The HerbNest Refill Kit contains:

  • Nitrogen for leafy growth and plant health.
  • Phosphorus for root development and flowering.
  • Potassium for water regulation, boosting flower and fruit development.
  • Magnesium for improved photosynthesis.
  • Plus, Iron, Manganese, Copper, Zinc, and Boron.

These are essential for plant cell development and nutrient transport.

Plant Food B:

Nitrogen, Calcium, Magnesium

This formula strengthens cell walls, prevents root rot, and has more magnesium than plant food A, enhancing photosynthesis even more.


*Why 2 parts?

  • Some nutrients (like calcium and phosphate) can react negatively when mixed in the same solution.
  • Using a two-part formula prevents nutrients from turning into solids, maintains nutrient stability and availability, and delivers a complete and balanced feed for plants.

15 x Nests

The nests are specifically designed to fit into the HerbNest, secure the plant's weight, and ensure its roots have access to water.

15 x Sponges

The sponges simulate a seeds natural environment, safely anchoring the young sprout while allowing them to absorb as much water and nutrients as they need.
