I just set up my first hydro setup there last nyt. im not to sure how to read my ec meter correct can anybody give me a little guidence. the manuel that came with it was very vague! Its a 138(II) conductivity tester and it measures up to 0-1999us/cm.
I am using "Marijuana indoor growing" by Philippe Adams, as a refrence but its telling me i need a EC reading of 0.8 for seedling?
with the meter i have the tap water reads 320, when i added nutes it read about 520. i went up a few hours later and it was at 710. what does this mean? i added more water to bring this reading down 540 again but i dont no what it means.
Im using a 8 pot wilma system but only have 4 plants in it.
the nute that i used was canna start, i put about 50ml into 70ltrs of water which is well below what it recommends. I dont what to fry them but i do want to give them all they can take.
I tested rain water around the farm its ranging from 050-094 would this be better to use instead of the tap water?
finally im from N.Ireland if that make any difference
please help asap
