Happy Hydroponicing!
When you want to cite an academic paper, it would be valuable to provide your viewers a link to that paper, since you didn’t mention use of Magnesium, which almost every site on the Internet that talks about coco buffering mentions.
Awesome! Trying to buy calcium nitrate, but found calcium nitrogen, are they the same?
Wouldnt dolomite be a far cheaper way of achieving this, rather than adding calcium nitrate? If you are just going to rinse it all out at the end anyway.
for those without talent or printing equipment, are your caps and plastic pieces available for sale?
If using the coir to build potting mix (not hydroponics) is the buffering still advised? Seems like it would bc those plants need calcium just as much as in hydroponics.
Not dry for me, an excellent video that answers everything you want to know around the coco growing media.
it explains why a lot of hydroponic setups fail…good work!
Can you reuse the calcium nitrate soup after using to buffer another batch of coco coir?
I’m a bit new to this buffering myself stuff as I’ve always bought buffered coco coir, I’ve got plenty of calcium nitrate so that’s no problem but why am I seeing other video’s adding magnesium nitrate?
do you have a link to the report of calcium nitrate on coco??
Damn no wonder why I can’t find any more of that coco peat from Bunnings you have been buying all the stock.
Hi , is the 5.5 kilograms of coco wet or dry ?
stop. its NOT environmentally friendly. that lie needs to stop being told. the amount of water involved in refining the coir is very damaging. from what i gathered it COULD be environmentally friendly ONLY IF it was only used LOCALLY. its rarely used locally though, infact its shipped all over the world which is the exact opposite of being used locally.
its fine to use it, but do NOT pretend its environmentally friendly.
Kiss method. Good advice. TY
I bought hydro coco but still got BER. How can I rejuvenate last years used Coco please mate?
Your channel is without a doubt the best hydroponics channel I’ve seen on youtube. Very accurate and scientific information, going deep on the fundamental, as well as a lot of hand-on practical approaches. Keep up the great work.
You could almost say you’re in love with the coco 😁😉
I assume this may be the reason Miracle Gro potting soil killed all my vegetables. In fact, most potting soils appear to be a horrible waste of money so far, and when I find a brand that works suddenly they change it. But thank you. This prevented me from buying a brick of this garbage.
Great stuff, you should do a video on the various options of medium that are ok to good to use for hydroponics.
As awesome as coco peat is I don’t think you can call coco peat environmentally friendly, as the amount of resources used in washing out all the salt and processing it is intense! Also working conditions in the places that process it look absolutely terrible and must be taking a toll on the workers health (notice that the workers in the video are not even wearing masks and are probably breathing in a lifetime of coco dust particles every single day. Doesn’t really seem like a very ethical product, I think thats a lie we tell ourselves to justify buying such an amazing media.
No hate towards your advice here, its amazing advice, but these days coco has almost tripled in price and I’d rather look at cheaper and more sustainable alternatives.
In Malaysia, our fertigation farmers are doing this. We’re using CaN and MgS with 2:1 ratio.
2 kg CaN and 1 kg MgS mix in 600 gallon of water. Then dripped into cocopeat about 2L/H.
Every start of the planting season and once a month we drip it.
Hey Hoocho where does the K+ and Na+ go , I guess its just floating around in solution? Can we use that solution anywhere? Thanks for your channel it has given me a wonderful productive new hobby and new personal energy, keep up the great work. The fact you use evidence based peer reviewed studies gives the Channel and your work credibility and a professional status.
Anyone have a link to the paper hoocho cites?
The incredibly high cost of such a ready resource is why I don’t use coco coir. It is way overpriced, and it is imported.
And it is harvested to the detriment of local environments, although recovered from monocultures already created. Monocultures, as we know are bad. Not going to help them.
Pine needles are far superior to coco coir, so a bonus. And, there is plenty of it, without hurting local ecosystems…it literally is laying on the ground and left over from logging.
No way PEAT is renewable, and getting scare due to over harvesting by home gardeners. You should try a product called GLEE. Made in the USA, which is likely 90% of your audience.
Love your channel. I reengineer most of what you show, as you do have great ideas. Keep them coming.
Sir just one question after appling calcium nitrate and keep it for 36 hours then we must wash cocopeat with RO water…
Thank you for the explanation. The Coco Bricks i bought were totally insane. EC of 5500. Salty af…
Is this Buffer Solution for Bricks or for Coco Peat that´s loose in a Bag ? I think Coco Peat from a Bag isn´t completely dry and has more weight than the Bricks that are dry as dust. PS: Great Channel 😎 Greetings from Switzerland.
based on the paper you have mentioned, untreated coco has about 33, 14 and 3.5 cmol/kg K, Na and Ca respectively which are about 50 meq/100g coco altogether. I’ve heard before that CEC of coco is 50-100 meq/100g depending on the source. So the rest 0-50 meq/100g is of other cations. The recommended calcium nitrate is 100g/1.5kg coco which is about 80 meq/100g coco. Using this data and that ~70 and ~90% reduction in K and Na after buffering, the CEC of the sample can be modeled and calculated.
numbers are logical "if" that 100g calcium nitrate is anhydrous not tetrahydrated. so which one? anhydrous? I ask this because tetrauhydrated is more commonly available that anhydrous?
We had a bad batch of the pinegro ‘pre buffered’ stuff that had some crazy high EC run off .. something to be cautious of
I bought a block of ‘unwashed’ coco years ago.. The main issue was it contained a high amount salt 1200ppm. One of the occupations of islanders is to find coconuts floating on the sea to earn a living, so that’s probably how the salt came to be there. The plants had burning, no matter what i did, so I always get the pre-buffered/washed coco for seedlings now.
Pre-buffering of clay pebbles is sometimes necessary too, as they can be extremely alkaline. My technique is to add 10mls concentrate of H2SO4 or HCl to 6 litres of water to 5kg of pebbles in a 10L bucket and let them soak 4 days. Then tip out the buffer and replace it with tap water for 24 hours. Works a treat and never get any PH drifting after that.
I thought the whole idea with hydroponics was soil less media and used a form of block to hold the plant and then just water, could you not use grass clippings or staw or Hay, or am I just looking at the wrong idea.
Hey man. Great explanation. Thanks very much. Threw a sub your way for the effort. Cheers.
Ahh the Bunnings bucket… I’ve heard the tales of this bucket and its glorious aura but am yet to bask in it myself, you truly are a man of culture. (also really enjoying your channel mate, got me from absolute beginner to slightly less of a beginner so far and will continue watching every vid <3).
LOL the start… Sorry … Great information here. I didn’t even realize that you needed to do anything to the coco. Thanks for sharing this info with us.
Do you need to buffer coconut coir if you’re going to mix it with compost and organic fertilizers? Like for outdoor gardening and container gardening?
your video was recommended by Ai
100g CalN per 1.5 kg seems a bit too much… I would not call this process environmentally friendly at all. from now on I’d rather use perlite.
"sorry about that"
Top notch Chad.
Keep on! Your channel is much more useful then what they’re doing with their coco in their moms basement. 🍻
Thanks for this information. It may explain why I have been having such a hard time growing things in Coco coir. It would be helpful if you could include a link to the paper you referenced.
5.5kg coco coir
55L water
350g Calcium Nitrate dissolved in what looks like about 5L hot water.
mix well
36 hours, drain the solution and now use the coir for seedlings.
Thank you Hoocho!
Thanks for this video. You’ve mentioned "hydro-grade coco" often but I didn’t have access to it. Now I know what to do. Thanks again! (Utah, USA)
How often should I change the coco if I’m growing strawberry
were are you? just to give me an idea of your area compared to mine, thanks mate and you have a great new year
I play this at 1.75x speed. When you go back to regular speed it seems in slow motion. He talks very slowly.
Run a drain to waste system and never worry about buffering or lockout issues
hi sir…i have a doubt
Why your not using magnesium nitrate with calcium nitrate for buffering?
Is there any cons for not using magnesium nitrate?
Washing with hard water should do the job without additives. It’s calcium and magnesium ions that make water hard. Any deep well or spring water from a limestone aquifer will be hard water.
Hoocho, if you have to rehydrate a brick of compressed CoCo, do you use plain water or can we hydrate with the CN solution. TIA.
"sorry about that"😂😂😂
@hoocho What are the best best hydroponic solution that you can buy in Australia?
Just a heads up, it’s pronounced coir, not cior…
