Hi Peeps
A quick question for them that know!!!
I have just set up a Wilma system put it all together washed my clay through in the bags then put them in the pots filled the system & switched on the pump I let it run for a few hours drained the tank down refilled the tank with fresh water & let it sit for 24hours then done my PH levels got them at 6.1.
Then I checked my EC levels just out of curiosity & I'm getting a reading of 0.4!!!!!
How is this possible when I have not added any nutrients????
Sorry if I'm being thick but can someone enlighten me please
