When you growing plants using Hydroponics, very often we deal with cocopeat substrate with varying quality. It is very important for us to know how to determine the quality of cocopeat we are working with.
In this video, I am going to explain the process of measuring Electrical conductivty and pH of cocopeat sample. I use 1:2 dilution method for the measurement.
1. Take 200ml of Reverse osmosis or distilled water. Measure its EC. Note it as ECw
2. Take a 100ml sample of cocopeat and mix it with the 200ml water.
3. Mix the slurry well and allow it to settle for 15 mins
4. Now filter the mixture with a filtering cloth or a mesh.
5. Measure the EC of the filtered liquid and note it as ECs
6. EC of cocopeat is ECs-ECw
7. Measure the pH value of the filtered liquid. That is the pH of the cocopeat.
8. Analyse both the readings and evaluate!
This video is a must watch if you have the following questions
1. How to measure the salt content of cocopeat
2. How to measure pH of cocopeat or cococoir
3. How to measure TDS of cocopeat
4. How to check if cocopeat is good for hydroponics

Thanks for the gyan daan. God Bless you. Can you suggest a good supplier of Cocopeat bricks 5kg/low EC for exports.

@skoka123 2 года назад

Awesome. Very informative for beginners.

@TheGeekgardener 2 года назад

Thank you Srikanth. Let's catch up sometime

@gabrielillo79 Год назад

Hi, great video. What humidity % does the100 ml cocopeat sample that you use have? And if hydrated, then what water type your use to hydrate it before starting the test?

@nanguteali2302 2 года назад

Really informative as always ! Do you have a guide on how to this for rockwool medium ?

@TheGeekgardener 2 года назад

Thanks for your kind words. Rockwool medium is relatively more inert than cococoir and not so brittle / powdery like cocopeat. This makes it a lot easier to measure its EC ( which is infact the solution EC the rockwool is saturated with). Over time the rockwool slab can get salt accumulation which can be measured by inspecting the drain EC. I dont have rockwool with me. I will try and see if we can make a video in future.

@atulagarwal5514 2 года назад

A small request: plz make a video about how to make a stock solution for ec and ph calibration. Ph calibration pouches are available in market or online but ec is a tough nut to be sure of. Plz try providing a solution for that in upcoming videos if possible.

@TheGeekgardener 2 года назад

Atul, if i understand right, you are asking you the buffer solutions for calibrations correct?. pH 4, pH 7 and EC buffer solutions? I will definitely make a video. Thanks for the suggestion 🙌

@atulagarwal5514 2 года назад

@@TheGeekgardeneryou got my point sir. Ph buffer solutions like 4 and 7 are available. But as far as i know, nothing is available for ec calibration. Plz share share some light as to how we can make accurate ec calibration solutions at home or where to buy... Thanks for the quick replies sir. Appreciate your efforts. 👍

@sitharadassanayaka9603 7 месяцев назад

Sir i want to know how to do darin analysis .beacuse i planted plants in polytunnel by using cocopeat and need to check Ec can you help me

@samuelbaladad4295 8 месяцев назад

Hi, I was wondering if the coco peat that you used as a sample in taking EC & pH parameters was previously buffered.

@TheGeekgardener 8 месяцев назад

The cocopeat I used wasnt buffered. Buffered cocopeat is quite expensive in India and is preferred only for certain commercial projects. one can always do the buffering themselves, if required.

What if the water used to mix is ph 6.5? I want to test ph.

@amitdumbre1590 2 года назад

What to do if the ph value of coco peat is 8.5? How to bring it down to 7?

@John-rd5nq Год назад

My question seems stupid 🙈 sorry for that ... Can i use the TDS meter to check the EC conductivity and use any chart conversion table to check the EC level ?

@TheGeekgardener Год назад

Totally valid question. Yes you can use the TDS meter and convert it as per the factor provided by the manufacturer of the TDS meter.

@atulagarwal5514 2 года назад

After harvesting, if small roots get left in cocopeat, does that technically increase carbon content in cocopeat?

@TheGeekgardener 2 года назад

It does increase. Cocopeat as a growing medium also compacts over time. The older roots will disintegrate in few weeks.

@atulagarwal5514 2 года назад

@@TheGeekgardener thank you for your valuable replies sir. Love your videos. The practical essence in it really makes them valuable. Plz keep uploading to make us beginners more knowledgeable.

@rahuldalavi4081 Год назад

Why we are measured ec, ph of cocopeat

@atulagarwal5514 2 года назад

Hello sir. Supposedly i have harvested a plant and now i want to use the same cocopeat again in another plantation. How do i seperate the cocopeat from the roots that are left in the cocopeat after harvest???

@TheGeekgardener 2 года назад

Atul, If the cocopeat is in a opentop grow bag, its a lot easier to remove and take out the old roots ( or even simply let to dry). but in a closed grow bag(like the slabs), its very difficult to remove the old roots. Its a practice to plant the new ones next to where the old ones were cut off. Anyways beyond two crops, the media is recommended to be changed.
