Greenhouses: a response to the climate, but a challenge for the earth
An essential solution to climate change
Droughts, heavy rains, late frosts: weather hazards are increasingly weakening crops.
Greenhouses help secure crops, extend production cycles, and protect plants from moisture-related diseases.
This is why greenhouse cultivation areas are increasing every year in France.
An often ignored setback
By blocking rain, the greenhouse interrupts the natural cycle of water and organic matter.
The soil is no longer rinsed or oxygenated.
Microfauna – worms, bacteria, fungi – gradually disappear.
The earth becomes dry, compact, sterile.
In the long term, the soil loses its natural fertility: the greenhouse protects the plant, but forgets the living things that nourish it.
Recreating greenhouse life with Jamet pottery
At Poterie Jamet, we have chosen to give back to the earth what it loses under cover: water, matter and biodiversity.
Our ceramic pots – Ollas and buried composters – help to restore a living ecosystem, even without rain.
L'Ollas: water in the right dose
In a greenhouse, watering is often irregular: too much or not enough.
The Ollas, a microporous terracotta pot, slowly diffuses water according to the plant's needs.
Result :
- 50 to 70% water saved
- a soil that is always fresh without stagnation
- deeper and more vigorous roots
The buried composter: feeding the soil from the inside
Biowaste placed in the composter is decomposed directly in the soil by worms and microorganisms.
This process releases stable nutrients and restores soil life without odors or rodents.
Result :
- continuous biological activity
- a richer and more aerated soil
- a natural cycle completed in a greenhouse
A more resilient and natural agriculture
By combining Ollas and an underground composter, we recreate the vital trio: water, organic matter and microfauna.
This is the key to living soil, even in an artificial environment.
Plants become more heat resistant, fertilizer requirements decrease, and productivity remains stable over the long term.
It is both an ecological and economical approach, which places nature at the heart of greenhouse cultivation.
Sustainable pottery, based on local know-how
Each Poterie Jamet piece is handcrafted in our workshop.
Our ceramics are 100% natural, plastic-free, designed to last for decades and neutral for the soil and biodiversity.
Choosing our pottery means choosing common sense and a deeply rooted ecology: local, sustainable and respectful of living things.
Towards a more vibrant greenhouse
In greenhouses, rain never falls, but life can be reborn. With Jamet pottery, you recreate the natural cycle of water and matter, even under cover. Ollas and buried composters: living soil for a sustainable harvest.
