Frequently Asked Questions(FAQ)
What is perlite used for?
Perlite is used in soil mixes (including soilless mediums) to improve aeration and modify the soil substructure, keeping it loose, well-draining, and defying compaction. … Other uses of perlite include masonry construction, cement and gypsum plasters, and loose fill insulation.
Can I reuse coco peat?
Coco peat gardening is also used as a soil amendment, potting mix, and in hydroponic production. Coco coir is so environmentally friendly that it is reusable. You just need to rinse and strain it and it will work perfectly again.
What do clay pebbles do?
Clay pebbles are lightweight and porous which holds air in them and increases the aeration for the root system of the plant. The structural formation of these hydrotons is such that it is light in weight and has enough space inside to capture the air and let it release whenever the plants or harvest needs it.
How clay balls are made?
Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a lightweight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
