| green onion on vermiculite+perlite |
|
Dear collegues.
I try grow chives (type of green onion) in the mix verviculite+perlite 50%-50%. fluid has PH 6.5 (about , i checked by paper) , EC - 1300 microsiemens . NPK 18-18-18.
Problem - when i add fluid into substrat , PH is reduced to PH 7 and upper.
What i can do ? how i can reduc PH for perlite and for vermiculite ? as i checked it is them put free ions into fluid.
I'm From Moscow Russia, i already asked on russian agronom persons but they do not what need do because here not big expirience in this substrated.
