miten muuta EC arvon ppm arvoksi

[sinappi]

Käytän EC mittaria joka ilmoittaa arvot mS
miten ne muutetaan ppm arvoksi

Mikä on sopiva EC arvo chileille vesi viljelyssä?

[cornell]

Should we use or atleast try to use english here at international area?

Flora Mato dosage guide gives EC values for each dilution... what I did was I calculated the total ppms using NPK values of the macronutrients and got folloving results:

ml/10l
mi 1 + ma 1 EC 0,85 ja tot. ppm 190
mi 2 + ma 3 EC 1,60 ja tot. ppm 481
mi 3 + ma 4 EC 2,10 ja tot. ppm 671

I typed this into exel and got linear graph with function y = (0,0026*x) + 0,355

So according Mato info EC = (0,0026*ppm) + 0,355  and ppm would be
Ppm = (EC-0,355)/0,0026.

Please let me know if I've made some mistake ! This is not an exact way to calculate EC/ppm values but should do.

Right EC for chillies in hydro? Can't help you... I would gues there is no simple answer to that. Different varities have different needs and IMO there's contradictory info about nute strenghts around...

here's something:

Many growrs here at inferno dilute their nutes to half strenght from what is recomended until the plants start to grow pods...

I use 20-30% of recommended amount of nutrient all the time quite successfully with chiles....flowering or vegetative growth.
