Making hydroponic solutions
A simple tired and trusted way to make hydroponic solution for growth of a variety of plants. Link to order calcium nitrate, https://campbellteaching.co.uk/calcinit/186/1kg-yara-calcinit-calcium-nitrate-fertilizer-15.5-0-0.
For hydroponic nutrient solutions I make everything up by volume, rather than weight. I add 15 mls of the calcinit (calcium nitrate) to 100 mls of warm water. This dissolves in the water. I then use this as my stock solution. I dilute this 1 part into 250 parts of water to give my final solution.
I then add the same concentration on NPK fertiliser with trace elements. That is, 15mls of NPK fertiliser dissolved in 100 mls of water used as a stock solution, added to the same 250 parts of water I have just added the calcium nitrate to.
I also add magnesium sulphate (Epsom salts). I make the stock solution up with 7.5 mls of epsom salts in 100 mls of water to give the stock solution, this is also added to the same 250 parts of water. Again, one volume of Epsom salts to the same 250 parts of water.
If you like you can mix the stock solutions of Epsom salts and NPK fertiliser. However, it is best not to mix the stock solution containing the calcium nitrate as it can precipitate. When they are all diluted in the 250 parts of water it is diluted enough not to precipitate, and it is fine.
What!? I am so thrilled to see you here Dr. Campbell. I have been following one of your other channels to help walk me through clinical evidence on the you-know-what lol.
I look forward to following you here as well.
Thank you Dr. Campbell! What is the ratio of NPK fertiliser should be? Thanks again.
Omg this is Dr John
Can I use NPK 12 12 36
DR CAMPBELL! so weird to stumble across you this far away from medicine! haha
Master Blend formula for one gallon 600 PPM. Thank you.
Link below no longer works.
Dr Campbell!!! Recognized the voice immediately! Hope you are well!!!
Thank you great video I appreciate it ❤️ 🇺🇸
Sir , how do you decide 15mls in 100 ml water and taking 4mls to make 1000 mls solution B and 15+7.5 mls in 100 ml water and taking 4 mls to to make 1000 mls solution.Is there any calculator or formula. I am new to this and learning to make my own solution at home. Please guide me, it will be quite helpful and will be so thankful. Also how to calculate,select nutrients/fertilizer for grees and flowering and fruiting plants.
15ml in 100ml , so for 4ml will = 15ml / 100= 0.6 so if you scale up to 1000ml will equal to a ratio of 0.6:1000ml or 0.6.ml: 1L. which is 60ml or 4 tbs to every 100L . my system is 400L so it will work out to 16 tbs …
Holy Moly! It’s Doctor Campbell. Truly appreciate you and blown away to see you have this channel as well. Thank you!
Oh my so nice to see you here! I follow you on your other awesome channel!!
are you Dr John Campbell twin brother
I happen to do everything by mass – kitchen scale gets used multiple times of day, just how our household happens to work. I took your recipe and basically assumed that the NPK and Calcium Nitrate are 1:1 by mass, then made sure to use half as much epsom salts. I’ve introduced the nutrient blend to our NFT system today – keeping the EC around 1.0 because I’m waiting for some seedlings to catch up with the strawberry crowns.
Thanks for getting me started – I sincerely appreciate you sharing your knowledge!
So it’s 15ml + 100ml water right..? Not 15 ml + water till 100ml total solution..?🤔
Dr Campbel!
excellent
???
Well how exciting! I’ve been following you over on the Dr. John Campbell channel since the Pando started, and now I’m researching hydroponic methods, and here you are! Awesome!
Bless you, Dr. Campbell.. !!!
Thanks for making this video!
Nice and clear. Thank you
Thanks for this.. helpful for me to make my own hydrosol… how long can you store or keep the master solution if not frequently use? Thanks again.
Thanks for the detailed explanation.
Best explanation and howto ratio on Youtube ever for nutrient. But why ml? why not grams? I thought it was grams as each nutrient volume will have different density.
Hello Dr. Campbell! Glad to see you doing this video! I follow you in your Covid series. Very very informative. So I believe you got all this nutrient solution right! will try it tomorrow 4 June. Keep safe! God bless you!
Wow,
I was shocked to see you there Dr. Campbell. I have been watching your other channel. It is by far the best on that subject. Now I must investigate this channel.
Thanks for all your help.

Oh look its Dr. John Campbell, total sham of coronavirus, he was once a hydroponics expert before pretending to be a doctor (even though he’s a nurse): I wouldn’t trust him to make change for a dollar.
Whoa this is amazing! All of the other hydroponics videos just say – add the nutrients – like its a big secret ! Thank you for such a thorough yet concise explanation! Everything i needed in just a few minutes. Brilliant!
Thanks very kindly, Dr Campbell!! This is simple enough that a person can do this, with things that are easy to find, even when other things are not so easy To find.
You’ll face judgement in your living, feeling flesh – for your treachery and traitory.
If you’re just a sad, lonely sellout – nothing to fear.
Any more insidious than that old son – it’s chop chop either way.
WOW you do hydroponics too!!!
Do you have a book to mix or to make the hydroponic solutions
Thanks for sharing all the details on the hydroponic, great explanation. So appreciate it!
Can this be run though a UV filter without compromising the solution?
Are you John Campbell’s brother?
Appreciate this video. I was shocked to find the great Dr. Campbell when looking up hydroponics.
Is this also John Campbell that does all the awesome covid videos as well?
Thanks Dr. Campbell. I learn so much from you. Best video I’ve seen yet on mixing the solutions. I’m feeling very confident now.
Great vid doc!
1 ml is equl to how many grams?
Would of been quite easier for the general utube audience if you would done it per gallon
Great video, finally someone explaining the rations and why. Not just "yeah I like to add this much for a container with this much yadda yadda yadda".
One question though, why did you add 4ml of both solutions. I was under the impression that A and B make up the stock solution, so you would add 4ml total, not 4ml from A and 4ml from B, which is then 8ml total. Thanks for the video!
May i ask sir. What was the unit used in the glass of water and the spoon?
Going by your descent into COVID grift, I will stick to buying proper nutrients.
There appear to be no videos demonstrating their effectiveness – quelle surprise…
Would this work in a normal green house on tomatoes and salads
Love it. Hope your cannabis turned out lol
Thank you so much. I am going to convert my basement into a hydroponic garden for year round vegies. I live in NE US and my basement is not heating so I have a problem there. I am thinking of investing in those indoor tents to keep the temp regulated. I have to try it out but this summer I am starting it outdoor. This is going to be fun. Thank you for your awesome vid. Most grateful.
I’ve messed around growing with these nutrients but found my way back to organic living soil just like the forest.
