About Growth Technology
The products
Formulex is a complete feed used at low strength for seedlings, cuttings and mother plants. Liquid Oxygen is a hydrogen peroxide solution that oxygenates a reservoir and sterilises a system between crops. Liquid Silicon strengthens stems and leaves. The calibration and probe solutions keep pH and EC meters honest.
Looking after meters
Calibrate every couple of weeks, store the probe in storage solution, clean it when readings drift.
