Testing PPM

How do I test PPM from the runoff? In felt pots…:thinking:

Well whenever the water runs out of the bottom I to your collection tray then you would use your TDS meter to get the ppm reading.


Ok was using a big wad of kitchen paper :roll_of_toilet_paper: and squeezing :laughing:

Can someone give me the ppm numbers for veg and flower inc runoff?

Every plant is different. You have to learn how to read your plants. Watch some videos, read some botany stuff. It will all start to become easier and easier then more grows you have


So true so many different was to be successful;)
