Description

A root stimulator that runs from the first week of growth

Plant Vitality RZM (Root Zone Mass) is a root growth stimulator combining NPK with humic acid, fulvic acid, plant vitamins, lecithin and protein molecules to encourage multi-directional root development. It is dosed at 2ml per litre every week from Grow 1 to Flower 7.

The formula is designed to build the root structure a plant needs to take up nutrients and water efficiently, and suits all substrates as well as hydroponic and aeroponic systems.

Key Benefits

  • Stimulates multi-directional root development
  • NPK with humic and fulvic acids, vitamins, lecithin and protein molecules
  • All substrates, including hydroponic and aeroponic systems
  • Simple dose - 2ml per litre, every week
  • Runs most of the cycle - Grow 1 to Flower 7

Slow roots holding the whole plant back?

A plant can only feed as fast as its roots allow. RZM goes in from the first week of growth so the root mass builds early and keeps building, giving the plant a bigger root zone to draw on through flowering.

How to Use

  • Dose: 2ml per litre of water
  • When: every week from Grow 1 to Flower 7
  • Add to your Plant Vitality base feed, stir, then check pH and EC
