What a great diy system!!!💪🏻🌱🙏
You have made many videos on this system, but nobody, including me, have ever tried to make it. Explanations are confusing. It's like giving a course. People outside are very numerous and would love to do auto watering if the video was more synthetic, easy to imitate. Thanks 🙏🏻
I made this. My tomatoes are currently growing in a self watering reservoir with the same nutrient solution. Love it.
👌 Amazing skills
Dr. Kratky, thanks again to share videos. May I ask how to grow bell pepper?
You're amazing, you've inspired me to grow in the past. I was wondering, do you grow trees? I'm kind of obsessed with the idea of growing trees for the rest of my life and was wondering if you had any tips on what species to grow, methods of growing, ect. Thank you again, your professionalism and dedication to growing is truly awesome.
I am not familiar enough about trees to provide any advice. Some universities have forest extension specialists and you might approach them.
A month late but.. You can look into moringa trees. They are a super food, all the nutrients your body needs. I'm obsessed with wanting to grow them. All kinds of videos on how to. Moringa blessings 👋
@@yahnac4201 I agree, Moringa is looking so positive and beneficial to expose people to now.
Very Nice. Of course, I would not trust this indoors ;-) Some of us live in N. Latitudes. But I would be interesting to know what kind of tanks or trays you are using.I would also have to say, you do not report your water temp, your PH, your PPH to any great degree, so I don't feel I have enough information to completely grow by your techniques, since as I lived in CA for a long time, the growing was optimal, I did not have to worry about so many things there, that I do now in other parts of the world?
Some wont' have tap water that works out of the box. It's important to understand why. Or they will have very arid env, so they have more evap issues, have to watch water levels much more, or they have so much evap, their PPM/PH drifts up too high too fast to harvest. I would say, warn people they may not have as ideal env as you do ;-)
also sweet Jesus that's the biggest Arugula i've ever seen :O
We have 100 gram bags in the supermarket (Holland)
Leaves are so small !
But i think that is also part of the charm of the crop maybe
Is this variety bigger than standard arugula or is your method increasing the yield by this proportion?
For such a young crop it is MAMMOTH ARUGULA
You are going to solve the worlds problems. No more poverty.
That's funny.. my arugula bolted and some of it got to nearly 6 foot tall! 😮😅😮. All I can ever find in the store is baby arugula.
I wonder about a small scale indoor set up? Living in zone 5 (brrrrr) I could benefit from a few plants indoors...I have various grow lights to give daily lighting
Are these seedlings placed in with the container completely full. Meaning theh are completely submerged until they consume the water up to the float valve depth?
When the seedlings are placed in the containers, ideally the bottom 1/2 inch of the net pots are submerged and that means the tank is nearly full - not completely full.
Hola Dr, veo que usa una Ce de 1.5 . Este valor varia según la época del año ya sea verano o invierno?? De ser así cuánto en cada época ? Desde ya muchas gracias.
Dr. Kratky, thank you again for sharing. I always love learning about your hydroponic techniques and am looking forward to trying myself for the first time this year with four varieties of super hot peppers (peach reaper, bubblegum habanero, charleston and scotch bonnet peppers.) With my current equipment, I have no precise way to measure the nutrients (other than pH and TDS). For the best growth, would you recommend changing the nutrient solution monthly, or should I change the solution more or less frequently?
Anyway, if you don't mind, I also wanted to ask you about these nutrient solutions and automation. As we all know, the nutrient concentrations will decrease as plant growth progresses. Is it possible to measure individual concentrations with electronic sensors? If so, I am very interested in designing a system with such sensors that provides feedback to a set of three (or more?) peristaltic pumps to premixed solutions to provide nitrogen, phosphorous and potassium for optimal growth. Essentially, I want to create a gardening system that would let any kind of person (even those with the brownest of thumbs) to grow any hydroponic ready fruits or vegetables. That all said, I highly doubt this is possible in such a simple manner, but I am interested in what you might know on this topic. Thanks for your time and looking forward to your next videos!
Dr. Bruce Bugbee of Utah State Univ. has conducted research which demonstrates different uptake rates of the various nutrients. This information could help to shape the approach to your project. I don't change my nutrient solutions for the entire crop and am not sure how much, if any, it impacts yields for non-circulating systems. Good luck on your pepper project.
Aloha! Will your loyal viewers be given an option to buy some of those seeds soon? 92 days and no bolting is impressive.
Adagio arugula is carried by Golden Acre Garden, but I noticed they are currently out of stock. There also was a listing on ebay to sell Adagio arugula seed.
I am planning a similar float valve controlled system but for peppers, and want to know where I should set the water level.. I am using individual 9 inch deep, two gallon containers at this time for each plant. I am thinking that water level at about 6 inches deep should leave enough air space but haven't found much about water depth vs airspace, and whether some plants need more or less air space, and don't know if having the roots hanging too far before they reach water could somehow stress the roots. Is there a general minimum air space needed? Is more airspace than the minimum beneficial?
My inclination would be to set the water level somewhere between 1/3 and 1/2 of the depth, thus allowing 1/2 to 2/3 of the volume for air space. I have observed healthy cucumbers growing in an almost empty 32 gal trash barrel (over 2 ft of air space), but wouldn't expect lettuce to grow under those conditions. Thus, there is a differing range of tolerable air space for different crops. I don't have good data for specific crops.
How do we seal those tubes to prevent leaks? Newbie here ☺️
Nice and cheap system§ why not to replace nutrients by fishes ? So you've got some proteins to eat with arugula ; )
I have never used a float valve before - what determines when the water is filled or shut off? Is it dependent on the level at which the float valve is set in relation to the grow tanks? tY
Hopefully, this will answer your question - th-cam.com/video/pje-yifjeVE/w-d-xo.html
how manny gal of water fits in those grow containers
?
Will this work in the central valley CA temps over 100
As a general rule, I find that most plants struggle at temperatures over 95F, so I would wait for a cooler season.
Dr Kratky
i have a have grow in this and other style systems and have never used iron chelate. i know there are various types of iron chelate available in powder and liquid form and a a few dont really say use except sprinkle a set amount for 1000 or 1600 sq ft . Labeling on a few even vary in percentage some 6% some 10 % and one i saw locally that actually states 10% with an analysis of 3% soluable nitrogen 1% potash 10% iron ( chelated iron ). i do know from testing of my water it is very low for trace iron and has a higher carbonate then some areas at around 80 mg/l and a hardness of 50 mg/l and test for iron showed basically 0. ph out of tap 6.5 - 6.6
My issue is should i use some iron chelate i've never been clear if it would be of any real need for it here and if so what dosages as a guide line i also assume its use will change the Ph - i use 4-18-36 fertilizer ( master blend ) - calcium nitrate 15.5 N 19 soluable calcium - epsom salt ( 8 oz - 6 0z - 4 oz ) per 100 gallon. Would you have any suggestion of brand or percentage to work with.
And on a side note i had seen information on this variety of arugula a number of years ago but have never seen it on the sale here and have have not seen it on some dealers list i buy seeds from. i grown indoors year round and outside in covered area when weather permits. i'd be interested in trying that variety
The Masterblend should have enough iron, but if you wanted to add more, use a rate equivalent up to 1ppm based on the total growing solution which would only be about 20 grams of active ingredient iron in 25 gal of stock solution and you might use a chelated iron source available from a hydroponic supplier. In my case, there was some iron chelate that I wanted to 'use up' and I didn't actually conduct an experiment on any change in yield or quality, but was happy with the performance.
You might contact Dr. Jules Janick of Purdue University, Dept. of Horticulture to inquire about the current suppliers of 'Adagio' arugula.
@@growkratky5558 during this lock down and social distancing for a while getting produce has been terrible for many and i have been sharing with nearby friends and neighbors as i cut and harvest my arugula , lettuce, tomatoes , peppers and numerous herbs i grow. My total variety of plants i grow number in total 25 different varieties of these. I had grown many years ago and stepped away for a bit because the available products at the time and light systems available we few and far between. Now with Led technology the cost and ability to duplicate a good light source at a reasonable cost has made a huge difference of growing year round indoors even in New England area in winter. As i do maintenance of some of my stuff i will do a couple test with the iron and see if i notice any discernible increase in yield - take up of nutrients - or visible appearance to the plants.
Numerous neighbors and friends have been so impressed they now grow some greens and herbs for themselves using this system. Current i am designing and working on my own led light system to test sometime in the near future.
Can I visit your hydro farm?
Sorry, but I no longer have a hydroponic farm and have retired from the University, so I don't have access to their research facilities.
sir are there any alternatives to chem grow?
Yes, there are numerous hydroponic fertilizers. But make sure you use a hydroponic fertilizer rather than a field fertilizer.
