## Description

Horticultural Charcoal for Plants - 290G Natural Earth Regulated Supplement for Potting Soil Indoor Plants, 3-5mm Succulent Soil, Organic Biochar, Paphiopedilum, Bonsai

## Features

- Temperature Regulator: Charcoal absorbs and retains the heat of sunlight, so that the soil temperature is regulated and seeds are promoted to germinate.If you want indoor plants to grow healthily, horticultural charcoal is an ideal choice
- Water and Nutrient Storage: Charcoal performs well in storing water and nutrients, and can improve soil permeability and drainage (especially for containers without drainage holes). When fertilizing or watering is excessive, the charcoal will store the excess and release it when needed
- Good Filter: Due to the loose and porous structure of horticultural charcoal, it can effectively increase the air flow in the soil of plant pots, especially for indoor plant soil with less air circulation
- Suitable Size: Horticultural charcoal has a diameter range of 3 - 5 mm, and small pieces of charcoal that moderately cover the soil surface help plants survive and reproduce
- Multi-functional: Charcoal blocks are suitable for various soils, including potting soil for indoor plants, soil for succulents, and soil for indoor plants with good drainage. It is very suitable for a variety of plants such as Cattleya, Dendrobium, Vanda, Paphiopedilum, and can even be used as a practical decoration in fish tanks and glass containers
