• Wash your beads thoroughly to rinse off residue and dust.
• Check their pH:
Put some beads in a glass of demineralised water (pH<4.0). Stir well and leave to rest.
Measure the pH. If it is high (pH>7.0) then soak overnight in an acidic solution (pH<4.0). Then rinse thoroughly.
If necessary, especially if your plants have suffered insect infestation or disease we recommend correct disinfection.
Soak in strong pH Down overnight and rinse thoroughly.
