These Easy Life Root Stick come as a tub of 25 sticks, and can be fed directly to plant roots, with the compact clay sticks being placed directly into your substrate, where they will release nutrients gradually over a period of weeks to provide optimum fertilisation.
These are 55mm clay sticks that are very nutritious, with a high iron content. They have been designed to gradually release nutrients, and won't break apart within the water, or cause any cloudiness. Ideal for plants with a strong need for root nutrition, such as Cryptocoryne, Echinodorus or Lotus. For small plants, or a thin layer of substrate, these sticks can be broken to smaller pieces if needed.
Dosage is 1 root stick per 15cm2 of soil surface, and you just need to place the stick into the substrate layer.
