Naturally, coir is loaded with sodium & potassium and very low in calcium & magnesium. Washing and Buffering. Optional: Add Gecko Grow 50/50 Perlite and Vermiculite Mix in a 1:1 ratio. Coco coir, in its unprocessed form, tends to be high in both sodium and potassium compared to sphagnum peat. Buffering is a time-consuming process and it starts with proper flushing and rinsing of the coir with clean water. Coco coir naturally can be very salty, as it contains a lot of sodium ions that cling to the coco coir like a magnet. After the water washing process is completed, the coir is thoroughly rinsed with a calcium nitrate solution for an extended period of time. Coco coir is the go-to worm bedding among vermicomposters (next to shredded cardboard). Doublethumb. nitrogen can be supplied as a anion such as calcium nitrate or a cation such as nitrogen sulphate. When coir dust (coco peat) first appeared in the early 1990s, the largest stockpiles were the first to be exploited and these were the oldest. after that you simply just scoop out your coco and rinse off the salt. It can be done in lots of 25, 50, 75, 100, 125 or 150 cubic meters at a time depending on the size of your wash bay. Buffering is the process that also removes elements naturally bound to the cation exchange complex. (BaCl test) Moisture Content when packed 18%. 1 - 6 - 4. Drain and it is ready to be mixed with perlite. 710 Veg. Now add the 0.5 oz (or 14 grams) of calcium nitrate and stir again. BUFFERED-CHARGED it'll save your a bunch of water that way. California Substrates Coco. Coco: fibres are already filled with potassium and sodium. The washing and buffering process we use involves involves several steps. The recommended buffering ratio is 200 litres of treated water (i.e. The processing of coco husks to obtain coco coir involves a series of steps including aging, washing, rinsing, buffering, drying, grinding, grading, and compressing. The absorbed calcium displaces the residual potassium and sodium in the complex, which are washed away leaving a very clean coco coir your plants will love! The electrical conductivity, potassium and phosphorus concentrations in coconut coir increased 2.3, 4 and 17 times, respectively compared with those in the nutrient culture solution, while the calcium concentration decreased by one-fifth in the We know that the sodium can easily be leached from the material using irrigation. Proper processing of coir to lower its natural high salts level should eliminate the need to buffer it with calcium nitrate. Coir has become a major component of both greenhouse vegetable and container crop production. Welcome to. 2) The coco must be rinsed to remove the fine particles of dust; you can do this by using a strainer. House & Garden Coco. It is then pre-treated with a calcium fertilizer such as calcium nitrate to enhance the potassium-calcium exchange. Really important for your nutrient uptake, your cation exchange for your plants to be able to uptake that nutrients. Hmm, again. This topic has 1 reply Posts. Cocopeat, a by-product of the coconut (Cocos nucifera L.), is an important soilless media that contains high potassium (K), sodium (Na), and electrical conductivity (EC) depending on its source.

Then you buffer with your solution for a specific duration of time. Although buffering is not required, if you wish to buffer your coco coir, simply rinse it with a calcium nitrate solution. per gallon. During the buffering process, coco coir cation exchange complex is saturated with a solution of calcium nitrate for an extended period. Buffered Coir Peat and Coir Chip after treatment with Calcium Nitrate, Calcium Magnesium, Calcium Sulfate or any other chemical based nutrient will not be classified as Organic. This product goes through a "buffering" process that involves soaking the washed coir in a calcium nitrate solution before flushing again with fresh water. Heres our buffer formula used to pre-treat and hydrate compressed coir blocks. Cocopeat, a by-product of the coconut (Cocos nucifera L.), is an important soilless media that contains high potassium (K), sodium (Na), and electrical conductivity (EC) depending on its source. Easy to use; Clean, bio-available macro nutrition source; Coco buffer- Buffer new coco coir with 2000-4000 ppm of Base- 1 tbs per gallon. the coco floats to the top and the peat and impurities sink to the bottom. Doublethumb Growing Solutions is a distributor of Botanicoir, Ltd., and Medicoir coir fiber and coco coir products for the U.S. market. These growers are thinking that the cation exchange sites are loaded with potassium and sodium ions and if the coir isnt buffered with calcium nitrate then their crops may suffer a calcium or magnesium deficiency, he said. Coco coir intended for growing plants is usually washed then buffered with calcium nitrate and magnesium nitrate. The recommended buffering ratio is: 1,000 litres of water mixed with 7 kg of Calcium Nitrate will buffer 5 Cubic Meters of coco peat. Finally, after the resting period is over, once again wash or rinse off the Coco coir with clean water. Coco contains a lot of natural salts. The absorbed calcium displaces the residual potassium and sodium in the complex, which is washed away. Additional Uses: reptile bedding; potting mix; soil amendment; Calcium Nitrate (15.5-0-0) $ 21.00 $ 64.00 Select options. This process removes the residual Sodium and Potassium complex in the Coco coir. Use only correctly washed and buffered coir products such as our Dutchman Brand Premium Expanded Coco Coir. What is a good Coco Coir, Perlite, and Additives recipe or pre mix? study was to select the most suitable particle size range for coco peat to be used as a nursery substrate to produce greenhouse tomato, bell pepper, cucumber and cabbage seedlings.

Accessories Perlite- Once the process of washing with water is completed then the coir is rinsed well with a solution of calcium nitrate for a long time. Flush with 200-400 ppm of Base before planting- 1/4 tsp. This gives the medium a distinct advantage over other mediums that need pH conditioning before use. Then prepare the buffer solution to 200PPM in RO and flush it again until the runoff leachate is also 200 ppm. Additionally, due to the cation exchange properties of coir, some calcium is immobilized (held) and higher levels of Ca are required in formulation (along with Ca Mg buffering prior to use). I have heard many contend on forums that coco specific nutrients are not required to produce bumper yields in coir. Once expanded, prepare a vegetative solution with an EC of 2.5 3.0 and a pH of 5.8 (if possible, maintain a N:Ca ratio of ~1:1). When planting into Coco we suggest the following 3 protocol: 1. Nutrient buffer. The water soluble particles are removed after a thorough washing with clean water. It is then pre-treated with a calcium fertiliser such as calcium nitrate to enhance the potassium-calcium exchange. A good rule of thumb is to use 2 gallons of buffering solution for every 1 gallon of coco coir. Drain any excess solution and rinse the cocopeat with pH balanced water. Our mission at California Substrates is to provide growers with the very best grow media for their operation. Uh, the salts are really, really low. Growing Solutions. Fully buffered Using Calcium Nitrate & Gypsum. Coco coir buffering begins with flushing and rinsing the fibers with clean water. They become calcium and magnesium bonds (cation++). A very simple method is to use a bunker (wash bay) system to buffer the coco peat. If I knew the coco was not properly buffered at the factory, I wouldnt buy it. The process that we call buffering involves soaking the washed coir pith in a calcium nitrate solution before flushing again with fresh water. You dont need to precharge your coco with calcium nitrate. Buffering of coco peat removes elements that are naturally bonded to the cation exchange complex (CEC) of coconut coir peat. To overcome the nutritional imbalances, coco peat is buffered and triple washed to remove elements soluble in water, which removes elements that are naturally bound to the cation exchange complex. Additional Uses: reptile bedding; potting mix; soil amendment; Calcium Nitrate (15.5-0-0) $ 21.00 $ 64.00 Select options. About DoubleThumb. Inert Media Buffering. In order to decrease the coirs levels of sodium nitrate and chlorine, a process known as buffering is used, where the coir is treated with calcium nitrate instead. Three main horticultural coir products can be obtained from this husk; coir chips, coir fibre or coir pith/dust (see picture 1). Step 3: We give the coir a second wash in fresh water by leaching part of the salts from the chemical buffering process.This achieves an EC of 0.4mS/cm in a measurement of 1 volume of the substrate in 1.5 volume of water. Pack Out Per 40' HCB - 27,600 Kg Floor Loaded / 24,600 Kg Palletized.

Place coco in a fabric pot - and then place that into a 5-gallon bucket. But most decent coco is already pre-buffered. During the buffering process, coco coir cation exchange complex is saturated with a solution of calcium nitrate for an extended period. The micronutrient part is 2% magnesium. (Used for preparing non-buffered coco substrates such as compressed coco blocks) Calcium Nitrate 290 g/l Magnesium Nitrate 280 g/l Magnesium Sulphate 10 g/l Place the hydrated/expanded and water flushed coir into the diluted buffer solution and leave to soak for at least one hour. Place coco coir in a container at least 5x the size of the block. Limited time only. Methods for extracting these elements and thus lowering EC are yet to be standardized. We know that the sodium can easily be leached from the material using irrigation. Soak for 20-25 minutes until coco coir has expanded to maximum volume (4-5 x original size) breaking up large pieces by hand will speed the process. Coir has become a major component of both greenhouse vegetable and container crop production. During the buffering process, coco coir cation exchange complex is saturated with a solution of calcium nitrate for an extended period. For example, many coco product manufacturers buffer their coco with 8 kg of calcium nitrate per cubic meter of coco. Horticultural & Hydroponic High Grade, washed, sieved and compressed Low Inherent EC (Average 300 S/cm) 100% Organic Coco Coir Peat and Coir Chip. You shouldnt need to buffer quality coco because its already is buffered with calcium nitrate to remove excess sodium. Buffering the coco coir displaces the sodium and potassium bonds (cation+). Why buffer coco peat? Coconut Coir. What is buffering. water mixed with Coco-Wash) per 1 Cubic Meter (or +/- 15 x 5kg blocks) of coco-peat/coir alternatively 1,000 litres of water mixed with 13 kgs of Coco-Wash will buffer 5 Cubic Meters of coco-peat/coir. It is 100 percent Coco Coir, it has the RHP certification which is the calcium nitrate buffer to displace potassium. Note: The buffering process involves pre-soaking with a Cal-mag, which displaces the sodium and balances the naturally occurring potassium. Among all the treatment processes, the buffering of coco coir is one of the main treatments done on the coco coir. The buffered coir offers several advantages thus have a high demand in Indian as well the international market. Peat/mineral soil: nutrients bind to the fibres or particles using charged sites know as Cation Exchange Sites. [Quote] Potassium and phosphorus concentrations in coconut coir were two and eight times higher than those in rockwool. During this buffering method, the coco coir cation exchange complex is drenched with a solution of calcium nitrate for a comprehensive period. U are suggesting to add 7.5 Gms of calcium nitrate for 1 Lit of water. Most bales of dried coco are compressed in a 6:1 ratio. Cocos CEC, can be as high as 400, while a good quality soil is around 80-100. Buffering is the process that also removes elements naturally bound to the cation exchange complex. Coco peat is then usually (but not always) treated with calcium nitrate solution to buffer it and remove sodium. Compressed blocks should expanded with a 2.0 EC calcium nitrate (or bottled cal-mag) solution with the ph adjusted to 5.8. This topic has 1 reply Posts.
