A Beginners Guide: Hydroponic Nutrients
Ғылым және технология
Nutrient management is the crux of a healthy hydroponic system. (Read the article: university.upstartfarmers.com... )
For even more information about Hydroponic Nutrients, enroll in our Upstart University program and check out our Hydroponics Nutrients & Fertilizers course at university.upstartfarmers.com...
Great nutrient management occurs when growers are:
1) Aware of all necessary plant nutrients and where they come from
2) Supplying adequate nutrients in correct ratios to plants
3) Monitoring and measuring how much of each plant nutrient is available in their system at any given time
4) Making economic and work-flow conscious decisions about how to source and supply nutrients.
Most plants (and all of the crop plants that you’re likely to grow) rely on 16 nutrients to grow and reproduce. Of these, three are available through water uptake and gas exchange (the air): Carbon through CO2, hydrogen, and oxygen.
The remaining thirteen nutrients are the mineral nutrients delivered to plants through nutrient solutions (dissolved fertilizer).
The overall nutrient level in a solution is measured in EC, or electrical conductivity.The units used to measure EC are ppm or mS/cm, although ppm is used more commonly for measuring total dissolved solids. That’s a different measurement for a different blog post. Hydroponics really need to understand the second unit, mS/cm. This is often just expressed as the “EC level”. (For example, “The EC of the solution is 1.8,” with no unit.)
Ideal mS/cm is typically between 1.2 and 3.3. There’s a broad range of acceptable EC levels, and each crop has an ideal range.
Supplying the correct ratio of nutrients in adequate levels is only half of the nutrient management picture; the other task for farm managers is to keep those nutrients available to plants, and the main factor influencing that availability is pH.
Nutrients are soluble at different pH values. Check out an absorption chart (there's one in the article version of this video) to learn more.
Adjusting pH to your ideal range can be done with pH Down or pH Up, which are acids or bases (respectively). Never add both at once!
There are two main forms of fertilizer: dry and liquid.
Dry fertilizer is mostly used in commercial settings because there’s a lot less to ship (you’re not shipping water), making it more cost effective. You can also tailor dry fertilizer better to your needs, because it comes in separate parts.
Liquid fertilizer is simple to use and great for home and hobby systems. It’s easier to manage since you can just add a certain amount of one liquid to your system water, but it’s more expensive to ship. (Most people on a small scale only buy a little at a time though, so shipping is less important.)
The best way to mix a solution is to follow the manufacturer’s instructions.
If you’re not using an auto-doser, you’ll still mix it the same way, but you’ll add it to your system bit by bit in equal ratios and test it until it’s at the right level. You’ll get better and better at this over time.
There are a multitude of handheld measuring devices and testers. Our favorite suppliers are Blue Lab, Hanna Instruments, and AutoGrow. We’ve used each of these and are currently using AutoGrow’s NutriTest, a handheld meter which measures both EC and pH with the same device. There are a variety of options out there.

If only all KZread videos were like this. No fluff, no flair, organized presentation, appropriately touched on every relevant topic, and provided additional resources and references.
I watched at least a dozen videos dancing around this topic before watching yours. Very simple, very clear. You have a great way of explaining things. Thank you!

hey ,if anyone else trying to find out aquaponics book try Aqua Recovery Tactics (aqua.RecoveryTactics.com ) ? Ive heard some pretty good things about it and my colleague got amazing results with it.
This is a really informative video for budding Hydroponic farmers! Simple, Brief and to the point! Thank you for putting up such content!
This gave me so much clarity about hydroponic nutrients! Thank you!!
I am voting with the person below. After watching about 50 videos you are absolutely the best at no Blabalblablablablablabla before saying a few useful things. Your video was clear, got right to the point, full of great information. Keep up this great work.
THANK YOU SO MUCH! Im a beginner. Was truly spending time SEARCHING for anyone offering reliable information on exactly what you covered! Your explanations are easy for me to understand and I am very grateful!

But d***, this is so incredibly informative. It felt like I was in a collegiate class. Very nice video. New subscriber here! 😃
As I start my journey into hydroponics I am cursing my high school guidance counselor for discouraging me to register for chemistry & physics. Fortunately I stumbled into a career that has been fruitful but I felt that I was missing something my whole life because I did not have the proper education in these areas. I couldn't tell you the purpose of nitrogen, phosphorous or potassium until I watched your video.... thank you for the education!!
Hi ZipGrow. I'm really surprised to see you still at it. Had heard you sold up and moved on for big bucks. You earned the right to big bucks but glad to see you're still putting out content since you're perhaps the biggest contributor to this kind of hydroponic information necessary to successfully make it work. So nice one brother. Hope the lockdown hasn't adversely effected you all. Hope to see more of your videos sir. Kind regards from Ireland.
Really happy to come across your channel! Lots of information for beginners! Just amazing!
How can i find the specific formulas for specific crops and can you please give more detail about micro solutions? Thanks.
Excellent breakdown on nutrient solutions and understanding what your meter readings are saying.
The majority of technical videos on hydroponics are poorly put together, full or errors, and missing critical information. Your video is thought out and each topic is explained in great detail. Excellent production. Look forward to other videos from you.
You present the info in very ez way to take in, tyvm m8
This is extremely thorough. Great stuff

Very informative and well-done from the way the information was laid out to your speaking speed. Thank you.
Greatly informative in an understandable form. Thanks guys
Great stuff and heaps of notes taken .. thanks
Wow so detailed and yet easy to understand ! Kudos
This is so incredible...innovative minds matters these days
Hi, I am bigger in this field and trying to use my 2400 ft plot for hydroponic set up. i was going through your vedio was reallly useful. thank you,
First hydroponics nutrient video I have watched. Thank you. Very informative video. Every other video I watch will be judged against this. I doubt I'll find better.
thank you for your clear explanation really interesting
very nicely done! Just starting don't have a clue. Now I'm a little smarter. Thanks
So helpful and professional. Thank you

glad you have at least some knowledge of chemistry when talking about this. I have run into some very funny statements where chem and gardening intersect. very informational thanks
Great break down thank you!
Thank you so much for this. Anyone can tell me how, but thank you for telling me why! I am on my second grow and followed a guide strictly. Now for my second I truly want to know why we use these nutrients and how to begin to identify when one is needed. Thank you again!!!
9:17 Actually if you combine an acid and a base they will create something called a buffer solution which will make changing the pH n either direction a lot more difficult. Especially if you use the corresponding base to the acid.
Getting ready to purchase setup by Friday.
Brilliant video, keep it up.
This is the best video ever.... thanks.
Great video!!!
Fantastic video! Thank you. Just getting into hydroponics and found this really informative. Can I get your thoughts on mixing the nutrients ... would it work if I mix the calcium nitrate in warm water first, let it cool down, then add the NPK + magnesium sulphate directly to the same bucket?
You guys have an awesome content, thank you so much.
Thanks you have make it very simple for me to understand. Well done

Great video! I'm trying to grow a citrus plant (oranges), which nutrients ratio should I start? Would it be okay if i start with a higher N ratio, and then switch to a higher PK after its has a significant leafs growth?
Very cool and useful info. Well spoken. Thank you

Great video ! Thank you ! I have a question How important do you think is the origin of those Elements (1,2,3), can they be harmful for the consumer if acquired from the wrong source? What are the guidelines to access those elements. One more question, in your opinion how important/different it is to grow vertical farming in pvc tubes or tube that are made from natural material i.e. wooden ? Great job Thank you
Great Information, thank you very much.
Excellent! Thank you.

Excellent and very helpful video, Thank You! You have a knack for putting this fairly complex chemistry into everyday terms so it's very easy to follow. As another poster commented, feels like a college class where the passionate Professor (you) really knows and loves what they are teaching, For that, thank you ... feed me more. :-) Keep doin' what you're doin', you are helping others!
good job i loved the explanation
I have a 2 part system where I can run the hydroponic unit separate from the aquaculture unit. Can I mix used hydro water with water to the aquaculture, and if so what EC would be the maximum the fish can handle?
Really good info 💯
I’d love to see more videos.
hi, how to produce hydroponic fertilizer for home growing. can i use asimple program like as maxigro for all of plants? from where i can find hydroponic formula
Excellent content and presentation.
Great explanation. Well done video.

Nice explaination , i definitely get dry mix fertilizer and go thru the few extra added steps if I was getting much more fertilizer to uses and it was cheaper because fertilizer gets price if it's a liquid based one. Also I knew how to use the EC testers , TDS testers , and pH testers but didn't know there was equipment like auto dosers that just automatically told you that info on computer screen in real time. So if you did mess up for example pH you could uses a pH up or pH down solution to fix it. And just look back at the auto dosers screen.
GREAT EFFORT TO EDUCATE ,THANKS ,PAKISTAN
Thank you, you guys rock and have a way of explaining that makes me care about pH. I couldn't understand why both up and down, can't you just adjust with water? I should watch the rest of video..lol
hi i need to ask you a question but first great video put everything plain and simple and my question is about something you said on the video about automatic fertilization what kind of machine or gadget do you recommend for cherry tomatoes on a hydroponic greenhouse second question what height do you recommend for a greenhouse if i am planting undetermined tomatoes on the tropic at sea level ? my greenhouse will be 6' walls 18' at the center of the greenhouse 24' wide by 120' long -
Is it possible to test the ec of your runoff to tell when you should add fertilizers? At the start of my grow I didnt have a ph or ec meter, I do now and have flushed and balanced the ph and ec of the plants and the water/ferts. I dont want to start overadding anything again and the rule of thumb ive heard is once a week with ferts and just water the rest. However i am using coco so im doing calmag and azos with the water
so thankful for your work and especially informative videos you do on plant science like these!

If I mix my three food solutions following the label dosing level on a new tank of hydro water - then do I still need to check ec -or the hydro water should be put me at least initially within the correct pH range?
Thanks a lot. very helpful video.
FINALLY someone who can explain this topic who isn't stoned or simply parroting what all the other youtubers said in their sponsored videos.
Thanks. Very important information.

excellent explanation I liked it
Hello , first of all - big thanks for doing this.. you really really helpful. Could you please help me resolve my few doubts.. If I'm growing tomatoes in cocopeat medium, should i be circulating nutrient solution every day three times ? Wouldn't over fertilize and wilt? Or should i be feeding nutrient solution once or twice a week and feed rest of the time water?? I'm doing soilless tomato growing in cocopeat and im afraid of over fertilizing ? Pls help since its hydroponics method nutrient water feeding 3 times a day makes sense but will it cause over fertilizing? Many thanks in advance..
thank you this information help me lots

that you describe part A , part b and Part C solution. where can i get theses all three categorized dry solutions . did i ll get with alphabetical names or chemical names wise. please reply thanks. nice video
I have just ph, my 20ltr buckets and onoe is below 5.5 and I don't have a ph up any advice cheers

Where can I get the crop production guide from
I want to grow lettuce in my hydroponic,can I use common fertilizer for it?,if yes how can I mix it in to right ratios and do you think the crop will grow well using the common fertilizer?and What crop can you advice for this?
Very informational
When you explained about mixing the dry fertilisers you said that part A should be mixed in 5 gallons of water and so also part B but you did not clarify whether part C should also be mixed in an additional quantity of 5 gallons or it is to be mixed in the same quantity of water as part A. So do we land up with a total of 10 litres or 15 litres.
