Hey there folks.
I am digging and searching for more information on this topic and cant find much using the search thread, and also have some interesting observations i would like to share with community.
I have been told doing a slurry test is a more accurate way to determine what is happening inside the coco medium. As opposed to just testing the runoff. What is surprising to me is how different these readings are coming out at. For instance:
I was getting runoff readings of 2.5 EC. in veg where i feed at about .5. This caused me concern so i did some slurry tests and these readings came out at .7
The way i do my slurry is to put about a cup of medium from the middle of one of my pots into a container and then add water at a 2/1 ratio. Then i let it sit for 30+ minutes. Then i either strain the coco out, or don't strain it (i am surprised to be getting the same reading, strained or unstrained), and put my probe in and get the EC reading. It is consistently A LOT lower than my runoff reading.
Anyone know why my slurry reading would be so much lower than a simple runoff reading? This has been happening with multiple meters, in many different pots.
It is recommended to use ditilled or RO water, which if i am looking for my coco PH i do, but when checking EC i just use my .2 EC tap water and subtract that out of the reading...
This stuff interests the heck out of me, and hopefully you as well, cause i wants to learn!!!
