Also there is a lot of sand in the coco as well. Coco coir is an increasingly popular type of hydroponic growing medium — and for good reason. The ideal pH for coco coir cannabis nutrient solutions is between 5.8 and 6.0 in vegetation and 6.0 to 6.2 in flowering. For centuries, farmers have used soil to grow a variety of crops, but the technique to grow anything without using soil is definitely new. However, if it is not properly prepared for growing cannabis it can create problems. Coco coir (often referred to simply as “coco”) is the most flexible grow medium. Coconuts, which are produced by coconut palms (Cocos nucifera), consist of husks that surround the nuts. I've ordered some feed and a pH/EC meter and it turns out I now need to buy batteries (doesn't say which kind, very helpful), buffer solutions and distilled water before I can even use the thing. I wouldn't trust the not needing prepped advertisements. So this is my first time growing in Coco coir, that being said I've done the research and it's advised to rinse the coir good! Buffering can work in several ways. The soil can be a good buffer, for moisture and also ions (Ca and Mg) and pH, too. Are there any coco coir products available in grow shops, or do I have to find them myself? Coir peat is a by-product of the husk fibers that are used to fill cushions and car seats. This would mean that there is as much as 1.56g of Potassium per 100g of media. 24,600 Kg Palletized 680 Bales Floor Loaded (25 Kilo Type) 560 Bales Palletized (25 Kilo Type) The high salt and sand content is most likely due to the processing of the coir near saltwater and sandy terrain. Coco Coir is a mostly inert medium, containing cation exchange sites that naturally contain K and Na.These sites will preferentially suck up Ca and Mg, releasing K and Na.Removing the Na and K is known as ‘buffering’. It takes between 4-5 gallons of water to hydrate a 5 kilo block of coco coir. Idk if they mean buffered/charged w npk nutes tho. As a result you obtain coir that meets the the generally accepted quality standards. I'm … Coco coir – termed as the best medium to grow plants, especially cannabis – is not new. It's been buffering for 6 hours in Cal-mag. But there are several processes included in the coco coir treatment and without proper processing of the coco coir; it will create an imbalance in the proposition of calcium and magnesium in the soil. Summary: The best pH for coco coir. Buffer coco peat helps plants to get rid of soil-borne diseases & holds 22% air even when fully saturated available in 650g. Of course that will also need some nutrient supplementation, either synthetic or organic. Washing just means u throw regular water and get rid of excess runoff until i get a low ppm. However bacterial activity and nutrient quality can have an impact on pH stability within the media. I wish this was more clear. How to Prepare and Buffer Coco Coir. Coconuts, which are produced by coconut palms (Cocos nucifera), consist of husks that surround the nuts. Coco coir buffers pH in the range of 5.5 – 7. I always hydrate, rinse and then buffer or "charge" the coco with a 1/4 strength nutes and 10-15 mls of calimagic. So I will just explain a few things first,it seems the general opinion for preparing coco,is to firstly flush to get rid of any salts,tanin and nasties.Then to mix the solution to an ec of around 1.5-1.8,then ph and soak the coco,drain and your good to go! Coco is a miraculous growing medium capable of explosive growth. Coco substrate can act as a buffer, storing water and nutrients for the plant. Potassium is also released and becomes available for the plants. Cation Exchange Capacity (CEC) Coir has a high cation exchange capacity. A nice compromise is using maybe 30% - 70% coco, along with soil. Buffering with a calcium or magnesium base will often displace any excess sodium or potassium levels, balancing the ratios of cations in the media. As nutes are absorbed, hydrogen ions are released, lowering the pH of your coco. Because the texture of the blocks is very firm, you will need to be prepared initially for the water to run across the surface and down the sides of the block. Greetings peeps, I have been doing some research on buffering my coco and will be useing "canna cogre buffering agent". Coir is often sold already buffered by some suppliers, such that it can be used immediately, but the buffering will leach out as well to some extent, and is ideally readded. The nuts are consumed as food and the husks are used to produce various types of coir growing substrates, including chips, chunks and peat. There are water buffers, pH buffers, nutrient buffers and the coco buffer. There are a whole host of benefits to growing with coconut coir that you can and should take advantage of if you’re new to hydroponics. If I understand correctly, what coco/coir means is actually a mix of coco shells and coco fibers. These are the four cations that are most important when buffering coco. Bagged coco should be washed, if not then its a shit company. Alternate the pH of waterings to give a range. This means the media helps to maintain optimum root zone pH (resulting in optimum nutrient uptake). Coir peat is a by-product of the husk fibers that are used to fill cushions and car seats. Coir manufacturers calculate how much they use to get the desired result, and one reason pre-buffered coir has become so popular is because it takes care of … Coco often has a CEC in the range of 90-100 meq/100 g of media. The nuts are consumed as food and the husks are used to produce various types of coir growing substrates, including chips, chunks and peat. The total of these negative charges are collectively referred to as the CEC. Even the manufacturers of most common grow shop soils recommend buffering the substrate with coco coir these days. Washing and Buffering. To Buffer the coir fiber we must introduce divalent Ca+2 and Mg+2 ions to remove natural K+ and Na+ ions present in coir fiber. Took me a 5kilo block to fill 5 , 3 gallon pots. There is a considerable difference between buffering media compared to washing it. Coco coir is made of coconut husks that have been ground up. Okay, I understand all of that. Only wat to know is w a ppm meter and checking runoff. pH Buffering Coco coir buffers at between pH 5.5 and 6.5. The CEC is significant in growing media because it is a measure of the quantity of nutrients the media is able to hold on to before nutrients start leaching out. What are the differences? Hello, About to start my first grow but i'm dead lost on coco. washing and buffering coco coir. Washing coco coir simply removes water soluble components like sodium which has built up over time. We recommend to buffer coco when we are working on 100% coco coir, but you are working on a mix of compost, peat moss and perlite; compost and peat moss will minimize the possible toxic effect of Na excess, We know that the sodium can easily be leached from the material using irrigation. I was wondering how well buffered Canna Coco A & B are. Hydrated Coco Coir should make 12-15L of medium per 1kg of dry, compressed Coco Coir. The CEC of coco is naturally loaded with potassium (K) and sodium (Na), with little or no calcium (Ca) or magnesium (Mg). Nutrients are then released into the solution around fibres in the soil (slow release/equilibrium). Coco as a Unique Medium. That is, coco coir, more so than any other media is extremely forgiving. Washing removes only elements soluble in water, buffering also removes elements which are naturally bound to the cation exchange. After adding 40% perlite. Nutrient buffer. Soil particles and organic matter have negative charges on their surfaces that attract cations. The opposite happens during hours of darkness due to the release of hydroxide ions, which makes your coco … So I have my coco hydrated and buffering right now. GL The nature of “buffering or treating” a coir product is to essentially swing the balance in favour of the calcium & magnesium and against the potassium and sodium. The pH of coco drops (more acid) during hours of nutrient uptake, which is primarily during the hours of light. Then buffer it by adding Calmag. In the last few years, most soil growers have begun blending coco coir into their own homemade super soils. Coco: fibres are already filled with potassium and sodium. Try to keep the coco coir medium at a pH of 5.8-6.2. Growing with Coco Coir — Indoors — in a 4x2ft Tent Friendly Aussie Buds are using 2x5gal (7.5x19L) smart pots. Thats a lot of salt! If the EC of a coco coir medium is over 0.5 mS/cm, buffering may be necessary in order to displace the sodium ions bound to the particles. It's super easy to buffer. Pack Out Per 40' HCB: 27,600 Kg Floor Loaded. Coco coir drains better and keeps the roots oxygenated more than standard peat-based mediums. Coco peat 5kg blocks; Coir sheets 1m x 5m (autumn special offer) Coir yarn large; Coir yarn small; Home / Buffer coco peat / Buffer coco peat 650g Buffer coco peat 650g £ 6.49. Coco Coir's Cation Exchange Capacity. you can buffer with regular water first and then do a final soak in calmag water. It is often sold as compressed bricks for easy shipping and storage. The amount of buffering agent to use will depend on the condition of the starting coir, and the particular agent used. The strategy is to buffer the stuff, with calcium and potassium, as those ions actually replace the sodium (and are nutritionally important as well). I personally use cocotek by general hydroponics. Hello, just a quick question. Naturally, coir is loaded with sodium & potassium and very low in calcium & magnesium. Here you can see one example. Peat/mineral soil: nutrients bind to the fibres or particles using charged sites know as Cation Exchange Sites. Buffered usually means it has calmag i believe since coco needs calmag. Nutrient buffer Discover the other differences by watching our video! Lately, the usage of coco coir has gone up, and so has the demand to produce more coir. Out of stock. Another misconception I have commonly encountered is that by measuring the run off (waste) in coir it is possible to measure the pH of the medium. I suppose I owe you a thanks for pointing out the difference between coco and coco coir - so thanks . Coco coir buffering begins with flushing and rinsing the fibers with clean water. Honestly you can use the cheapest ass block of Coco coir. The Coco Buffer Dose Unit is a precise optimal dosing system, developed together with Veldex and SERCOM, that allows you to save up to 80% of buffer agent, be 100% water efficient and reduce the amount of water used by 30%, compared to traditional buffering method. Among all the treatment processes, the buffering of coco coir is one of the main treatments done on the coco coir. Water to runoff of 10-20%, and monitor the pH of this runoff to catch issues early. Buffering on the other hand reverses the bonds that were made between the media and the salts, releasing the potassium and the sodium. There isn’t a good, comprehensive guide to coconut coir out there… until now. I should have bought pre buffered coco but i honestly didn't know that was even a thing. My question is after I've done that and everything is good to … Made out of coconut shells that would otherwise be thrown away, this unique substance has surprising benefits for cannabis plants. It is in coco and all my nutes are organic. During the buffering process, coco coir cation exchange complex is saturated with a solution of calcium nitrate for an extended period.
